7.0 Final release

(#792) The sorted triangles transparency types used the SoMaterial color when they should have used the vertex property color. This problem applied to the following transparency types: SORTED_TRIANGLES_ADD, SORTED_TRIANGLES_BLEND, SORTED_OBJECT_TRIANGLES_ADD, SORTED_OBJECT_TRIANGLES_BLEND.

(#940) There was an incorrect floating value comparison in SbRotation::setValue method. When using a tab box dragger and scaling down to obtain a plane, sometimes the following message appeared: Inventor error in SbRotation::setValue(const SbMatrix &)(): Rotation does not agree with matrix; this routine only works with rotation matrices!

(#1708) 2 SoTexture2 nodes based on renderToTextureProperty can't be rendered in 1 scene graph

(#1108) SORTED_TRIANGLES_BLEND transparency didn't support multi-texturing display. Only the first texture was displayed.

(#1137)[Enhancement] SoAnnoText3 shapes with renderPrintType set to RENDER2D... had limited text size. User can now change the default value by using the OIV_MAX_VIEWING_FONT_SIZE environment variable or the SoAnnoText3Property::setMaxViewingFontSize() static method.

(#1197) Incorrect refresh of popup and menu bar in Qt application during large scene animation. Sometimes the viewer popup or menu bar became semi-transparent. This was a manifestation of the timing issue reported in ebug #1565.

(#1245) Materials defined inside an SoIndexedTriangleStripSet were ignored by the transparency types SORTED_*TRIANGLES_BLEND.

(#1397) The methods setRadius and setRay of rayPickAction can't be used simultaneously to define a world-space ray along which to pick.

(#1455) Crash occurred when using ivToVRMLAction (Same as #1837.)

(#1565) OIV_QT_TIMER_THREAD was not working in OIV 6.0.1. This is not an issue working with Qt 4.x. When working with Qt 3.x, you must use the following workaround: set OIV_DELAY_SENSOR_TIMEOUT to 0 set OIV_QT_TIMER_THREAD to 1

(#1669) Animation on large scene stopped when the QtExaminer viewer popup menu was mapped. See #1565 for workaround.

(#1691) SoTexture3 crash when 3 2D images are defined in the field filenames.

(#1740) In some cases, SoRayPickAction didn't return the right shapes when using setRay(). Now the default field of view angle is 0.0003F and can be redefined by the user to adjust the view volume used internally by SoRayPickAction by using the OIV_SET_RAY_PRECISION environment variable. There is also a new vrsion of setRay() that takes an fovy.

(#1746) SoRayPickAction::setRay failed to select shapes when the Z component of the ray was greater than 10. This is because clipping to the near and far planes was supposed to be disabled when using negative (or default) values as the 3rd and 4th parameters of SoRayPickAction::setRay().

(#1747)[Enhancement] SoSFImage did not allow storage of an image size larger than 32767 (MAX_SHORT). The type of m_size field (SoSFImage) has been changed from SbVec2s to SbVec2i32 to allow support for larger images. For compatibility, functions taking SbVec2s as argument have been kept.

(#1761) The viewer popup and Qt combo box couldn't be used during Qt viewer spin animation. Specifically, the popup and combo box sub-menus weren't displayed. See #1565 for details.

(#1774) When SORTED_OBJECT_TRIANGLES_BLEND transparency was enabled, all objects were rendered with the material of the first transparent object.

(#1775) Crash when selecting SORTED_OBJECT_TRIANGLES_BLEND transparency after SORTED_LAYERS_BLEND transparency.

(#1812) Shapes added under a fastEdit Separator in a nodekit weren't displayed.

(#1837) SoToVRML(2) Action crashed when applied to SoIndexedTexture nodes. It crashed in SoConvertGuts::convertSoVertexProperty.

(#1859) Some DXF files containing leading white space were not read correctly due to an error in SoInput.

(#1875) The Open Inventor installer modified DevStudio settings without asking for customer consent. Consent was requested for setting environment variables but not for modifying the Visual Studio settings. #### What settings?

(#1900) A problem deriving a new element class was fixed. SO_ELEMENT_INIT_ABSTRACT_CLASS erroneously created a new classStack index.

(#1968) Buffer overflow problems that occured when trying to use more than 10 passes in DELAYED_SORTED_LAYER_BLEND or SORTED_LAYER_BLEND transparency mode.

(#1973) Using FLEXnet license caused a small memory leak.

(#1965) SORTED_LAYERS_BLEND and DELAYED_SORTED_LAYERS_BLEND transparency types caused GL errors.

(#1940) [Enhancement] Request a way to generate then to visualize LDM volumes with more than one voxel overlap. Bigger overlap area allows better interpolation than the classic bilinear approach. Furthermore, this improvement fixes lighting artifacts between slices. -b option of SoLDMConverter now supports values greater than 1.

(#1976) Textured characters became black squares when one zoomed in.

(#1977) The override flag was written to .iv files by SoWriteAction if the programmer had set the override flag in his application. This caused issues for users who expected to be able to read their new .iv files in older versions of Open Inventor.

(#1979) SoFragmentShader and SoVertexShader did not generate any warning or error message when a specified shader source file could not be loaded.

(#1980) [Windows] Crash in connectFrom when allocating 3GB before loading Inv6xx.dll. The crash happened when connecting the 16th or 32nd field. It only crashed when the Inventor dll was placed in memory areas 32bit.

(#1981) Crash in the constructor of SoRenderToTextureProperty. It didn't crash in 6.0.3.

(#1983) SbLinear.h generated error when using strict compiler options on g++ 4.1.1 due to a namespace defined at the very end of the file with a semi-colon after the closing brace..

(#1985) Crash trying to set useAutoMipmap field (inherited from SoTexture).

(#1990) SoQtMaterialEditor and SoQtDirectionalLightEditor crashed in constructor.

(#1993) [HP-UX] libIvDLLm wasn't provided in the HPUX distribution of OIV 6.1.1. This lib was required for floating licenses AND for installation without DirectViz password.

(#2000) SORTED_(OBJECT_)TRIANGLES_BLEND types crashed in RegularGrid3D demo.

(#2001) IvDLOpenAL32.dll and the IvDLZlib.dll were not versioned correctly, which prevented installers from overwriting previous versions of these two DLLs.

(#2007) Changing the value of SoColorMap::predefinedColorMap didn't immediately update the display.

(#2012) There was a crash in SbThreadMutex::unlock when displaying SoVolumeIndexedFaceset. The same application worked with OIV 6.1.1 on Win32.

(#2016) The was a run-time error when enabling DirectViz in debug mode. Runtime Error ! Program: C:\... R6034 An application has made an attempt to load the C runtime lib incorrectly.

(#2021) [Windows] Upon exit of the example program MFCSDI, the VC++ 8 compiler reported a memory leak. The fix was to add SoWin::finish() to the application.

(#2022) [Unix] The IvDL* libs depended on libInventor.so. It wasn't possible to build a static Open Inventor binary that didn't require separate Inventor/image dynamic libs. Now it is possible.

(#2023) All of the HLHSR modes (except HIDDEN_LINES_REMOVAL) crashed SoVectorizeAction or produced empty output files. It worked in 6.1.1.

(#2029) When using transparency type SORTED_LAYERS_BLEND or DELAYED_SORTED_LAYERS_BLEND with half-screen stereo, one of the views was black.

(#2036) IvDLLm provided in OIV 6.1.2 for VC8 depended incorrectly on some Microsoft debug DLLs: MSVCR80D and MSVCP80D. It should only depend on release versions of Microsoft dlls.

(#2037) SoNodes.h, a header file provided for convenience, was missing some headers, such as SoSelection.h and SoExtSelection.h.

(#2040) Markers couldn't be displayed when a groupAxis was added to the scene and the binary was built with static OIV libs. It worked in OIV 5.0.5.(Same as ebug 2041.)

(#2041) [Linux] Crash in SoXt::finish after loading an .iv file containing a group3Axis and a MarkerSet shape. The crash only occurred when the application was built with static Open Inventor libs.

(#2048) [Windows] Heap corruption occurred when loading in SceneViewerD a sphere with a low complexity. No error was seen in release mode.

(#2064) OIV_NO_FLEXNET env variable has been added in order disable 's checking of FLEXnet licenses. This can be helpful at times to avoid conflicts between the Open Inventor FLEXnet license checking and FLEXnet license checking that the application may be doing in order to work with other software packages.

(#2073) SoDB::readAll didn't properly load an engine with at most 2 input fields and at least 1 connected field. The connected input field was duplicated when reading such an engine.

(#2074) Unexpected GROUP_REMOVE_CHILD trigger occurred on nodes where no child was deleted. This remove_child trigger happened on a node (abnormal) and its child (normal) when the child of its child was deleted.

(#2083) Crash when loading an SoTextureCubeMap in an application initialized with threadInit, even if there was no thread created. It didn't crash if init was called instead of threadInit.

(#2085) 3D text strings sometimes affected the lighting of downstream primitives (since Open Inventor 6.0).

(#2092)[Enhancement] SoRayPickAction now has a getNormalizedPoint method to go with its setNormalizedPoint method.

(#2114) Setting the ignore flag of an SoText3 node affected the normals of subsequent face sets.

(#1826) SoNodes referenced DirectViz headers that are not part of the public distribution. Duplicate of #1853. [P2]
(#1831) With the SoWinComponent::helpFileName specified, a second browser displaying the Open Inventor help file appeared as well. [P2]
(#1832) The field SoWinComponent::helpContextString wasn't used by Open Inventor. [P2]
(#1841) Some compiler warning messages seen when using VC 8.0 have been eliminated.
(#1853) Duplicate of #1826. [P2]
(#1866) When SoFont::name was set to Arial, conversion to VRML should have produced SoVRMLFontStyle::family = SANS. [P2]

Final release

(#1166) SoDB::finish now frees the dictionary and typeData tables.
(#1429) Method SoHandleEventAction::setPickRadius had no effect. The method SoHandleEventAction::getPickedPoint forced the pick aperture of SoRayPickAction to 5 pixels.
(#1430) [Enhancement] Method SoSelection::setRadius(float radiusInPixels) is now implemented.
(#1458) [Enhancement] [Windows] PDB files of DLLs in release mode are now provided in the Windows distribution.
(#1490) [Windows] The IVF AppWizard did not install properly nor work correctly with Visual Studio .NET 2003.
(#1501) [Windows] When installing OIV 6.0 for Visual Studio 2005, the customization of the IDE's directory lists (i.e., include and lib) failed. The error message was:
```
    Severe: The customization file is missing.
```
(#1562) [Enhancement] [Windows] InvQt6xxBuilder has been enhanced to use the highest version of the Open Invenftor library that it finds in the directory. Previously it would use the first one (alphabetical order).
(#1594) The .pro files weren't provided with the QT4 examples.
(#1635) When the field SoTexture3::minFilter was set, the OpenGL resource GL_MAG_FILTER was set.
(#1662) Unknown information nodes with a declared field couldn't be read in Open Inventor 6. For example, the node:
```
    DEF FileInfo CustomNode {
    fields [SFName name, SFFloat width,SFFloat depth,SFFloat height]
    name "Table"
    width 2.00
    depth 0.90
    height 0.863
    }
```
could be loaded/saved in Open Inventor 5 but not with Open Inventor 6.
(#1695) SoNodeSensor callback returned the root node of the modified VRML nodes. It should have returned the modified node itself as done for Open Inventor nodes.

(#1702) [Windows] IvTune Shift-F12 failed for VS 2005 debug builds. The error dialog:

    "This application has failed to start because MSVCR80.dll 
    was not found. Re-installing the application may fix this problem."

(#1706) Memory leak when modifying the field SoTexture2::image. It could be seen when the field was modified in an SoOneShotSensor callback. This problem did not occur if only one texture (and always the same) was modified in the callback.
(#1711) RGB files referenced in SoTexture2 nodes weren't closed.
(#1720) [UNIX, Linux] Double buffering was disabled when redrawing the scene on window events. This was seen on Linux RHEL3 (Opteron) and on Solaris 8 (suntotal2) when the viewer received resize or expose events.
(#1726) Crash using SoQt::finish. The crash happened in SoQtSensorHandler::setUpPendingTimers but *only* in debug mode.
(#1728) [Enhancement] Open Inventor stopped searching for a valid password if the file $OIVHOME/license/password.dat existed and no valid password was found. Now it continues searching in other license files that it can find.
(#1729) [Linux] SORTED_LAYERS transparency types displayed opaque shapes.
(#1737) SoDB::readAll returned NULL when loading DXF files. This was broken in Open Inventor 6.0.3.
(#1738) removeChild didn't remove an SoSelection node when objects had been selected.
(#1745) Crash when calling SoSelection::getPath(0) if no object had been mouse-selected.
(#1752) [UNIX, Linux] Auto clipping was re-enabled when stereo display was ON. This issue happened with SoXt but not with SoWin.
(#1754) SoText2 with renderStyle TEXTURE ignored material changes.
(#1755) Stroke font text that was dragged and dropped several times sometimes disappeared.
(#1757) Text with renderStyle TEXTURE were displayed opaque when transparencyType wasn't SCREEN_DOOR, except when transparency type was Sorted Triangles or Sorted Object Triangles, in which case the text wasn't displayed at all.

Triangle transparencies cannot be supported by textured text. Therefore the documentation has been updated and the textured text is forced to be rendered using:
- BLEND transparency when using SORTED_TRIANGLES_XXX_BLEND
  and
- ADD transparency when using SORTED_TRIANGLES_XXX_ADD.
(#1762) minFilter and magFilter fields of SoIndexedTexture2 had no effect on the displayed textured shapes. The values were not being sent to OpenGL.
(#1766) Nodes outside SoLocateHighlight were redrawn when the mouse is when the cursor was over the contents of the locate highlight. Only the "selected" node should have been redrawn. This problem didn't occur if the nodes outside the locate highlight were opaque.
(#1774) When SORTED_OBJECT_TRIANGLES_BLEND transparency was enabled, all objects were rendered with the material of the first transparent object.
(#1777) [UNIX, Linux] IvTune/SoIvTune.h header file was not supplied with Linux/Unix SDK.
(#1787) SoWindef.h redefined "system" items like Display or GC.
(#1788) Calling SoXt::init after calling SoXt::finish caused a crash in SbNameEntry::insert.
(#1792) [Linux] RGB files generated on Linux were invalid.

Open Inventor 6.0

Patch 3: Bugs fixed as of November 27, 2006

(#1246) Dragger selection behaved abnormally when stereo was enabled. [P3]
(#1391) Under some circumstances, an SoIndexedTriangleStripSet surface disappeared unexpectedly when under an SoOctreeOrdering node. [P3]
(#1394) At certain angles an SoIndexedLineSet under an SoOctreeOrdering node disappeared from the display. [P3]
(#1429) Method SoHandleEventAction::setPickRadius had no effect because the pick radius was always forced to 5 pixels. [P3]
(#1453) SoOffscreenRenderer::writeToJPEG(NULL) saved an invalid JPEG image in memory. [P3]
(#1519) After using the mouse wheel to move an object, you had to click twice on the viewer buttons or thumbwheels to use them. [P3]
(#1541) Various DLLs for the Open Inventor 6.0 VC8.0 build had incorrect or missing version info in their Properties dialog. [P3]
(#1550) SoTextureCubeMap didn't support HDRI texture files. No texture was loaded when the field SoTextureCubeMap::filenames was set to an HDRI file. [P3]
(#1559) JPEG amd BMP offscreen output of polygonal Text3 failed. The text did not appear in the output. (Same as #1576) [P3]
(#1564) SoQtSpaceball was broken using Open Inventor 6.0 and 6.0.1 on Linux. The symptom was a dialog stating that "No driver is running. Exit." [P3]
(#1566) When the field SoFile::name was modified, the SoDataSensor::getTriggerField method returned NULL. [P3]
(#1569) The Ladmin tool for Open Inventor 6.0 for Win64 put the license string in the wrong place in the system registry. [P3]
(#1571) The Ladmin tool for Win64 did not return the correct computer ID. It returned the actual MAC address, whereas on Win64, the digits must be switched around. [P3]
(#1573) After using the mouse scroll wheel, clicking on the application toolbar generated numerous errors (and crash). [P3]
(#1574) Same as 1573. [P3]
(#1575) Open Inventor didn't release the MouseEvent if the mouse wheel had been used. (Same as ebug #1254). [P3]
(#1576) Offscreen rendering of text did not work. No text output appeared in the output .bmp file, only the non-text geometry. (Same as #1559) [P3]
(#1577) Stroke fonts didn't work correctly with the GDIPrintPreview example. The characters were rendered extremely small. [P3]
(#1578) The SoText3 display lists were not valid when changing context, creating artifacts during offscreen rendering. [P3]
(#1580) SoVRMLArc2D did not change appearance when fields were changed. For example, if the application changed the radius field, the arc should have changed appearance (be drawn with the new radius value). SoVRMLArcClose2D, SoVRMLCircle2D, and SoVRMLDisk2D all had the same bug. [P3]
(#1584) The text of GLSL compile error messages was not printed. When compilation of a GLSL shader fails and OIV_GLSL_DEBUG is set, Open Inventor should print the text of the error message from OpenGL. Now it does. [P3]
(#1589) The selection cursor wasn't displayed in SoQtWalkViewer, SoQtPlaneViewer, or SoQtFlyViewer. The error in the DOS console was:

QCursor::update: Invalid cursor shape 25
(#1610) An SoCubeMap node specifying an HDRI file and exported by the writeAction could not be reloaded (crashed).
(#1611) Method SoFieldContainer::set crashed when the input parameter was large. [P3]
(#1634) 3D textures weren't displayed when SoComplexity::textureQuality > 0.6. [P3]
(#1636) 3D textures weren't displayed when the X and Y texture dimensions were 1024. [P3]
(#1638) SoFragmentShader and SoVertexShader now display filename in error message. Previously if the specified shader program file was not found, Open Inventor displayed this message:

Inventor error in SoShaderObject::readSource()()
Unable to read source program
[P3]
(#1639) Same as #1638.
(#1640) Texture image "file not found" message now includes the filename. Previously if Open Inventor was unable to open the specified shader program source file, the error message said:

SoRasterReaderSet::getReader
Can not open file !
[P3]
(#1645) SoImageBackground didn't restore the OpenGL state. glPixelStorei (GL_UNPACK_ALIGNMENT, ...) GL_CLIENT_PIXEL_STORE_BIT was missing from the push attrib call. [P3]
(#1648) A volume geometry node surface flickered one/two times when used with LOD node. This only happened when LOD was linked to "Frame per second" mode. [P3]
(#1652) Stroke font glyphs were positioned incorrectly and/or missing when using a release build (on Windows). [P3]
(#1655) When fastEditing and Reverse Left/Right views were enabled, the raw stereo was only displayed in 1 view. [P3]
(#1659) In QtLargeModelViewer 6.x changing the type of viewer from Examiner to Plane/Walk/Fly viewer caused a crash. Fixed in SoStereoDialog and SoQtFullViewer. [P3]
(#1660) [Linux] Changing the type of viewer from Plane/Walk/Fly to Examiner viewer didn't work. No redraw was issued. [P3]
(#1663) Geometry was drawn transparent when DELAYED_ADD was set, even though no geometry had any transparency. This problem was introduced in Open Inventor 6.0.1. [P3]
(#1664) Marker set animated rendering in Qt viewers was jerky. [P3]
(#1679) SoDB::readAll didn't automatically recognize DXF files. [P3]
(#1684) The NodeSensor callback wasn't always triggered when SoVRMLTimeSensor fields were modified. [P3]
(#1685) The search policy of SoDynamicLibManager was invalid when using the environment variable OIVHOME. [P3]
(#1689) SoTexture3 crashed when the field filenames was empty or only specified one file. [P3]

Patch 1: Bugs fixed as of July 12, 2006

(#708) When displaying text using renderStyle TEXTURE, sometimes the character edges appeared jagged. [P1]
(#1080) Many macro redefinitions were listed as warnings during compilation when SoDialogVizAll.h was called before SoQtExaminerViewer.h. [P1]
(#1154) Text drawn with renderStyle TEXTURE didn't support French or German font names. [P1]
(#1183) PROTOs didn't write out correctly for certain PROTOs. If the PROTO definition's field definition contained a node and therefore had a { }, the buffer containing the PROTO definition (for later writing out) wasn't correct. [P1]
(#1213) The materialBinding was ignored on SoCube when at least 1 face was transparent and SORTED_LAYERS_BLEND or SORTED_TRIANGLES_BLEND or SORTED_OBJECT_TRIANGLES_BLEND was enbabled. [Fixed in Open Inventor 6.0 final]
(#1278) [Enhancement] A method SoFont::isSupported(char* font_name) was added to filter the fonts supported by Open Inventor. [P1]
(#1292) Incorrect display of accentuated text (e.g., "T�xt") during manipulation with an SoTransformManip. [Fixed in Open Inventor 6.0 final]
(#1305) SoSplitGeometryAction changed the appearance of the split object when normals weren't provided in the scene graph. In the case where normals were computed by Open Inventor, the computed normals of the initial shape should have been stored in the split shapes. [P1]
(#1328) Configuration parameter OIV_FONT_RENDERSTYLE didn't support the text values POLYGON, TEXTURE, and POLYGON_AND_OUTLINE. It only supported values 0, 1 and 2. Now it supports the text values as well. [P1]
(#1422) Text crashed when OIV_PSFONT_PATH was too long on Solaris. [P1]
(#1452) QtLargeModelViewer showed a flickering display when tooltips or toolbar menus were mapped. This was related to Qt 3.3.6. [P1]
(#1469) If the scene contained SoText2 and "auto clip planes" was enabled, the viewer contents sometimes flashed/flickered when zooming in. This was due to an intermittently invalid bounding box. [P1]
(#1471) When a window was closed and then reopened, its resources were not reloaded properly. Causing, for example, the following error:

SoWinBitmapButton (dialog banner)
Could not get bitmap from resource module.

[P1]
(#1472) A program consisting entirely of SoDB::init() and SoDB::finish() crashed due to a null pointer. [P1]
(#1477) When SCREENDOOR transparency was enabled, all opaque shapes added after the selected shape beceme transparent during navigation. The selection was made through an SoLocateHighlight node. The issue didn't happen with SORTED_OBJECT_BLEND transparency. [P1]
(#1478) SoLocateHighlight didn't properly restore the color of opaque shapes encapsulated in transparent objects. The issue happened in SORTED_OBJECT_BLEND transparency type. [P1]
(#1479) SORTED_LAYERS_BLEND failed to render an opaque cube inside a transparent cube. The external cube was rendered as an opaque shape. [P1]
(#1481) When the requested or default fonts weren't found, non-text shapes weren't rendered either. The following message was displayed:

Inventor error in SoFontBase::SoFontBase():
Error while creating Freetype Face object.

[P1]
(#1482) QtHelloCone and QtReadFile for Qt4 crashed in debug mode. [P1]
(#1487) Draggers/manipulators were affected by shader nodes (but should not have been). [P1]
(#1492) Opaque text strings became transparent during navigation with SCREEN_DOOR transparency type and renderCaching set to ON. It didn't happen if renderCaching was disabled or set to AUTO. [P1]
(#1500) Same as #1532. [P1]
(#1504) Large texture couldn't be displayed when using certain graphics cards (e.g., NVidia Quadro FX 3400/4400 and NVS 285). The problem occurred with images larger than the graphics board capabilities. [P1]
(#1508) Same as #1532 [P1]
(#1524) Textured non-left-aligned text strings weren't displayed at the correct position. The bounding box of textured text (i.e., text drawn with renderStyle TEXTURE) was incorrect. [P1]
(#1531) When mouse events were continuously caught by the eventCallback, the Qt viewers never rendered the scene. [P1]
(#1532) deleteValues() on a multi-value field, e.g., SoMFInt32, destroyed the last value when the next-to-last value was deleted. For example, if you deleted item 1 from the coordIndex field of an SoIndexedPointSet, deleteValues() trashed the value of item 0. [P1]
(#1536) SoPackedColor without value was displayed semi-transparent. It should be displayed opaque (default documented value is 0xccccccff). [P1]
(#1537) Stroke fonts didn't display in Open Inventor 6.0. No error message was displayed. [P1]
(#1538) Applying SoGetPrimitiveCountAction to a scene graph that contained a stroke font crashed the program. [P1]
(#1560) [Windows] It was not possible with Open Inventor 6.0 to link an application with the compiler setting "treat wchar_t as a built-in type". This fix may be of relevance to applications using Unicode strings. [P1]
(#1624) At certain orientations, text strings were erroneously clipped by the clipping planes when "auto clip planes" was set on the viewer. [P1]

Final release

(#594) The SoQtColorEditor and SoQtMaterialEditor did not go away when they were deleted.
(#1049) Objects were displayed too dark in SORTED_TRIANGLES_BLEND transparency type when the SoMaterial::transparency field was modified.
(#1230) If two selection nodes were added to a scene, the second selection did not receive an event.
(#1264) If SoCamera::ViewportMapping was set to LEAVE_ALONE and stereo was enabled, the scene wasn't displayed.
(#1296) Multi textures were sometimes displayed incorrectly when the transparency type was set to SORTED_LAYERS or SORTED_TRIANGLES.
(#1297) Under some circumstances, SORTED_LAYERS transparency was switched to SCREEN_DOOR when one was navigating around transparent objects.
(#1322) Incorrect display of some Open Inventor files when the transparency type was SORTED_LAYERS_BLEND.
(#1332) The display was incorrect when using SORTED_LAYERS_BLEND transparency when a textured object intersected other objects.
(#1334) Objects under a non delayed transparency type node became invisible when SORTED_LAYERS_BLEND was enabled.
(#1335) Objects under a DELAYED_xxx transparency type node became invisible when SORTED_LAYERS_BLEND and highlighting (e.g., pick highlighting) were enabled.
(#1351) If more than one color was specified for an SoPointSet or SoMarkerSet, and it was followed by an SoLineSet, when the the scene was rerendered, the color of the last line segment was used for the color of the first point or marker. This only occurred if caching was on (the normal state).
(#1356) SORTED_LAYERS_BLEND transparency used to be hard-coded to use texture unit 1. Now it used the highest numbered texture unit available on the hardware in order to minimized conflicts with other uses of the texture unit.
(#1390) An SoOctreeRendering node did not work correctly with sorted transparency type rendering.
(#1395) Transparent SoImage nodes were rendered opaque when the camera direction didn't match the order of the image nodes in the scene graph.
(#1405) There was a memory leak during navigation on VRML shapes and non-SCREENDOOR transparency types.
(#1420) SoOffscreenRenderer modified the viewer's viewport when the viewer GLRenderAction was used by the offscreen renderer.
(#1423) There was a crash in the NURBS tessellation using Open Inventor 5.0.5.
(#1424) The MFCSDI and MFCMDI example programs flashed when their windows were resized. This was an application problem related to OnEraseBkgnd.
(#1440) An instance of SoWriteAction failed to export more than two .iv files. This occurred with Open Inventor 5.0.5 and Visual C++ 7.1.
(#1441) SoWriteAction prevented cout from displaying messages.
(#1445) Some STL entry points were wrongly exported to the Open Inventor libraries, leading to possible duplicate entry points when linking an Open Inventor application that uses STL.

Open Inventor 5.0

Patch 5: Bugs fixed as of October 2, 2005

(#403) Textured NURBS (SoNurbsSurface) failed to display on recent graphic boards. The display was correct when HW acceleration was disabled or when old graphic cards were used (such as Elsa Erasor X2 or S3 Savage3). [P5]
(#1157) Some textured NURBS (SoNurbsSurface) in debug mode aborted in the assertion "pspec[0].range[1] > ptb[0]". The old (from SGI) textured NURBS code was replaced with new code by Mercury. [P5]
(#1242) The iv import/export in binary mode of MFVec3d fields generated invalid values. [P5]
(#1251) QtxxxViewer crashed when mapped if the viewer was built without decorations. [P5]
(#1254) Open Inventor didn�t release the MouseEvent if the mouse wheel had been used. [P5]
(#1255) Draggers did not respond to mouse events when they were in the scene after an SoSelection node, but not inside it. [P5]
(#1257) SoVRMLInline and SoWWWInline didn�t process ROUTEs. Field-to-field connections defined in the url field were lost. [P5]
(#1268) There was a crash when displaying an IndexedTriangleStripSet with an empty materialIndex and with a PER_PART_INDEXED material binding. [P5]
(#1271) SoExtSelection crashed on Solaris when useOverlay was enabled. (This problem was introduced in OIV 5.0.4.) [P5]
(#1277) The destructor of SbProjector needed to be declared public instead of protected. [P5]
(#1279) There was poor texture quality on 3DLabs Realizm boards if the application set the textureQuality field in its SoComplexity node to a value < 0.8. [P5]
(#1280) If a texture has some transparency, the object to which it is applied was treated as transparent even when the texture was applied in DECAL mode. [P5]
(#1281) Same as #1255. [P5]
(#1286) Transparent objects sometimes became opaque under SCREEN_DOOR transparency type due to incorrect state tracking. [P5]
(#1293) An empty SoIndexedLineset crashed in the method SoIndexedShape::setupIndices when materialBinding was set to PER_*_INDEXED . [P5]
(#1302) The Jpeg API function jpeg_resync_to_restart was erroneously prefixed MCS_ in OIV 5.0.4. This is now fixed. [P5]
(#1311) SoFaceDetail could provide the wrong index when the winding rule was not NO_WINDING_TYPE. [P5]
(#1321) For large images, when SoOffscreenRenderer tried to stitch the tiles back together to form the single large image, it did so incorrectly. [P5]
(#1330) Historically, SoSelection::handleEvent has always continued on even when a child of the SoSelection handled an event such as clicking on a dragger. The old way, the selection/deselection callbacks were called but they should not have been. It now works as it should. That is, the selection/deselection callbacks are NOT called when a child of an SoSelection node has handled the event. [P5]
(#1339) SoIntersectionDetectionAction missed some intersections when the numbers were very large. Double precision is now used in all the intersection calculations. [P5]
(#1340) When mouse events are continuously caught by the event callback, the Qt viewers do not update the scene as often as necessary.

Because of the way that Qt's QTimer class works, the timeout for processing the delay queue did not always occur, and the scene was not updated. The configuration parameter OIV_QT_TIMER_THREAD set to 1 causes a separate thread to be used to signal the delay sensor timeout. The default behavior is the same as before to avoid possible side effects in existing customer applications.
(#1348) [HP-UX] It was not possible to run multiple Open Inventor programs simultaneously because the license manager opened a specific device to get the machine identifier, but didn't close this device if the identifier was found.

Patch 4: Bugs fixed as of June 6, 2005

(#1063) A ray pick action (SoRayPickAction) failed when the ray intersected a NURBS surface shape (SoNurbsSurface) on a corner of the triangles resulting from the NURBS surface triangulation. [P4]
(#1074) Methods SoExtSelection::getLassoCoordsDC and getLassoCoordsWC crashed when called before selection or when lassoType was NOLASSO. [P4]
(#1075) SoExtSelection::getLassoCoordsDC() and getLassoCoordsWC() crashed when useOverlay() had been called. [P4]
(#1085) Texture "leaked" from one piece of geometry to another. [P4]
(#1096) IvTune: If you deleted a piece of geometry from a scene, then did a "Save as...", IvTune crashed. [P4]
(#1110) On IRIX (and probably other Unix platforms), the RotateCylindricalDragger caused a floating point exception. [P4]
(#1120) SoFont::renderStyle TEXTURE sometimes displayed text in POLYGON style. [P4]
(#1126) There was a memory leak in SoRayPickAction::apply(). [P4]
(#1140) SoRayPickAction failed when the ray intersected shapes having small coordinates. [P4]
(#1143) SoRayPickAction::computeObjVolAndLine sometimes attempted to set a zero length line. When working with large magnitude numbers, using the projection direction vector to create the second point of an SbLine could cause a zero length vector to be created and an error message displayed in debug mode. [P4]
(#1146) SoGetBoundingBox action didn't include the first or last blank lines in the box computation of text. The problem occurred with multi-strings set on a text node including blank line(s) at the beginning and/or end of the MFString field. [P4]
(#1147) Remote render stopped working in 5.0.3 (no image displayed). [P4]
(#1149) The SoMPEGxxxRenderer classes were missing methods for setting the viewer OpenGL context to be shared by the offscreen renderer. The following two new methods were added: setShareContext() and getShareContext(). [P4]
(#1150) [UNIX] The make command failed when launched in $OIVHOME/src/Inventor and $OIVHOME/src/Inventor/examples. [P4]
(#1151) The CSG tree was displayed incorrectly if first rendered as SoGroup (isActive FALSE), then as CSGGroup (isActive TRUE). [P4]
(#1153) SoFile nodes that had setSearchOK to TRUE could crash. [P4]
(#1162) QtWalkViewer::setSceneGraph crashed on scene graph including an orthographic camera. [P4]
(#1164) [Solaris] When Open Inventor was running, it was impossible to create a cursor bitmap having dimensions greater than 32x32. This limitation appeared in Open Inventor applications as well as in X11 applications that did NOT have Open Inventor calls if Open Inventor was running on the server. [P4]
(#1168) SoExtSelection selected a line set even when the lasso policy was not fulfilled. The problem happened when a LineSet enclosed separate shapes. When lassoPolicy was FULL and lassoMode was ALL_SHAPES, putting the lasso between the shapes, not enclosing or touching any of them, selected the entire object. [P4]
(#1174) The SoExtSelection lasso was unexpectedly drawn on mouse motion and mouse button UP. [P4]
(#1184) SoSearchAction didn't return the expected number of paths on VRML nodes. All returned paths were duplicated. [P4]
(#1185) After using the mouse wheel to move the camera, the mouse had to be clicked twice on any viewer button or thumbwheel to use it. [P4]
(#1186) SoChildList::addPathAuditor and removePathAuditor were not thread safe. [P4]
(#1187) SoText3 was not thread safe. When SoText3 was used in multi-threaded applications, it could crash when setting up the font. [P4]
(#1199) When the SoShapeHints winding type was any type *except* NO_WINDING_TYPE, a face set with multiple faces where not all the faces had holes did not display correctly. This change affected SoIndexedFaceSet, SoFaceSet, and SoVRMLDisk2D. [P4]
(#1206) [SGI/IRIX] Text displayed in render style TEXTURE crashed in gluBuild2DMipmaps due to a problem in the GLU library. If updating the GLU library does not resolve the problem, you can now disable the use of gluBuild2DMipmaps by using a newly added environment variable OIV_TEXTURED_TEXT_NO_MIPMAP. [P4]
(#1208) SbViewportRegion::setPixelsPerInch had no effect on the offscreen 2D text size when the viewport region was defined in an SoGLRenderAction. [P4]
(#1232) Memory leaks in the SoQtMaterialEditor, SoQtColorEditor, and SoQtDirectionalLightEditor were fixed.
(#1239) SoSplitGeometryAction crashed when there were multiple colors in the geometry being split.

Patch 3: Bugs fixed as of March 11, 2005

(#963) An SoTabPlaneDragger with a very large scale factor in X and Y (small in Z) did not work correctly. The tabs changed the dragger position instead of resizing the dragger. [P3]
(#966) SoNode::copy didn't copy the userData data. [P3]
(#981) A mono-thread application behaved abnormally if threadInit was called. The following error message was displayed in debug mode:

Inventor error in SbThreadRWMutex::writelock():
wait timed out...

This problem didn't occur with OIV 4.0. [P3]
(#982) The Qt viewer's zoom slider didn't handle floating values. For cross-platform consistency, it now behaves like Xt and Win viewers which allow floating values. [P3]
(#983) A VRMLElevationGrid with no xSpacing or zSpacing values specified drew an correct picture (a straight line). Default values of 1.0 should have been used. [P3]
(#987) [UNIX] The File Selection box size was variable on UNIX. Now the size is set to a default if its initial size is not valid. [P3]
(#991) [Enhancement] Distributed example programs that read a user geometry file have had the following lines added to the code:

SoWWWInline::readAsSoFile(TRUE);
SoVRMLInline::setReadAsSoFile(TRUE);

This allows inline files to be read immediately as Open Inventor files. Without these lines, only a bounding box for the inline geometry would be drawn. [P3]
(#1009) [UNIX] Previously, the SoQt-based demos (e.g., VolRend, QtLargeModelViewer,...) displayed informational messages about the Space Mouse (SpaceBall, Magellan). These messages are no longer displayed by default. [P3]
(#1014) Duplicate of #1022. [P3]
(#1016) If you had a camera and a transform directly under a separator, the transform sometimes "leaked" out of the separator. [P3]
(#1019) SoInput did not release the file handle after reading the scene. (Duplicate of #1048). [P3]
(#1022) SoFieldContainer.set(SbString str) did not correctly parse the specified argument. Due to an unitialized variable in SoInput, only the first item in the string was read. This caused, for instance, the Inventor/Mentor/15.4.Customize program to draw the wrong picture. [P3]
(#1025) If the numVertices field was not specified for SoFaceSet, SoLineSet, or SoTriangleStripSet, and normals were specified with a VertexProperty node, the geometry flickered as the camera was moved. (Every other frame was not being drawn.). [P3]
(#1029) [UNIX] Some makefiles were missing, others did not work as delivered. [P3]
(#1039) Erroneous error message. When INVR500.DLL couldn't be found, the error message stated:

SoWin resources not loaded
Cannot find INVRES.DLL

INVRES.dll is the old name of the DLL. [P3]
(#1044) A crash occurred in SbBox::getSize when floating exceptions weren't ignored. When the following function was called:

_control87( _RC_NEAR + _PC_53 + _EM_INVALID + _EM_INEXACT + _EM_DENORMAL, _MCW_EM);

SbBox::getSize crashed. This didn't crash in OIV 4.0.6. [P3]
(#1045) Animation in a VRML file failed when the TimeSensor was an SoVRMLPROTOInstance. [P3]
(#1048) Files opened by SoInput::openFile were not closed. This bug was introduced in OIV 5.0.2. (Duplicate of 1019). [P3]
(#1060) The center of an OpenFlight LOD was not parsed correctly. It was always set to 0,0,0. This could cause the wrong nodes to be displayed when moving the camera through a scene. [P3]
(#1066) If you were sufficiently devious, it was possible to draw the SoExtSelection lasso without pressing the mouse button. [P3]
(#1069) Picking outside the viewport (this is possible when using one of the "crop" viewportMapping values on the camera node) generated an unhelpful zero-length line warning. [P3]
(#1070) [Win32] Several help-related issues were fixed:
- All viewers: the righthand ? button now brings up the Open Inventor help file (the Reference Manual). Previously this did not work correctly with VC 7.0 and VC 7.1.
- The SceneViewer was modified to remove non-functional help items:
  - - The toolbar Help button (black ? and arrow).
  - - All Help menu items except for "About Sceneviewer".
[P3]
(#1083) Single pass antialiasing didn't smooth the lines, but lines become thicker. This worked correctly in OIV 4.0. [P3]
(#1100) Texture objects sometimes were applied on the wrong piece of geometry. [P3]

Patch 2: Bugs fixed as of December 10, 2004

(#857) With certain scene graphs, ivfix (-a) exited after assertion failed. [P2]
(#882) The Qt libs (e.g., libqt-mt.so.3.1.2) were missing from the Open Inventor distributions for UNIX platforms. These libs are necessary to run the prebuilt demos QtLargeModelViewer and IvTuneViewer. [P2]
(#892) *_TRIANGLES_BLEND transparency types crashed on scene where SoSwitch disabled/enabled transparent objects. [P2]
(#897) [Windows] OpenGL calls from the user application failed when done after the creation of an SoOffscreenRenderer (because the current OpenGL context was set to NULL). The offscreen renderer constructor no longer changes the current context. The OpenGL calls generated error 1282. [P2]
(#898) When doing a box highlight (SoBoxHighlightRenderAction) on a scene with SORTED_TRIANGLES_* transparency type, the resulting image was incorrect. Specifically, the transparent triangles were rendered again after the action was applied to render the box highlight. This blended more (i.e., too much) of the transparent object's color into the scene. [P2]
(#902) [Enhancement] SoOffscreenRenderer could only deal with viewports with dimensions that could fit into a short (up to 32767). This limitation has been lifted. [P2]
(#904) Transparent PNG textures which contained a background were rendered without transparency.

A new environment variable was added to force the old behavior where the background replaces transparent pixels. Set OIV_ENABLE_PNG_BACKGROUND to 1 if you want the old behavior. [P2]
(#911) Shapes disappeared after the scene graph was modified when delayed/sorted transparency was used. It is essentially the same as eBug #859, except the fix for #859 did not handle the case when the transparent objects were inside nodekits. [P2]
(#915) Under some circumstances, the error "Requested feature was omitted at compile time" was displayed when you tried to write a JPEG file. This occurred when a JPEG library other than the one that comes with Open Inventor was loaded (in addition to the JPEG library supplied with Open Inventor). [P2]
(#918) In some cases, SoExtSelection crashed when part of the rectangle or lasso was outside the render area. [P2]
(#919) SoExtSelection crashed or didn't clear the old lasso/rectangle from display when the scene included mesh representations. [P2]
(#925) Rendering caused the ref count of nodes to be incremented but never decremented, causing a memory leak. [P2]
(#926) In some cases, using multiple instances of the same node under the same separator caused auditor problems when there were more than 250 instances. [P2]
(#927) TIFF files with non standard file extensions (.e.g, .tif.crp) couldn't be loaded by SoTexture nodes. [P2]
(#928) In some cases, shapes disappeared from the display when SORTED_OBJECT_TRIANGLES_BLEND transparency type was enabled. [P2]
(#931) Selection failed when applied on a lineset including a null length line segment. [P2]
(#933) Reading a VRML file containing a PROTO and also a VRMLLOD or a VRMLSwitch node would cause the application to crash with a stack overflow. [P2]
(#936) OpenFlight files couldn't be loaded unless the OpenFlight file type was specified using SoInput::setCurFileType(). Open Inventor should have been able to recognize OpenFlight files automatically. [P2]
(#937) Texture files with pathname specified relative to the Open Flight file that used them could not be found. [P2]
(#945) [Linux] SoQtExaminerViewer crashed when one switched to single or interactive buffer. The crash occurred in the method SoQtGLWidget::setDoubleBuffer. [P2]
(#955) [HP-UX] The Open Inventor license manager for HP-UX didn't work on permanent passwords. The license manager searched for an old hostID instead of the MAC address (correctly provided by MCScomputerID). [P2]
(#956) The OpenFlight reader failed on a group having faces not defined at the end of the group. [P2]
(#957) SoExtSelection crashed on cube selection when setPointFilterCallback was enabled and lassoPolicy was set to PART. Open Inventor tried to add a NULL path in the selection list. [P2]
(#958) SoOffscreenRenderer crashed when tiling was required and the image size wasn't a multiple of 4. [P2]
(#960) [Windows, VC6] Some applications based on the Open Inventor 5.0.1 patch crashed when the SoOffscreenRenderer object was deleted. [P2]
(#961) Offscreen rendering didn't support multipass anti-aliasing and non screendoor transparency. [P2]
(#967) In the Open Inventor 5.0.1 patch, an Inventor error in SoRasterReaderSet::getReader() occurred when attempting to use non RGB texture files. [P2]

Patch 1: Bugs fixed as of October 15, 2004

(#495) A memory leak in SoText3 and the SoFont classes was fixed. [P1]
(#768) SoIntersectionDetectionAction failed when a line intersected a cube in a corner or an edge. Fixed in SoIntersectionDetectionAction. [P1]
(#839) An intersection was found on non-intersecting objects. Fixed in SoIntersectionDetectionAction. [P1]
(#840) SoOffscreenRenderer::writeToJPEG failed to write the JPEG compression stream to a buffer. [P1]
(#849) The following methods:

- SoField::disconnect (SoField *field)
- SoField::disconnect (SoVRMLInterpOutput *interpOutput)
failed when connecting any two unlike types, for example, an SoMFloat connected to an SoSFloat. [P1]
(#852) SoMultipleCopy and SoArray nodes were not displayed correctly if one of the delayed or sorted transparency modes was in effect. Also SoBoxHighlightRenderAction now correctly highlights the whole object, not just one of the multiple or array copies. [P1]
(#858) SoMPEGNavRenderer crashed when no camera was found in the scene graph. This was fixed. Also, now SoMPEGNavRenderer will find cameras that are in a nodekit. [P1]
(#859) Shapes disappeared from the display when a delayed/sorted transparency type was enabled and a switch node was modified. [P1]
(#860) When SoSelection::setPickMatching(FALSE), no pick was made. [P1]
(#861) Intersection detection failed on some scenes depending on the world position. [P1]
(#862) SoDB::createGlobalField crashed when called with the name of a global field which had been destroyed (renamed to empty string). [P1]
(#865) [Mac] There was a problem with the appearance of the sliders of the Open Inventor material and color editors. [P1]
(#871) Transparent objects were not displayed correctly under the following conditions (all conditions must apply):
- The scene graph contained an SoBackground node,
- followed by an SoAnnotation node,
- followed by some transparent objects.
- One of the delayed or blended transparency modes was being used. [P1]
(#873) See eBUG 874. [P1]
(#874) QtLargeModelViewer crashed if SoQt::finish() was called and the scene was animated when the viewer was closed. Inventor objects (like SoxxxViewer) must be destroyed before calling the finish() method. This info has been added to the finish() method. [P1]
(#888) Some of the draggers, e.g., SoHandleBoxDragger and SoDragPointDragger, did not respond correctly to direct manipulation. [P1]
(#895) When doing a box highlight (SoBoxHighlightRenderAction) on a scene with transparent objects and any kind of delayed transparency, the resulting image was incorrect. The transparent objects were being rendered twice, which blended too much of the transparent object's color into the scene. This has been fixed for DELAYED_x and SORTED_OBJECT_x transparency types. The SORTED_TRIANGLES_x transparency has not been fixed. [P1]
(#896) When using packed colors (SoPackedColor), some objects that should have been transparent were rendered as opaque. [P1]

Final release

(#109) Interlaced PNG image files were not processed correctly, causing Open Inventor to crash.
(#251) Application would freeze during zoom manipulation while NurbsSurface shapes were spin animated. It also happened on trimmed NURBS. This would happens more quickly or less quickly depending on the graphic board. See also eBUG #754.
(#292) Setting antialiasing (setAntialiasing (TRUE, 1)) and transparency type SORTED_OBJECT_ADD caused opaque faces to appear transparent. Same as eBUG #457.
(#439) A SoPointSet containing only one point wasn't displayed if the scene didn't include any other shapes.
(#464) A crash occurred when the render methods of the SoOffscreenRenderer and SoBigImageRenderer classes were both called. This is no longer a problem since SoBigImageRenderer is now derived from SoOffscreenRenderer.
(#501) The SoBigImageRenderer class did not correctly manage scenes having multiple light sources. Only the first light in the scene graph had an effect in the .tiff image. Fixed when SoBigImageRenderer features were incorporated into SoOffscreenRenderer.
(#528) The OGLInfoUnix program in Open Inventor 4 always reported direct rendering as supported even when you were using a remote display. The printf statement for this test was missing a %s so the string "NOT " was never output.
(#532) The DEF name "VRML" was lost when VRML2 output was written to a file.
(#565) The SoVRMLExtrusion geometry was generated incorrectly at the beginning and the end of the spine, causing the extrusion to be misshapen.
(#570) The class SoQtSpaceball wasn't implemented.
(#580) On Nvidia, best interlaced stereo was very slow. The new "best" algorithm uses textures to save and re-render the intermediate images. It is quite fast on modern hardware.
(#585) Octree ordering did not work correctly with LOD and transparent objects. With delayed transparency, all of the transparency objects beneath the LOD were not delayed but were rendered as if they were not delayed.
(#597) QtLargeModelViewer was missing options/controls compared to the MFC version of LargeModelViewer:
- VRML inlines weren't loaded.
- Drag/drop didn't work.
- Back face culling couldn't be enabled/disabled.
- Smooth normals couldn't be generated.
(#683) The zoom slider of the ExaminerViewer was not updated by software modification of the camera heightAngle. The zoomSensor in SoWinFullVwr wasn't attached to the camera when the viewer was mapped to the screen. This attachment only occurred when the cursor of this slider was moved.
(#685) The license manager now gets ALL the Mac addresses of a PC configuration and unlocks the product if one of them fits the installed password (command ipconfig/all).
(#687) The Open Inventor plugin for QtDesigner didn't compile with Open Inventor 4.0.
(#688) SoExtSelection::getLassoCoordsMC (not implemented) has been removed from the header file.
(#691) Previously it was inconvenient to install Open Inventor for Visual Studio .NET and Visual Studio .NET 2003 on the same system.
(#714) [UNIX only] Open Inventor didn't link properly in static mode on SGI.
(#718) ivfix grouped shapes that had different textures, thus only the first texture was used.
(#728) The SoExtSelection FULL lasso policy may fail. When part of a line was surrounded by the rectangle, another line was selected. The correct line was selected if the entire line was surrounded. When the lasso policy was FULL, Open Inventor did not check the bounding box against the lasso.
(#731) When using SoExtSelection, objects were deselected when the viewer was maximized by double-clicking in the window title bar.
(#732) Animation performance was poor if the viewer popup was displayed.
(#736) The VRMLSpotlight cutoff angle was twice as big as it should have been.
(#737) The material binding was not correctly applied to a PointSet when a directly referenced VertexProperty node was used. If the orderedRGBA field of the VertexProperty node has no values, the materialBinding field should be ignored. However, it was not being ignored.

This same problem was in many of the shape nodes: SoLineSet, SoFaceSet, SoTriangleStripSet, SoIndexedLineSet, SoQuadMesh, SoIndexedQuadMesh, SoIndexedTriangleStripSet, and SoIndexedFaceSet.
(#738) A crash occurred if the drawing style was set to Bounding Box and the text of an SoText3 or SoAnnoText3 node was changed.
(#739) Some parts of the scene graph were disappearing after a redraw due to a caching problem.
(#745) VRMLMovieTexture crashed or provided no image when connected to a Philips camera because the resolution set by Open Inventor did not take into consideration the capabilities of the connected camera.
(#746) If a transparency field had multiple values, even if they were all zero, Open Inventor assumed that at least one of them was non-zero. Due to a bug in the internal tracking of the transparency state, the result was that some objects were drawn transparent when they should not have been.
(#747) The SoQtColorEditor::hide method didn't work. The editor remained on screen.
(#749) [Windows only] On Windows, .jpeg files were not read (as a texture). Only .jpg files were read. Both file extensions should have been recognized. On UNIX, there was no problem.
(#750) If the filename field of SoTexture2 was blank, an error was generated even in an application built with the release target.
(#751) The middle mouse button didn't work when using the Animations/FreeView feature of QtLargeModelViewer. The middle mouse button (in PICK mode) is supposed to move you closer to or further from the object. This worked in OIV 4.0 and 4.0.4, but had no effect OIV 4.0.6 and OIV 5.0 Beta 2.
(#752) [UNIX only] After creating and deleting a first viewer, you could not create and show a second viewer because the baseWidget (created by SoXt::init) was freed by the viewer destructor.
(#754) Textured NURBS display froze during navigation in the scene. When loading and moving a NURBS+Texture Object in the viewer, there was no response and 100% CPU usage. Untextured NURBS were fine.
(#758) SoOffscreenRenderer didn't output SoText3 or SoAnnoText3 nodes. Broken in OIV 4.0.6.
(#759) Colors were lost on non-convex FaceSet when materials were given externally to the shape and the points internally. Only the first color of the materials list was applied to the shape.
(#761) Textures were (sometimes) mapped incorrectly onto SoVRMLElevationGrid shapes. They were mapped according to the usual Inventor behavior instead of following the VRML spec.
(#772) Open Inventor did not recognize alpha values in TIFF files.
(#773) When using SoExtSelection with lasso policy PART, lines that were not inside the lasso might be selected, depending on the arrangement of the geometry.
(#777) Using delayed transparencies could cause multiple rendering for transparent shapes that were children of SoSwitch, when the SoSwitch whichChild field was set to SO_SWITCH_ALL. The problem appeared only when several transparent nodes were children of the SoSwitch.
(#778) SoOffscreenRender crashed if you did a render and then getBuffer.
(#782) Only the first row of tiles was rendered by SoOffscreenRenderer when using getBuffer(). This problem did not become apparent until after eBUG #778 was fixed.
(#783) SoOffscreenRenderer::setMaxTileSize() was declared in the header file, but was not exported by the DLL, causing a link error.
(#784) One could not override createViewerButton in SoQtExaminerViewer. When a viewer was subclassed from SoQtExaminerViewer, and the createViewerButton() was overriden, the code compiled correctly, but no button appeared. The problem was due to the button size not being set internally.
(#787) There was a problem with the SoOffscreenRenderer constructor that takes a SoGLRenderAction. It did not initialize the viewport region.
(#788) SoOffscreenRenderer::getDC always returned NULL if doing tiled rendering.
(#796) Open Inventor was crashing when the number of coordinates in an SoVRMLIndexedFaceSet was less than 0.
(#803) SoTexture2 did not close a BMP that it loads. Repeated changes of the texture by loading different texture files would eventually lead to having too many files open.
(#809) There is a conflict between Qt and X11 in the definition of KeyPress and KeyRelease. This caused compilation errors in certain applications that used SoQt header files. The header files have been modified to avoid this problem.
(#812) SoText2 clipping fails sometimes, especially when the scene is highly zoomed.
(#826) When the Qt viewer's zoom slider was set to 0, the application crashed or output error messages in debug mode.

Open Inventor 4.0

Patch 6: Bugs fixed as of January 20, 2003

(#300) SoRayPickAction failed on a strongly zoomed scene. Fixed in a previous patch but not documented.
(#391) SoToVRML2Action changed the input scene graph if the input scene graph contained a vertex property node. [P6]
(#435) The SoMPEGFrameRenderer class did not always record the complete animation. Fixed in a previous patch but not documented.
(#457) Opaque objects became transparent when smooth antialiasing and ADD transparency were enabled. [P6]
(#491) SoQtFullViewer::setClientPopupMenu didn't allow you to define a custom popup menu. The only way to set a custom menu was to change SoQtFullViewer::mainPopup directly. [P6]
(#492) If a Qt viewer was created without any standard popup, the program crashed. [P6]
(#513) QtLargeModelViewer needed various minor cosmetic tweaks to the user interface. [P6]
(#549) The mouseMotion events were never sent to the event callback of the Qt viewers. [P6]
(#606) QtLargeModelViewer adaptative viewing problem. The toggle "Do full rendering when still" had no effect on the display (the image remains simplified when still). In addition when you closed and reopened the "Adaptive Viewing" dialog, the choice on this toggle was lost. [P6]
(#656) Improved performance on interlaced stereo. Fixed in a previous patch but not documented.
(#694) Method SoPNGImageRW::loadPNG sometimes crashed. This bug was introduced in OIV405. [P6]
(#696) (Same as 711) Texture loading failed. The texture bitmap files couldn't be opened. This bug was introduced in OIV405. [P6]
(#697) SoToVRML2Action appeared to modify the width of the displayed lines if the input scene graph contained a vertex property node and if antialiasing was enabled. In fact, part of the OpenGL state was getting lost; the lines appeared wider due to the effects of smoothing and antialiasing. [P6]
(#698) The ELLIPSE lasso type of SoExtSelection wasn't correctly drawn in an non-square viewer. [P6]
(#702) The SoOffscreenRenderer::writeToBMP method produced empty images if a big viewport was used. This bug was introduced in OIV405. [P6]
(#704) The transformBoxDragger couldn't be resized if it was centered on (0.,0.,0.). The error message was: "Inventor error in SbLine::setValue(): Invalid line - direction vector has zero length"
[P6]
(#711) (Same as 696) Texture loading failed. The texture bitmap files couldn't be opened. This bug was introduced in OIV405.[P6]
(#713) InvQt405D.dll was linked with the non-debug version of Qt even though the debug version was available. Now InvQt40xD.dll will be linked against qt-mtxxxD if it is available. Otherwise it will be linked against qt-mtxxx. [P6]
(#715) It was not possible to use an absolute path in an SoImage node. This bug was introduced in OIV405. [P6]
(#716) ivfix incorrectly weeded out a material node during the process of simplifying the scene graph. [P6]
(#719) Calculated normals were sent to OpenGL for SoIndexedTriangleStripSet shapes that had normals, texture coordinates, and materials specified per vertex. The supplied normals (rather than the calculated normals) should have been used. [P6]
(#720) SoSelection failed when selecting lines with a large zoom and an orthographic camera. [P6]
(#721) For a large viewport (3000,1000), the BigImageRender example produced erroneous output. [P6]

Patch 5: Bugs fixed as of November 10, 2003

(#272) MPEG output had quality defects (moire effects and blocky output) even when the highest output quality was requested (setBitPerSec set to -1 and setCompressionRate set to 0). [P5]
(#373) SoMPEGFrameRenderer::recordFrame consumed a large amount of memory in a multi-thread environment. [P5]
(#538) SoBigImageRenderer did not render a scene with PoSceneView correctly. [P5]
(#602) [Win32] The QtLargeModelViewer project file (.dsp) wasn't provided in the OIV 4.0 distributions. The file was missing from the directory %OIVHOME%\src\Inventor\examples\Qt\QtLargeModelViewer.

By default, the project for VC 6.0 is set up to use Qt 3.1.1. The projects for VC 7.0 and VC 7.1 are set up to use Qt 3.1.2. You may need to change them to use the version of Qt that you have installed on your system. [P5]
(#603) The SoOffscreenRenderer::writeToBMP images didn't precisely match the requested dimensions. [P5]
(#617) The toggleCameraType method was broken in SoXtViewer, SoQtViewer, and SoWinViewer. When the toggleCamera button was pressed on the viewer, the program crashed. Once that was fixed, it was found that if the camera wasn't in a nodeKit, the camera was never set. [P5]
(#639) The same windingType parameter was defined in SoShapeHintsElement and SoGLShapeHintsElement headers. A warning message was generated (at least on Solaris) during compilation:

SoGLShapeHintsElement.h", line 79: Warning windingType hides SoShapeHintsElement::windingType.

[P5]
(#642) SoSwitch caused SoSearchAction to return duplicate paths. If you did this:
```
  SoSearchAction sa;
  sa.setNode( pNode );
  sa.setInterest( SoSearchAction::ALL );
  sa.setSearchingAll( TRUE );
```
and pNode is an SoSwitch, the SoSearchAction would return two identical paths for every instance of the node. [P5]
(#645) The application crashed when using octree ordering and interacting with embedded draggers. [P5]
(#657) SoVRMLSound didn't work in OIV 4.0.4. [P5]
(#660) If an SoTexture2's filename or VRMLImageTexture's url was file://c:etc, the file could not be found. For example, if the url was file://c:/globe.rgb, the program couldn't find the image file. If the url was c:/globe.rgb, the file could be found. [P5]
(#661) MPEGRenderer crashed when several movies were built. The crash didn't occur in one of the SoMPEGRenderer methods but later in the method SoWinRenderArea::render because of a ref count problem. [P5]
(#663) [Win32] The SoWin::threadInit methods call SoInteraction::init, but not SoInteraction::threadInit. Meaning that multi-thread setup for draggers and manipulators was not being done. [P5]
(#664) SoQt was missing its threadInit methods. [P5]
(#667) There was a symbol conflict between INV400.LIB and MSVCRT.LIB when using VC7.1. Both libraries had the symbol (??_M@YGXPAXIHP6EX0@Z@Z). This forced the link order to become important. The problem may be due to using STL. The problem does not occur with the Mentor examples. [P5]
(#671) The IVF AppWizard for VC 7.1 didn't work. When attempting to create a new project, the error was:

"Object with program ID VsWizard.VsWizardEngine cannot be created."

Several Wizard files were updated. See the release notes for information on copying the updated files to the correct location in your VC++ 7.1 installation. [P5]

Patch 4: Bugs fixed as of September 24, 2003

(#539) SoXtGLWidget did not allow the user application to get control before a redraw triggered by an expose event. exposeCB now calls the new methods onExpose and onOverlayExpose. These methods are protected and virtual, which allows them to be overridden in a custom viewer subclass. [P4]
(#550) (SGI) Switching between OpenGL (raw) stereo and mono viewing on SGI caused the scene to disappear if OIV_NO_OVERLAYS was set. [P4]
(#566) (Linux) Open Inventor did not clear overlays using NVIDIA cards on Linux because the wrong value for the transparent pixel was being used. [P4]
(#591) (SoQt) SoEventCallback returned an invalid button number when mouse buttons 2 and 3 were pressed. [P4]
(#595) When using addFunctionKeyBinding to do camera translation, the initial location was not initialized, which caused the scene to disappear unexpectedly. This behavior could be seen using the SetKeyBinding example in the Features directory. [P4]
(#598) (SGI) The StereoDialog "raw" (OpenGL) stereo choice was sometimes incorrectly grayed out on SGI. [P4]
(#599) Duplicate of 595. [P4]
(#600) New feature: SoViewingReverseDolly, derived from SoViewingFunction, works like SoViewingDolly, but opposite. That is, mouse move up corresponds to "zoom-in" and mouse move down corresponds to "zoom-out". [P4]
(#609) During an SoCallbackAction traversal, if a Material node set the transparency to a non-zero value, subsequent Material nodes could not set transparency (in the state) back to zero. [P4]
(#635) Picking an invisible NURBS curve caused the application to abort. [P4]
(#638) Uninitialized variable in SoGLLazyElement (internal) caused opaque objects to be transparent. [P4]

Bugs fixed in patches 1, 2, and 3

(#447) Fast and Best interlaced stereo modes gave very slow performance on NVIDIA boards.
(#466) SoExtSelection failed in VISIBLE_SHAPES mode and with non-convex lasso. Shapes could be selected by the SoExtSelection even if they were not surrounded by the lasso. It only occurred if the lasso mode was set to VISIBLE_SHAPES.
(#469) On some systems, the SoVRMLSound node caused the application to crash.
(#477) The viewer decorations were drawn incorrectly if the SoQtExaminerViewer (or other viewer) was built with SoQtFullViewer::BuildFlag::BUILD_POPUP (which means to display the viewer without decorations initially).
(#479) Backslashes couldn't be used in Inventor/VRML files in filename specifications. (There was no problem using backslashes in file names specified programmatically.)
(#483) The TreeView demo program didn't find texture/image files that were specifed in files that were drag and dropped. (Files that were opened viaFile->Open worked fine.)
(#487) Setting Anaglyph stereo changed the background color. For example, if the Anaglyph stereo color is red-cyan and the background color is yellow, the background turned red because the glClear was called after the colorMask had been set to red and alpha only.
(#489) The background color showed through at the top of the stereo property sliders.
(#490) SoQt: After a window was made full screen, when it was made NOT full screen, the window contents were not resized and the decorations were lost.
(#496) Duplicate of #514.
(#514) There was a 16-byte memory leak in all elements derived from SoReplacedTextureElement (internal). This leak could potentially affect any action that could be applied to a scene containing a texture and any shape to which a texture could be applied. Although the leak was small, it could occur often enough to cause a problem.
(#517) SoCollisionManager was displaying significantly different collision results for release and debug builds. The release results were incorrect.
(#520) SoCollisionManager had a memory leak. The ref count of certain objects went up each time the Collision Manager was created, and it didn't go down when the Collision Manager was destroyed.
(#527) Using SoQt, in an eventCB of type SoKeyboardEvent, when a keyboard key was held down (auto-repeat), the callback function was called with a sequence of both keydown and keyup events. This is normal behavior for Qt, but Open Inventor programs expect a single keyup event when the key is released.
(#528) OGLInfoUnix.cxx always reported that a direct connection was available.
(#529) SoXtColorEditor.h could not be included on MS-Windows. The compilation failed because it was unable to open <Xm/Xm.h>.
(#530) 2D text in SoBigImageRenderer was incorrect for all but the first tile.
(#534) The SoVRMLBackground node was not passed through SoToVRML2Action. If your initial scene graph contained an SoVRMLBackground node, and you converted the scene graph to VRML2 using SoToVRML2Action, the VRMLBackground node was lost in the conversion process. The error message was: ERROR: Do not know how to treat the class VRMLBackground. The node will be lost in the output.
(#540) Memory leak in SoToVRML2Action. When a big shape (SoTriangleStripSet) was exported to VRML2, there was a (big) memory leak. There was no memory leak in SoToVRMLAction.
(#544) TIFF import didn't correctly load the RGB components on big endian machines.
(#546) SoMarkerSet didn't work with SoOffscreenRenderer. Only one marker was displayed.
(#549) Using SoQt, mouseMove events were only sent to the viewer event callback while a mouse button was pressed. This is normal behavior for Qt, but Open Inventor programs expect to get mouseMove events whenever the cursor is in the Open Inventor window.
(#551) The method SoPreferences::getBool returned the opposite of the value set by setBool.
(#559) The SoVRMLMovieTexture node did not know how to deal with relative paths. If you did a readFile using a relative path name, and the file contained an SoVRMLMovieTexture, the movie texture file was not found.
(#574) SoExtSelection crashed when the rectangle lasso was enabled on Qt viewers.
(#581) There was a problem with caching and transparency. An object was incorrectly rendered as opaque after switching between various draw styles (hidden line, wireframe, etc.)
(#582) After an object's attributes (transparent, opaque) were changed several times, the object was not drawn with the correct transparency. This problem was related to caching. If an object was cached while it was opaque and then its transparency changed, (and rendered delayed), the cache should have been broken but wasn't. If you turned off render caching, problem went away. Note: Although superficially this bug resembles #581, it is different.
(#588) Draggers behaved badly when coordinates in scene were very large. This could be seen when adding a light (e.g., using SceneViewer) to a scene with very large coordinates. The light manipulator behaved erratically.

OFFICIAL RELEASE: Bugs fixed as of April 8, 2003

(#5) If an .iv file already contained VMRL2 nodes, they were lost when the file was converted to VRML2 format. Now they pass through the conversion process unchanged.
(#7) (Enhancement) You couldn't query the current stereo mode using the SoViewVolumeElement. Use this method defined in SoStereoElement: const static SoCamera::StereoMode getStereoMode(SoState *state);
(#25) VRML ROUTEs were not processed if they occurred inside of a node definition.
(#33) SoCollisionManager problems fixed. Crash in SoCollisionManager constructor on large scene (30x24x12 cubes). Also, bad initialization of the transformation in SoCollisionManager after collision.
(#44) (HP using OpenGL) The SoOffscreenRenderer writeToJPEG and writeToPostScript methods used to output black images if multipass antialiasing and/or sorted transparency was ON.
(#65) [UNIX] The visual selection code never asked for stencil buffers.
(#67) A textured NURBS Surface couldn't be selected (the selection and pickFilter callbacks were never called).
(#103) The SoOffscreenRenderer::render method crashed on Linux Redhat 7.1.
(#114) [UNIX] If you closed and reopened the stereo preferences dialog, it didn't remember the previously requested stereo type.
(#119) (NuTCRACKER) Open Inventor didn't correctly handle spaces in the env var SO_DRAGGER_DIR.
(#122) (Solaris) Raw stereo item appeared to be selected initially, but you had to re-select it after enabling stereo for it to take effect.
(#124) (IVF) Exiting an IVF app after pasting from the clipboard caused a debug error "Child Index -1 out of range".
(#128) Deleting all instances of a PROTO or EXTERNPROTO caused their definitions to be deleted. An application would no longer be able to use those definitions.
(#130) The SoTexture2 node was not converted to VRML2 by SoToVRML2Action.
(#131) (IVF) When an Inline node was added to the pending queue, it was ref'ed but not unrefed when taken out of the queue. This caused a memory leak.
(#132) (Win32) The Manual mode of the Material Editor did not update the display. If the Update Frequency of the SoWinMaterialEditor class was set to SoWinMaterialEditor::AFTER_ACCEPT, the display wasn't updated by pressing the Accept button.
(#150) Help button in viewers used to look for Inventor.hlp, which is no longer delivered. Now it looks for RefMan.chm.
(#152) The BLEND mode of texture nodes didn't support images having more than 2 components.
(#158) The SoCollisionManager didn't trigger its collision callback if the transformation was of type SoTransformManip and if its fields were modified by hand.
(#164) The method SoMPEGNavRenderer::setSceneGraph didn't work. The SoMPEGNavRenderer::record method failed (nothing was recorded) on a scene set by the setSceneGraph method. The record method worked on the same scene if the scene was used as parameter of the SoMPEGNavRenderer constructor.
(#172) The SbViewVolume::projectPointToLine method didn't correctly map a 2D point to a 3D line in a non-square window.
(#178) A subtexture applied to a texture that is not a power of 2 was displayed incorrectly.
(#186) SoOctreeOrdering did not return the correct bounding box. The consequence was that the octree was cut by the near and far planes when drawn.
(#188) The SoExtTexture2 node wasn't converted into VRML or VRML2 format.
(#191) The license checker had a hard-coded limit of 32 licenses. Above 32 licenses, it failed ungracefully. Limit is now 100.
(#192) Changing the number of vertices in an SoVertexProperty node did not break the associated normal cache. Consider a QuadMesh with its vertexProperty field initialized with an SoVertexProperty node. Later, the number of points in the vertex array is changed. The normals should be but are not automatically regenerated. The result is a mismatch between the number of vertices and number of normals. In debug mode, lots of errors are generated. Ultimately, an incorrect picture was drawn.
(#195) Conflict between Po3DdataPrivate.h and SoG5GNurbs.h. They both defined Point3, resulting in a compile error. You could run into this problem if you tried to use TerrainViz and DataViz in the same app, or NURBS and DataViz together.
(#206) The SoBitmapFontCache destructor freed (by C++ delete function) a pointer allocated by C malloc (in libFL).
(#207) Large FaceSets crashed on NuTCRACKER.
(#208) There was a memory leak when large LineSets were removed from and then re-added to the scene.
(#209) Large TriangleStripSets crashed on NuTCRACKER.
(#210) Large IndexedTriangleStripSets crashed on NuTCRACKER.
(#211) System fonts weren't displayed on Linux (fixed by using a new libGLU).
(#212) Indexed shapes caused memory leaks when the coordIndex and vertex fields were modified.
(#214) A NURBS shape of degree 1 was unpickable with SoRayPickAction.
(#219) Memory leak on SoTexture2 node management. If you inserted, then deleted, then inserted, ... a SoTexture2 node to/from a scene, there were memory leaks.
(#221) (IVF, VisualStudio .NET) SceneViewer (and other IVF apps) built with VC 7 could not read .iv files that contained TRUE or FALSE values, e.g., solid TRUE.
(#226) Patterns and SCREEN_DOOR transparency broke the render cache, causing reduced performance.
(#227) OIV 3.1.1 textures used much more memory (x2-3) than OIV 2.6. There were performance and memory problems related to texture management.
(#229) IndexedLineSet crashed on NuTCRACKER 7.5 when too many indices were used.
(#230) (HP-UX) The license manager sometimes failed because it failed to get a hostid.
(#232) SoExtTexture2 export problems. If the loadStatus field was written to the iv file with value TRUE, when the file was loaded, the texture was considered as loaded and the delete of this texture crashed.
A similar problem occurred with the field loadingMode (when set to MANUAL). When the file was loaded, the texture wasn't displayed.
(#237) Mentor examples 17.2 and 17.3 missing missing from the OIV 3.1.1 for Windows installation. (Note: 17.1 is intentionally omitted because it has not been ported to Windows.)
(#246) The methods addChild and insertChild of the class SoGroup were not declared as virtual, preventing subclassing in some cases.
(#247) A manipulator above a VRMLBillboard node caused the geometry under the VRMLBillboard to be displayed incorrectly. The transform introduced by the manipulator caused the VRMLBillboard to not stay screen-aligned when the screen-aligned case was requested.
(#248) When a window was destroyed, its handle (stored internally in SoWin) was not set to NULL. This could cause a program crash when trying to open a second window.
(#249) The PNG import used too much memory.
(#252) Memory leak when SoDB::setNumRenderCaches was set to 0.
(#253) SoInput::addEnvDirectoriesFirst added directories to the search list twice.
(#255) The SoExtTexture2 node crashed (or went into an infinite loop) if the image file wasn't available.
(#257) Selection failed on geometry described with very small coordinates (around 10e-006). An environment variable, OIV_INTERSECT_EPSILON was added to allow specification of a smaller epsilon to allow these very small shapes to be picked.
(#259) WWWAnchor node with no children crashed SceneViewer when trying to view anchors (viewPoints menu).
(#268) Picking performance was slow in multi-thread environment.
(#269) SoXtFullViewer and SoXtMPFullViewer were missing the getStereoDialog and setStereoDialog methods.
(#270) IVF crashed in IvfImportDocument if IvfImportDocument was called when there was no scene graph in the doc class (i.e., m_pSceneRoot was NULL).
(#273) SoDecimationXXElements classStackIndex link error (prevented applications from using these elements).
(#275) The threadInit() method crashed in an ActiveX application. The SbPList registeredClassList was not protected by a mutex and caused a crash when the list was expanded while another thread was using the list.
(#279) In the Open Inventor VC7 installation, Open Inventor directory names were sometimes put into the VC7 directory list(s) incorrectly. Specifically, the Open Inventor directory name was sometimes concatenated with the last name in the list, rather than being given its own listing. This resulted in Open Inventor projects not building because the necessary Open Inventor files were not found.
(#280) The SoReorganizeAction::apply method failed when the reorganized scene root included only one child (non Separator).
(#281) The SoCollisionManager didn't work on SoTransformManip nodes if you modifed by hand the fields of this node.
(#288) SoFieldContainer::m_userData needed to be initialized to NULL. Also, the getUserData method of this class was made "const".
(#291) (Win32) Material Editor: If you attached a material and then showed the editor, the material editor did not display the attached material.
(#293) SoText2 strings were not correctly clipped at the left and bottom edges of the window. For a default left-justified SoText2 string, if the left edge of the string was moved outside the window, the entire string disappeared. This was very noticeable using the multi-pipe viewer because SoText2 strings that began on the left display should continue across the boundary onto the right display, but appeared to be "clipped" at the display boundary. Also seen in CAVELib apps.
For compatibility with current caching behavior, user must define environment variable OIV_CLIP_TEXT2 to get the new behavior.
(#299) If you used an SoImage node inside a PoView (or PoSceneView) the shape was not clipped against the specified view port.
(#305) Ref counts of the SoExtSelection node and the shapes increased each time SoExtSelection was called.
(#306) Most of the SoGroup methods weren't virtual. This meant that if one made a list of SoGroup pointers and put SoVRMLTransforms in it, the wrong addChild was called.
(#309) The SoOffscreenRenderer methods writeToJPEG and writeToTIFF did not delete the internal buffer correctly.
(#310) SceneViewer and TreeView crashed when an iv file that included an invalid SoTexture2::filename field was loaded.
(#313) The SoGLRenderAction::setUpdateArea didn't work. This method sets a GLUpdateAreaElement in the traversal state, which results in a call to glScissor to set the new area BUT the glEnable(GL_SCISSOR_TEST) was never called.
(#316) SoExtSelection selected objects that were behind the camera viewpoint.
(#321) SoCollisionManager failed when the path of the object was built by the SoPath::copy method.
(#322) There was bad precision on collision detection (even when SHAPE mode was used). The collision manager apparently stopped on "virtual" bounding boxes. It didn't stop on the shapes themselves.
(#325) The default OIV Suite download bundle nows include the material files for the Material palette.
(#326) Patterns were sometimes applied to the wrong shapes. Shapes that were defined in a graph before SoPattern or in another Separator were sometimes displayed with the pattern. This occurred when the scene moved (the initial display was correct).
(#328) (Enhancement) Material Palette Dialog: Colored spheres are now displayed with a higher quality transparency type (not screen door).
(#330) The VRMLTouchSensor did not activate the VRMLTimeSensor to drive the VRMLColorInterpolator when inside a PROTO.
(#331) (IVF) If a PoSceneView node included two SoTexture2 nodes loading the same file, the display wasn't textured.
(#335) The start/finishEditing methods didn't rescale textures. If the SoSFImage field of a texture node was updated between start/finishEditing calls, the texture was incorrectly displayed (this texture wasn't rescaled).
(#336) The error "SoPath::removeIndex(): Can't find parent node error" occurred erroneously. If you changed a node at the tail of a path that was created by searching for any node used a field used in an SoVRMLAppearance node, the program would generate the error, then crash.
(#338) Assertion problem in the demo SlotCar. The line:
assert(newTime > currentTime);
was replaced by:
assert(newTime > = currentTime);
(#339) The incorrect texture was displayed using JPEG export (SoOffscreenRenderer method writeToJPEG) when SoTexture2 and SoExtTexture2 nodes were mixed in the same scene.
(#359) (Linux) Open Inventor crashed when the stereo dialog box was closed with the X button.
(#364) The scale and shift operations of a SoTransformerManip class became incorrect if an SoUnits node was included in the manipulated scene.
(#369) The SoMPEGFrameRenderer::recordFrame method crashed when setFilePointer was called.
(#370) SoMPEGRenderer::getFilePointer returned an invalid file descriptor when openFile was called to open the MPEG file.
(#378) SoManipulator could initially fail to get the correct bounding box for geometry in SoWWWInline.
(#379) There was a memory leak when highlighted objects were animated (spun).
(#381) The VRMLTimeSensor did not send a final value of 1.0 when loop was FALSE at the end of the cycle.
(#388) Switching to DOLLY mode from PAN using the CRTL SHIFT caused the scene to jump.
(#389) Picking problem with SoMarkerSet, SoPointSet, and PoScatter within a PoSceneView. Using SoSelection node under two different PoSceneViews with pick filter callbacks attached, caused some pick filter calls however the point primitive (SoMarkerSet, SoPointSet, or PoScatter) was not selected.
(#392) SoIntersectingPrimitive detected a collision between a sphere and cone when there an intersectio of the bounding boxes, but not their geometry.
(#395) SoExtSelection crashed when the setTriangleFilterCallback set a user callback. This crash occurred in SbPlist even if the user callback did nothing.
(#396) TreeView program hung or immediately exited when loading a scene graph containing a node with a very long string in the string field.
(#405) SoMarkerSet::addMarker crashed when called on predefined indices without preliminary rendering.
(#416) SoMarkerSet didn't display markers in an MDI application when all documents were closed and then reopened.
(#420) (Enhancement) A new SoEXTENDER method clearOtherEventCallbacks() was added to SoDragPointDragger to allow suppression of the Ctrl-key behavior in SoJackDragger. Customer wanted to suppress the Ctrl-key behavior in SoJackDragger (switches to a different translation axis) because only one axis is valid and this behavior could confuse the user.
(#425) Some geometry was not displayed because VRML inlines were not processed properly.
(#428) The Save button of the LargeModelViewer demo emptied the currently loaded file. The button was removed.
(#429) IVF programs could not set the default camera type. Normally an Inventor app can call SoWinViewer::setCameraType to specify whether an orthographic or perspective camera should be created if the scene graph does not contain any cameras. IVF overrides this feature and *always* creates a perspective camera. There is now a new method, CIvfDocument::setCameraType, equivalent to the SoWinViewer method.
(#430) There was a memory leak in SoIndexedShape.
(#433) There was a memory leak in the method SoReadImage::ReadJPEGImage.
(#440) In the IVF AppWizard, the SceneViewer option is now disabled if you are building a dialog-based app (because this combination of options is not meaningful).
(#444) If the from connection of a VRMLinterpolator wasn't an output of the Interpolator but from an exposedField that has an implied eventOut, the connection didn't work and a debug error was issued.
(#446) SoReorganizeAction (ivfix) had a problem when the material transparency field was NULL. In addition to the fix, various optimizations were added.
(#459) SoTransform::multLeft caused deadlock when SoDB::writeLock has been called.
(#462) During construction of an SoPickedPointList, the SoDetailList->copy was not copying NULL pointers that were in the SoDetailList, causing the SoPickedPointList constructor to be incomplete.
(#468) VRML files fitting the following profile could cause Open Inventor to crash:
- They contained multiple SoVRMLIndexedLineSets,
- AND the first line sets had fewer lines than subsequent ones,
- AND the colorIndex field was empty,
- AND the colorPerVertex field was FALSE.
The same problem could also occur with SoVRMLIndexedFaceSets.

Open Inventor 3.1.1

An Indexed LineSet was (sometimes) drawn in the wrong color. (#104)
SoExtSelection: When lassoPolicy= FULL_BBOX, sometimes a stroke font string was selected when it should not have been. (#106)
When text was selected with SoExtSelection, the red highlight box was offset from the text string. (#107)
A particular text string could not be picked in SceneViewer. (#108)
Setting values in SoVertexProperty, orderedRGBA field was too slow. (#134)
In wireframe mode, one patch of the OctreeAndSplitAction example was drawn in the background color. (#136)
SoText2 did not honor the requested font on Windows . It used the default font. (#137)
The global simplifier failed on boundary shape having a least 3 aligned points. (#138)
SoFile::search method did not check if the search was for SoFile nodes. (#143)
SoWinKeyboardEvent did not handle punctuation characters. (#153)
The SbTime.h file prevented the use of the C++ max function on Windows. (#157)
Picking a line in a line set did not work with SoExtSelection unless the line was the first when PART set. (#159)
Objects described by SoTriangleStripSet or SoIndexedTriangleStripSet nodes was smoothly shaded even if the creaseAngle was set to 0 to get a sharply faceted object. The environment variable OIV_CREASE_ANGLE_FIX must be set to be able to use this fix.(#170)

Open Inventor 3.1

Patterns and transparency conflicted. Now pattern fill takes precedence over screen door transparency. (#4)
SoBigImageRenderer: If you used the constructor that takes an action as input, the viewport dimensions specified in the GLRenderAction were ignored. (#10)
SoExtSelection didn't pick a line segment unless a vertex of the line segment was inside the lasso. (# 11)
When an object had a pattern, the pattern was not initially displayed until the object had been interacted with in the viewer. (#12)
If SoLabel had a label field that was NULL, when you tried to read it in a file, OIV issued an error message. (#14)
Various empty VRML primitives caused the OIV viewers to crash. (#15)
If the 3D texture supplied did not have power-of-2 dimensions, the program crashed. (#16)
inttypes.h had defines that conflicted with customer's include file. (#17)
If a .wrl file had an empty index array, the OIV viewer crashed. (#18)
The Question Mark character "?" was not defined for SoKeyboardEvent. (#20)
The licensing error message produced when an RT license was used in an SDK environment was incorrect. Licensing error messages in general are more informative. (#21)
SceneViewer crashes upon exit after displaying .wrl file containing ElevationGrid. Fixed in SoVRMLGridShape's destructor. (#27, #35)
When a specific PROTO name was declared on an EXTERNPROTO url, only that PROTO was read from the file. If the requested PROTO used other PROTO's preceding it in the file, they were not read in and the program crashed. (#28)
When a field of a PROTO contained an SFNode or MFNode, it was not instanced correctly. When the SFNode or MFNode was itself a PROTO, the default value was not set correctly.
Open Inventor ended up thinking it was an unknown node. (#29)
Deleting all values of an SoMFPath caused an assertion debug and then a crash. (#31)
The SoExtSelection class crashed when the lasso surrounded a pickable shape outside the extSelection branch. (#32)
The SoToHTMLAction class produced JPEG files that were way too large (because a .bmp image was tacked on the end). (#42)
Open Inventor for SGI didn't support 3D textures. (#50)
SoExtSelection didn't work when PoSceneView nodes were defined in the scene. (#59)
The SoDragPointDragger entered an infinite loop in debug mode when the camera and the dragger's cylinder are aligned with the same axis. (#64)
Seek didn't work right in raw stereo on Solaris.The camera moved far closer than one-half of the distance. (#66)
Missing default last argument of the method SoIntersectionDetectionAction::apply(...,SbBool obeysRules).
This argument was missing from other apply methods as well. (#69)
Removed the explicit calls to glTexImage3DEXT and glTexSubImage3DEXT from the SoTexture3 class. This was a portability problem. (#73)
The Latin 1 characters weren't displayed on UNIX. (#74)
SoLineHighlightRenderAction sometimes highlighted too much. (#79)
Some geometry was not displayed because VRML inlines were not processed properly. (#87)
When Inlines are not loaded immediately, and there are duplicate inline URL's, geometry is left out. (#89)
Negative values of OIV_FORCE_PIXEL_FORMAT only worked if OIV_DEBUG_PIXEL_FORMAT was set. (#93)
The vertexProperty node didn't manage the PER_FACE material binding properly if the faces included more than 3 points and the ShapeHints::faceType field was set to UNKNOWN_FACE_TYPE. (#97)
The SoWinViewer method getAntoClipTolerance needed to be renamed to getAutoClipTolerance. (#102)
The RedGreenStereo example didn't activate stereo display. (#105)
Open Inventor 3.0 applications could not run on Win95. The error message was: The INV300.DLL file is linked to missing export KERNEL32.DLL:SignalObjectAndWait. (#113)
Picking an object using box highlighting changed the aspect ratio of the displayed scene. Most visible in very non-square windows. (#115)

Open Inventor 3.0

The problem of loss of accuracy when an SoCoordinate3::point field was written has been corrected (TEBUG 0260005).
The crash on certain NURBS curve shapes with knots having multiplicity greater than the degree of the NURBS has been fixed (TEBUG 0260011).
When the SoToHTMLAction was applied to a scene containing an SoAnnotation node, the output HTML file was incorrect (TEBUG 0260012).
When an SoEngineOutput of type SoSFPath was connected from a field of the same type, Open Inventor crashed (TEBUG 0260025).
The lasso mode of the SoExtSelection node did not always highlight the selected points when the window was maximized (or at least resized). Also some points were highlighted that were not inside the lasso (TEBUG 0260028).
It was impossible to display characters with accent marks with stroke fonts. A new static method SoFont::enableTGSJapaneseSF() has been created (TEBUG 0260019).
The output from SoOffscreenRenderer::writeToxxx() was incorrect (TEBUG 0260035).
The SpaceBall was not usable with IVF and MFC applications on Windows (TEBUG 0260033).
In SoExtSelection with lassoPolicy = PART and lassoType = RECTANGLE, a shape was not selected if the vertices were outside the lasso but the lasso crossed the shape.
On Linux, SoCalculator had an accuracy problem (TEBUG 0260009).
On Linux, inttypes.h and stdint.h define the types intptr_r and uintptr_t differently. This problem has been solved (TEBUG 0260034).
A crash occurred on Solaris (and probably on other platforms) when displaying stroke fonts with ASCII code > 127 (TEBUG 0260018).
A memory leak in SoOffscreenRenderer on UNIX platforms was fixed (TEBUG 0260032).
SoXtColorEditor class is now available for UNIX versions (TEBUG 0260042).
Raw stereo (OpenGL) on UNIX has been broken since version 2.6.1. Now fixed (TEBUG 0260016).
When writing a TIFF file, the application is responsible for opening and closing the file. But Open Inventor was closing it. Fixed. (TBUG 3158)
Textured NURBS were not displayed correctly (TEBUG 0260004).
If an SoText3(or SoAnnoText3) node was instantiated twice in the scene graph as follows:
- stroke font
- text node
- non stroke font
- second use of the same text node
both text strings would be rendered with the stroke font.
The viewer decorations were not being turned off when requested.
Fixed a problem with nodekits. If a scene graph containing nodekits was written out and then copied, the resulting scene graph contained errors. (TBUG 3169)
Changed the enum named BM_FileType and its enumeration identifiers (BM_FILETYPE_UNKNOWN became UNKNOWN, and so forth) to be more consistent with Open Inventor naming conventions.
This name change affected SoTexture2, SoTexture3, SoExtTexture2, SoVRMLImageTexture, SoVRMLMovieTexture, and SoVRMLPixelTexture.
Made all the methods and member variables in class SoSceneViewer public as they were in Open Inventor 2.1.
Added an epsilon to SoNormalGenerator so that coordinates very close to zero do not cause a crash. (TBUG 3167)
AsciiText disappeared when drawn in wireframe because it doesn't support OutlineText but SoOutlineFontCache enabled it by default (TBUG 3162).
In SoExtSelection, the lasso drawn in the overlay planes now has the correct position on the screen when the window is not square (TBUG 3161).
In SoBigImageRenderer, the constructor that takes the action as an argument did not extract the viewport values from the action and set them in the renderer (TBUG 3166).
Added some missing #defines in SoXt2SoWin.h (TBUG 3164).
After reading in a TIFF texture file, Open Inventor did not close the file. Then the user could not open it (TBUG 3163).
Fixed a problem with antialiasing and blended transparency that caused a line to be wider than it should be (TBUG 3160).
Fixed picking NURBS curve object problem.
Use the latest version 1.13 of ZLIB.
Fixed SoCollisionManager with empty SoPointSet.
SoExtSelection correction/optimization for picking an SoPointSet.
Fixed LargeModelViewer crash if there was no license.
Fixed LargeModelViewer crash with Inventor files containing NURBS.
Added new method IvfIsInlinesPending() to the IvfDocument class to determine when there were no more Inlines pending. (Window only)
(Enhancement) Added new methods to SoIntersectionDetectionAction so that the epsilon that determines how close to check for
