Detailed Description
Manages Open Inventor configuration parameters.
Open Inventor maintains a configuration database that stores information about the Open Inventor "environment". The Open Inventor environment contains configuration parameters and their values.
Setting configuration parameters
There are several ways that configuration parameter values are set into the Inventor configuration database:
Configuration files: When Open Inventor is initialized, two configuration files are automatically read (if available):
- A system configuration file $OIVHOME/oiv.cfg or the file pointed to by the OIV_CONFIG_FILE environment variable, and
- a local configuration file named oiv.cfg located in the application's current working directory.
The configuration parameters specified in the configuration files are set into Open Inventor's configuration database.
You can request that additional configuration files be read using SoPreferences::readFile.
The configuration file format is simple. You specify environment name-value pairs, one per line. The file format is shown below.
Using SoPreferences methods: SoPreferences::setValue sets a configuration parameter in the Open Inventor configuration database. As this value is set in memory, it is local to the application process and can only be retrieved using SoPreferences::getValue. There are convenience methods available for setting specific values of a specific data type, e.g., setFloat.
Using system environment variables: If a particular configuration parameter has not already been set via a config file or setValue, then Open Inventor will check the system environment. System environment variables are set using platform-dependent commands (e.g., set, setenv).
Querying configuration parameters
To query a specific configuration parameter, use the method SoPreferences::getValue which returns the value of the specified configuration parameter in the Open Inventor configuration database.
SoPreferences also provides convenience methods for querying specific data types and providing a default value, e.g.,
int numFiles = SoPreferences::getInt( "NUM_FILES", 1 );
requests the value of an integer-valued configuration parameter and returns the default value 1 if this parameter has not been specified. Corresponding "set" methods are also provided.
Other
The SoPreferences configuration mechanism is not restricted to Open Inventor parameters. Applications are welcome to use it for their own parameters if appropriate.
To request configuration debugging information, use environment variable OIV_DEBUG_CONFIG.
White space (blank, tab) is ignored, except that there must be at least one space or tab separating the name from its value.
System environment variables may be used in a configuration file. Environment variable names begin with a $ and end at the next nonalphanumeric character. They are replaced by their corresponding value.

DIRECTVIZ_NUM_THREADS_SLAVE
Affects DirectViz. When a multi-processor or multi-core machine is used as a slave in a cluster configuration, specifies the number of threads per slave. The number of threads should correspond to the number of processors possibly multiplied by the number of cores of each processor; otherwise there may be some unnecessary overhead. Default value is 4.

DIRECTVIZ_PROGRESSIVE_RENDERING
Affects DirectViz. If set to 1, enables progressive rendering. The value can be set programmatically using the SoDirectVizManager::progressiveRendering field. Default value is 0.
DIRECTVIZ_RECURSION_LIMIT
Affects DirectViz. The recursion limit is the maximum number of times that a ray can "bounce" within the scene when rendering a frame. The higher the recursion limit is, the more accurate the scene appears. The value can be set programmatically using the SoDirectVizManager::recursionLimit field. Default value is 20.
DIRECTVIZ_RENDER_STEPS
Affects DirectViz. Specifies the number of steps between a subsampled render and full rendering. Must be greater than 0. The value can be set programmatically using the SoDirectVizManager::numProgressiveRenderingSteps field. Default value is 5.
DIRECTVIZ_RENDERING_OBJECT
Affects DirectViz. Specifies the DirectViz shader package. See the User's Guide for details. Default value is "RTX".
DIRECTVIZ_SUB_RECURSION
Affects DirectViz. Specifies the recursion depth limit (when sub-sampling is active). The value can be set programmatically using the SoDirectVizManager::subRecursion field. Default value is 1.
DIRECTVIZ_SAMPLES_PER_PIXEL

DIRECTVIZ_SOFT_SHADOWS
Affects DirectViz. If set to 1, enables soft shadows. The value can be set using the SoDirectVizManager::softShadows field. Default value is 0.
DIRECTVIZ_SUBSAMPLING
Affects DirectViz. If set to 1, enables subsampling. Sub-sampling the scene consists of rendering a smaller (i.e., lower resolution) image when the viewer is not still. The value can be set programmatically using the SoDirectVizManager::subSampling field. Default value is 1.
DIRECTVIZ_SUBSAMPLING_FACTOR
Affects DirectViz. Specifies the subsampling factor. Values can range from 0.1 to 1.0 (full resolution). The value can be set programmatically using the SoDirectVizManager::subSamplingFactor field. Default value is 0.5.
FXVIZ_SHADOW_TEXTURE_UNIT0
SoShadowGroup reserves texture unit FXVIZ_SHADOW_TEXTURE_UNIT0 and FXVIZ_SHADOW_TEXTURE_UNIT1 for its rendering. If these values are not set, texture units 1 and 2 are used. These values can't be greater than 3.
FXVIZ_SHADOW_TEXTURE_UNIT1
SoShadowGroup reserves texture unit FXVIZ_SHADOW_TEXTURE_UNIT0 and FXVIZ_SHADOW_TEXTURE_UNIT1 for its rendering. If these values are not set, texture units 1 and 2 are used. These values can't be greater than 3.
IV_ALLOW_LOCATE_HIGHLIGHT
Affects SoLocateHighlight and SoTransformerDragger.
Default is false. If false, locate highlighting (mouse-over feedback) is disabled unless the application explicitly sets each SoLocateHighlight node's 'mode' field to AUTO. If true, an SoLocateHighlight node's mode field is automatically set to AUTO. Effectively locate highlighting for the SoTransformerDragger can only be enabled by setting this variable to true.
IV_AUTO_CACHE_MIN_VALUE
IV_AUTO_CACHE_MAX_VALUE
These influence when automatic caching happens. If set, then shapes with a number of vertices smaller than IV_AUTO_CACHE_MIN_VALUE or greater than IV_AUTO_CACHE_MAX_VALUE will request that their parent separator not use render caching. This can be useful, for example, when creating a render cache for a very large geometry would use too much additional memory.
IV_NO_TEXTURE_OBJECT
Tells Open Inventor not to use OpenGL 1.1 texture objects. If some textures are missing or otherwise displayed incorrectly, try setting this variable.
IV_NO_VERTEX_ARRAY
Tells Open Inventor not to use OpenGL vertex arrays or vertex buffer objects. You can use this environment variable to globally prohibit use of vertex arrays and VBOs. The default is false. Note the "double negative" name. False means that vertex arrays and VBOs are allowed. In most cases there is no reason to set this variable except possibly to test performance without vertex arrays or in the unlikely event that there is a serious bug with the VBO implementation in the current driver/GPU.
IV_OCTREE_MAX_DEPTH
Affects SoOctreeOrdering.
Specifies the maximum depth used during octree ordering. Default: 8
IV_SEPARATOR_MAX_CACHES [Deprecated]
Deprecated, please use OIV_MAX_CACHES instead.
IV_TIMER_RESOLUTION [Windows only]
Specifies how often Open Inventor's internal clock ticks. Effectively it sets the minimum time between render traversals when animating (including spin animation and animation performed by engines). Make sure the value is less than the time it takes to render one frame of your scene. Default: 10 ms.
IVTUNE_SHOW_INTERNAL_CHILDREN
IvTune should allow user to expand hidden children, for example in draggers and manipulators. Default: FALSE.
IVVR_40_COMPAT
Forces VolumeViz 4.0 compatible behavior. For example, paging mode is the default, slices are not affected by scene graph lights, etc.
IVVR_CHECK_3DTEX_SIZE
Set this config parameter to enable 3D texture size checking for VolumeViz. If the current volume cannot be loaded on the hardware as a 3D texture, a warning is posted and VolumeViz automatically switches to 2D textures to draw the picture.
IVVR_DEBUG
Set to 1 to enable debug trace output for VolumeViz.
IVVR_DELAY_RENDER
Sets the VolumeViz delayedRendering flag.
When this flag is TRUE (1), VolumeViz drawing nodes (e.g. SoOrthoSlice) are considered "transparent" objects by Open Inventor. They may be delayed (until after all opaque objects) and/or sorted according to the current transparency type (see SoGLRenderAction). This may result in a more correct image if there is opaque geometry intersecting the volume. However delayed/sorted rendering may slightly decrease performance. For compatibility with earlier versions of VolumeViz the default is FALSE. This flag may also be set using SoVolumeRendering::setDelayedRendering().
IVVR_FORCE_RAYCASTING
Affects the SoVolumeRender rendering engine. Default is TRUE (use raycasting). Two different Volume Rendering techniques are available:
- Raycasting : default since VolumeViz 9.0. This technique provides more quality and performance in most cases.
- Slicing : used by previous versions of VolumeViz.
IVVR_GPU_PICKING
When this flag is TRUE (1), SoVolumeRender (VolumeViz) will use the GPU to compute the picked voxel color. Default is TRUE.
IVVR_IRREGULAR_TRACE_NUM
Affects SoVRSegyFileReader.
Although in most cases the SEGY reader can automatically detect when the number of traces per line in a SEGY file is not uniform, in some cases it cannot. You can set this environment variable to request the use of a more sophisticated file parsing algorithm. However, be aware that the initialization for file reading will take longer when this environment variable is set.
IVVR_INCONSTANT_TRACE_LENGTH
Affects SoVRSegyFileReader.
Although in most cases the SEGY reader can automatically detect when the length of traces in a SEGY data file is not uniform, in some cases it cannot. You can set this environment variable to request the use of a more sophisticated file parsing algorithm. However, be aware that the initialization for file reading will take significantly longer when this environment variable is set.
IVVR_MAX_NUM_LOADERS
Affects SoVolumeRender.
Specifies the maximum number of loading threads to be used in VolumeViz LDM mode.
IVVR_NUM_LOADERS
Affects SoVolumeRender.
Specifies the initial number of loading threads to be used in VolumeViz LDM mode. Default is 4. This value can be set programmatically using SoVolumeRendering::setNumIO().
IVVR_OGL_CLIPPING
Affects SoVolumeGeometry.
Starting with VolumeViz 6.0, SoVolumeGeometry nodes are clipped using software clipping rather than OpenGL clipping. If you need the version 5.0 behavior, set this environment variable to 1.
IVVR_SEGY_DUMP
Affects SoVRSegyFileReader.
Requests that the file and trace headers be written to a file while processing the SEGY data file. The output file is named ivvrSegyDump.txt in the current working directory. This information may be helpful if the SEGY reader fails to read the file correctly.
IVVR_SEGY_FLOATISIEEE
Affects SoVRSegyFileReader.
If TRUE (1), indicates that floats are written in IEEE floating point format. Normally the SEGY reader is able to detect this, but if necessary you can set this environment variable.
IVVR_SEGY_SWAPBYTES
Affects SoVRSegyFileReader.
Set to 1 to force byte swapping, 0 to force no byte swapping. Normally the SEGY reader is able to detect if byte swapping is needed, but if necessary you can set this environment variable.
IVVR_TF_TEX_UNIT
Affects SoTransferFunction
Allows you to specify the OpenGL texture unit to be used for storing VolumeViz transfer functions. The default is unit 0.
IVVR_USE_TEX3D
Controls when VolumeViz will use OpenGL 3D texturing.
All boards that report OpenGL version 1.2 or higher are required to support 3D texturing and will render the correct image. However on some boards (e.g. GeForce2) this support is not hardware accelerated and may be very slow. By default VolumeViz tries to detect this situation and automatically disable use of 3D textures, but there are cases where it is desirable to use 3D textures even if they are slow. In these cases set IVVR_USE_TEX3D to 1. Valid values are:
- 0 = Never : Do not use 3D textures (even when available)
- 1 = Always : Use 3D textures if supported in hardware or software
- -1 = WhenFast : Use 3D textures only if supported in hardware (DEFAULT)
On some boards, e.g. ATI, WhenFast is the same as Always because we can't reliably detect how 3D textures are implemented.
LDM_USE_IN_MEM_COMPRESSION
Default is true. This environment variable (see SoPreferences) affects more than its name implies. Please read carefully.
VolumeViz always manages data as "tiles", regardless of the data format. In many cases VolumeViz must uncompress or create the tiles at run time. These cases include compressed LDM format files, in-memory volumes, data formats other than LDM (e.g. DICOM or SEGY) and any custom volume reader that does not implement the readTile() method. In the in-memory and non-LDM cases, VolumeViz must create both the full resolution tiles and the low resolution (sub-sampled) tiles.
If this variable is false (recommended for performance), then VolumeViz stores all tiles in the main tile cache, up to the max main memory limit specified using SoLDMGlobalResourceParameters. For compressed LDM data, each compressed tile is uncompressed and the uncompressed data is stored. In this case using compressed LDM data does not reduce memory usage, but tiles in the main tile cache can be quickly accessed and transferred to the GPU. For in-memory and non-LDM data, both full resolution and low resolution (sub-sampled) tiles are stored in the main tile cache.
If this variable is true (the default value), then for compressed LDM data, VolumeViz stores the compressed tiles "as is" in the main tile cache. This allows more tiles to be cached in the same amount of memory. For an in-memory volume or non-LDM data volume VolumeViz only stores the low resolution (sub-sampled) tiles in the main tile cache. In all cases VolumeViz keeps a small number of uncompressed, full resolution tiles in memory in a special "buffer object cache". This memory is in addition to the memory allowed for the main tile cache. See the SoBufferObject method getBufferObjectCache() for the current default buffer object cache size. If a tile's data is needed and that tile is not in the buffer object cache, then the tile must be uncompressed or recreated. This overhead can be significant.
Note:
- We recommend setting this variable to false unless the memory conserving feature for an in-memory volume or compressed LDM data is critical.
- The variable must be set before calling SoVolumeRendering::init().
IVVR_FIRST_RESERVED_TEXTURE_UNIT
Specifies the range of reserved texture units in VolumeViz for various nodes :
- SoVolumeClippingGroup : All texture units between IVVR_FIRST_RESERVED_TEXTURE_UNIT and IVVR_FIRST_RESERVED_TEXTURE_UNIT-2*numPasses are reserved.
- SoVolumeShader : All texture units between IVVR_FIRST_RESERVED_TEXTURE_UNIT and IVVR_FIRST_RESERVED_TEXTURE_UNIT+SoShaderProgramgetNumReservedTextures()-1 are reserved.
If IVVR_FIRST_RESERVED_TEXTURE_UNIT is not set, its default value is SoFragmentShader::getMaxTextureImageUnit()-SoShaderProgramgetNumReservedTextures(). Note the value returned by SoShaderProgram::getNumReservedTextures() may change between versions and must not be assumed constant. Also note the maximum number of texture units depends on the graphics hardware.
IVVR_ALPHA_THRESHOLD_INTERACTIVE
Used in raycasting mode only (the default). Specifies the cumulative alpha opacity) value at which which the ray stops traversing the volume when INTERACTIVE (for example the user is moving the camera). This value should be >= 0.95 to avoid artifacts and must be < 1. A low value increases rendering speed, especially with very transparent volumes but may create artifacts. See also IVVR_ALPHA_THRESHOLD_STILL. Added in version 9.1. Default is 0.95.
IVVR_ALPHA_THRESHOLD_STILL
Same as IVVR_ALPHA_THRESHOLD_INTERACTIVE but in STILL mode. Default is 0.99.
MESHVIZ_OCTREE_CACHE_CELLBBOX
Affects MeshViz.
Specifies if the cell boundingboxes must be cached when building the octree associated to a mesh. This speeds up the search for cells in the octree when using MoMeshPointProbe, MoMeshGridPlaneSlice and MoMeshStreamline nodes, or pointprobes, gridplaneslice and streamline extractors for all kind of meshes (MiPointProbeUnstructured, MiGridPlaneSliceExtractUnstructured, MiStreamlineExtractUnstructured) except regular and rectilinear that do not use octrees.
The default value is 0 (not cached).
MESHVIZ_OCTREE_MAX_CELL_PER_TILE
Affects MeshViz.
Specifies the maximum number of cells that can be contained in a tile of the octree built when using MoMeshPointProbe, MoMeshGridPlaneSlice and MoMeshStreamline nodes, or pointprobes, gridplaneslice and streamline extractors for all kind of meshes (MiPointProbeUnstructured, MiGridPlaneSliceExtractUnstructured, MiStreamlineExtractUnstructured) except regular and rectilinear that do not use octrees.
The default value is 40.
MESHVIZ_OCTREE_MAX_DEPTH
Affects MeshViz.
Specifies the maximum depth allowed to build the octree associated to a mesh when using MoMeshPointProbe, MoMeshGridPlaneSlice and MoMeshStreamline nodes, or pointprobes, gridplaneslice and streamline extractors for all kind of meshes (MiPointProbeUnstructured, MiGridPlaneSliceExtractUnstructured, MiStreamlineExtractUnstructured) except regular and rectilinear that do not use octrees.
The default value is 6.
MESHVIZ_POLYGON_OFFSET
Affects MoMeshRepresentation.
Specifies if surface representations must be automaticallty offset with a SoPolygonOffset node, to allow line representations on top without artifacts.
However SoPolygonOffset can introduce other artifacts on surfaces when the two-sided lighting mode is active. The default value is TRUE (1).
MESHVIZ_TESSELLATION_MAX_DEPTH
Affects MeshViz.
Specifies the maximum depth allowed while tessellating a non-linear cell using the provided implementations of the MiTessellator interface for extractions from quadratic meshes. This parameter makes the tessellation stop once the specified depth has been reached. This prevents from spending too much time in this process. However, the tolerance given by MiEdgeErrorMetric might be not achieved if the maximum depth is low.
The default value is 10 which leads to a maximum of 2^10 = 1024 resulting edges per tessellated edge.
OIV_3DDATA_CREASE_ANGLE
Default value of the field PoMesh::creaseAngle. Default is 0.0. Set the value to 0.8 for compatibility with MeshViz 5.0 and earlier.
OIV_3DDATA_CROSS_SECTION_METHOD
Affects PoMeshCrossSection.
Specifies the method used for computing a PoMeshCrossSection.
- INTERSECTION - The cross section is computed like an isosurface.
- ISOSURFACE - The cross section is computed by doing classic intersections.
Use PoMeshCrossSection::setCrossSectionMethod to specify the cross section computation method programmatically.
OIV_3DDATA_USE_TRIANGLE_STRIP_SET
Affects PoMeshLevelSurf, PoMeshCrossSection.
Specifies the Open Inventor primitive used to draw an isosurface.
- TRUE (1) - a triangle strip set is used
- FALSE (0) - an indexed face set is used
PoMeshCrossSection uses this variable only when the cross section method is ISOSURFACE (see OIV_3DDATA_CROSS_SECTION_METHOD).
OIV_ALPHA_TEST
Affects SoGLRenderAction.
Enables or disables the OpenGL alpha test for rendering. Default is 0 (alpha test is disabled).
OIV_ALUT_NAME
Affects SoDynamicLibManager.
Allows you to use your own ALut dynamic library. Do not add the suffix. Do not add the "lib" prefix on UNIX systems. Do not add the final "D" used in the debug name. Default is "IvDLALut".
OIV_AMBIENT_COLOR
Affects SoEnvironment.
Specifies the default color of ambient lighting. The value is specified as three floats (0.0 to 1.0) representing the RGB values of the color. The value can be set programmatically using the SoEnvironment::ambientColor field.
OIV_AMBIENT_INTENSITY
Affects SoEnvironment.
Specifies the default intensity of ambient lighting. The value can be set programmatically using the SoEnvironment::ambientIntensity field.
OIV_ANTIALIASING_DEFAULT_MODE
Force a different antialiasing method when the default mode (AUTO) is used. Default is SMAA. The preference value can be SMAA, FXAA, FSAA or SUPERSAMPLING.
OIV_AUTO_CLIPPING
Affects SoWinViewer, SoQtViewer, SoXtViewer.
Specifies the default auto clipping flag (0=off, 1=on). The auto clipping flag can be set programmatically using the setAutoClipping method of the viewers classes above.
OIV_AUTO_CLIP_TOLERANCE
Affects SoWinViewer, SoQtViewer, SoXtViewer.
Specifies the default auto clip tolerance (a float). The tolerance can be set programmatically using the setAutoClipTolerance method of the viewers classes above.
OIV_AUTO_INTERACTIVE_MODE
Affects SoSceneManager and therefore the viewer classes, e.g. SoWinViewer, SoQtViewer, SoXtViewer.
Specifies the default autoInteractiveMode flag (0=off, 1=on). Default is false. By default only viewer and dragger interaction will switch the rendered scene in interactive complexity mode. When this option is enabled the sceneManager, based on any notification, will make this decision. It is particularly useful for scenes that have a very long rendering time in STILL mode compared to INTERACTIVE mode (often the case with VolumeViz nodes). An application that automatically triggers animation based on a script (camera path) might prefer to disable this mode in order to keep good rendering quality. This mode can also be set :
- per viewer/sceneManager (see SoSceneManager::setAutoInteractiveMode)
- or dynamically through viewer popup menu->preferences.
OIV_BACKGROUND_COLOR
Affects SoSceneManager, SoWinRenderArea, SoXtRenderArea, SoQtRenderArea, SoMPEGRenderer, SoXtMPRenderArea, SoWinMPRenderArea, SoOffscreenRenderer, SoBigImageRenderer.
Specifies the default background color. The value is specified as three floats (0.0 to 1.0) representing the RGB values of the color. The background color can be set programmatically using the setBackgroundColor method of the classes above.
OIV_BUFFER_OBJECT_CACHE_SIZE
Affects SoCpuBufferObjectCache which manages a cache of SoCpuBufferObject objects. SoBufferObject creates an instance of this class that is primarily used for the LDM tile cache (see SoLDMGlobalResourceParameters for more information). Default size is 50.
OIV_BUFFER_REGION_ENABLE
Affects SoBufferRegion, SoGLRenderAction.
If not specified, the OpenGL extension bufferRegion is enabled and will be used if available on your graphics hardware. Set to zero to disable use of buffer regions.
OIV_CACHE_MODE
If set to 1, Open Inventor 3.0 render caching behavior is used. This may be necessary to produce correct results with some graphics boards.
OIV_CAMERA_TYPE
Affects IvfDocument, IvfRenderArea, SoSceneViewer, SoQtViewer, SoWinViewer, SoXtViewer.
Specifies what kind of camera the viewer should create if none is provided. By default, a Perspective camera is created. To request an Orthographic camera, specify "o", "O", or "0".
OIV_CG_FRAG_PROFILE
Specifies the Cg profile to be used for fragment programs. arbfp1 by default. See SoShaderObject for details.
OIV_CG_VTX_PROFILE
Specifies the Cg profile to be used for vertex programs. arbvp1 by default. See SoShaderObject for details.
OIV_CGM_HARDCOPY_BUFSIZE
Affects SoVectorizeCGMAction.
Specifies the buffer size in bytes for storing CGM calls before writing them to the disk. The default buffer size is 1048576 bytes (1 megabyte). If set to 1, no buffering is done.
OIV_CLIP_TEXT2
When this variable is set, 2D text strings, which are rendered using bitmaps, will be correctly clipped when the string start point is outside the viewport (in previous releases the entire string disappeared).
NOTE: When this variable is set, auto render caching is suppressed by SoText2 in all cases (by default it is not suppressed for single line strings with default LEFT justification). This is really only useful for applications rendering to multiple screens, for example using the MultiPipe extension.
OIV_COLORWHEEL_DBUF [Windows only]
Some displays do not correctly handle the interaction between the hardware cursor and OpenGL drawing in the front buffer. By default the color wheel is single buffered and uses a save/restore scheme when the user drags the "marker". If this produces visual artifacts, try setting this environment variable to force double-buffered rendering.
OIV_COMPAT_24 [Windows only]
If this variable is set to any value, then the Open Inventor 2.4 pixel format selection code is used. Stereo is not possible.
OIV_COMPAT_30
If set to 1, the Open Inventor 3.0 code for handling 2- and 4-component texture images will be used. The 3.0 behavior could reduce performance or produce unexpected results for images that are actually opaque, so it is unlikely you will ever need to set this variable.
OIV_COMPAT_40
If set to 1, the Open Inventor 4.0 code for checking the OpenGL extensions will be used. The 4.0 behavior can detect some extensions even if they are not available on the current graphics hardware.
OIV_COMPAT_CGM_HARDCOPY_400
Affects SoVectorizeCGMAction.
If set to 1, CGM writing onto disk is not buffered (the buffering is only done by stream data writing of the operating system). This value takes precedence over OIV_CGM_HARDCOPY_BUFSIZE.
OIV_COMPAT_HPGL_HARDCOPY_370
Affects SoVectorizeHPGLAction.
If set to 1, reproduces the (incorrect) HardCopy 3.7 line pattern printing behavior. It is unlikely you will ever need to set this variable.
OIV_COMPAT_CONTEXT_80
Affects the state of the compatibility mode for the contexts.
If set to 0 (default) the actual implementation of SoGLContext will be used to manage the OpenGL contexts.
If set to 1 SoGLContext will call the OpenGL makeCurrent function each time the bind() function is called. The unbind() function won't do anything; this mode provides a way to have a valid context outside any traversal. It's useful when third party APIs do direct OpenGL calls.
If set to 2 the getCurrent() function will check the actual OpenGL state instead of using the SoGLContext managment functions. This will prevent issues related to third party code which could call OpenGL makeCurrent() function instead of using SoGLContexts.
OIV_COMPAT_COLOR_RGBA
Starting with Open Inventor 9.0, SbColorRGBA packed color storage is consistent with documentation: previously, alpha value using packed color access method was considered as transparency. Nevertheless, for compatibility reason, user can go back to previous behavior by setting the OIV_COMPAT_COLOR_RGBA to 1.
OIV_COMPLEXITY
Affects SoComplexity.
Specifies the default complexity (0.0 to 1.0). The complexity can be set programmatically using the SoComplexity::value field.
OIV_COMPLEXITY_TYPE
Affects SoComplexity.
Specifies the default complexity type. Valid values are OBJECT_SPACE, SCREEN_SPACE, BOUNDING_BOX. The complexity type can be set programmatically using the SoComplexity::type field.
OIV_CONFIG_FILE
Specifies the full path of the configuration file.
OIV_CREASE_ANGLE_FIX
When set, forces FLAT shaded rendering when creaseAngle = 0. Strictly speaking this is the correct behavior (see SoShapeHints), however it is incompatible with the historical behavior of Open Inventor and may change the appearance of geometry in existing applications. Applied only to SoIndexedTriangleStripSet and SoTriangleStripSet nodes.
OIV_CSG_BUFFER_REGION [Windows only] [SolidViz only]
Allows the SolidViz CSGGroup node rendering algorithm to use the OpenGL Buffer Region extension to speed up save/restore of Z-Buffer task. Classical save and restore of Z-Buffer (glDrawPixels/glReadPixels) is used if this variable is not defined. KTX_BUFFER_REGION: Uses the GL_KTX_buffer_region extension. ARB_BUFFER_REGION: Uses the WGL_ARB_buffer_region extension.
OIV_CURSOR_STYLE [Windows only]
Specifies the cursor style.
- 0 Classic
- 1 XOR
- 2 Shadow
The cursor can also be controlled programmatically. See SoWinViewer.
OIV_DATABASE_CHECK
If set, OpenInventor will perform advanced checks on database objects during intialization and running steps. This variable only applies to debug compilation mode (_DEBUG preprocessor option). NOTE: This variable is all the most useful for users that develop their own Openinventor nodes. User must be aware that even if helpful, this variable leads to a larger memory usage.
OIV_DEBUG_CONFIG
If set, requests that configuration debug output be generated. NOTE: This configuration parameter must be set in the system environment, not in a configuration file.
OIV_DEBUG_PIXEL_FORMAT [Windows only]
If this variable is set to 1, Open Inventor programs will write a file (named pixel.txt) that indicates which pixel format was chosen.
OIV_DEFAULT_ACTION_USE_ALTERNATEREP
If this variable is set to 1, then all action will ask for a potential alternal representation to traversed node. Default is FALSE.
OIV_DECIMATION_GOAL_FPS
Affects SoWinViewer, SoXtViewer, SoQtViewer.
Specifies the default goal number of frames per second. The value can be set programmatically using the setGoalFramesPerSecond method of the classes above.
OIV_DECIMATION_GOAL_NUM_OF_TRIANGLES
Affects SoWinViewer, SoXtViewer, SoQtViewer.
Specifies the default goal number of triangles. The value can be set programmatically using the setGoalNumberOfTriangles method of the classes above.
OIV_DECIMATION_PERCENTAGE
Affects SoWinViewer, SoXtViewer, SoQtViewer.
Specifies the default decimation percentage. The value can be set programmatically using the setFixedPercentage method of the classes above.
OIV_DECIMATION_STRATEGY
Affects SoWinViewer, SoXtViewer, SoQtViewer.
Specifies the default decimation strategy. Valid values are: NORMAL, FIXED_NUM_TRIANGLES, FRAMES_PER_SECOND, FIXED_PERCENTAGE. The value can be set programmatically using the setDecimationStrategy method of the classes above.
OIV_DISABLE_DRAGGER_CTRL_KEY
Affects SoDragPointDragger, SoHandleBoxDragger, SoTrackballDragger, SoTransformerDragger, SoHandleBoxManip, SoTrackballManip, SoTransformerManip.
If set to 1, when the CTRL key is pressed over the dragger, nothing happens. Otherwise, the CTRL key has its usual behavior, which varies from dragger to dragger.
OIV_DISABLED_GL_EXTENSION_LIST
This variable contains a comma separated list of OpenGL extension names to disable explicitly in software. This is useful when encountering a GPU driver bug, or to check performance impact with or wihout a specific extension. See SoGLExtension or www.opengl.org for a list of extension names.
OIV_DRAW_OCTREE
Affects SoOctreeOrdering.
If this environment variable is set and your application uses an SoOctreeOrdering node, an outline of the octree quadrants will be drawn. This is a debugging aid to allow you to see how your scene is distributed throughout the octree.
OIV_ENABLE_PNG_BACKGROUND
Affects SoPNGImageRW (and texture nodes that load PNG files).
Enables the merge of the background into the displayed image. The background replaces transparent parts of the image.
OIV_ENABLE_INMEMORY_TEXT_FILE
Affects SoInput::readTextFile. If TRUE (the default) SoInput::readTextFile will first check if the requested file has been cached in memory using the SoInput::addInMemoryTextFilefilename call. If FALSE, the file will be read from disk and must be accessible.
OIV_PICKING_DEFAULT_MODE
Affects SoRayPickAction for geometric shapes like SoIndexedFaceSet. If "GPU", picking will use GPU picking for shapes implementing this technique. If "CPU", ordinary CPU method is used for all shapes. If not defined, best picking method is automatically chosen, but can be locally modified by using an SoPickStyle node. Please refer to SoRayPickAction documentation for more details. This SoPreference only impacts OIV shapes. For VViz shapes, please refer to IVVR_GPU_PICKING .
OIV_ENVIRONMENT_ATTENUATION
Affects SoEnvironment.
Specifies the default squared, linear, and constant light attenuation coefficients (in that order) with respect to distance of light from surface (for Phong lighting). The values are specified as three floats. The background color can be set programmatically using the SoEnvironment::attenuation field.
OIV_EXTRUSION_EPSILON
Affects SoExtrusion and SoVRMLExtrusion.
If your extrusion appears to twist unexpectedly, try setting this value to a slightly smaller number. The default value is .998.
OIV_FACE_TYPE
Affects SoShapeHints.
Specifies the default face type. Valid values are UNKNOWN, CONVEX. The face type can be set programmatically using the SoShapeHints::faceType field.
OIV_FILE_SEARCH_PATHS
Semi-colon separated path list used to initialize the directory list in SoInput. Most Open Inventor classes that take a file name (for textures, shaders, etc) will search the directories in this list to find the file. Exception: SoDataSet, SoVolumeData and derived classes.
OIV_FOG_COLOR
Affects SoEnvironment.
Specifies the default fog color. The value is specified as three floats (0.0 to 1.0) representing the RGB values of the color. The value can be set programmatically using the SoEnvironment::fogColor field.
OIV_FOG_TYPE
Affects SoEnvironment.
Specifies the default fog type. Valid values are: NONE, HAZE, FOG, SMOKE. The value can be set programmatically using the SoEnvironment::fogType field.
OIV_FOG_VISIBILITY
Affects SoEnvironment.
Specifies the default distance at which fog totally obscures objects. The value can be set programmatically using the SoEnvironment::fogVisibility field.
OIV_FONT_NAME
Affects SoFont.
Specifies the default font name. The value can be set programmatically using the SoFont::name field.
OIV_FONT_PATH
Contains a colon-separated or semicolon-separated list of directories to search for font definition files. NOTE: This item cannot be set via SoPreferences or a configuration file. It must be set in the environment (e.g., using setenv). See SoFont for more information.
OIV_FONT_SIZE
Affects SoFont.
Specifies the default font size. The value can be set programmatically using the SoFont::size field.
OIV_FONT_RENDERSTYLE
Affects SoFont.
Specifies the default font render style. Valid values are POLYGON, TEXTURE, POLYGON_AND_OUTLINE. The value can be set programmatically using the SoFont::renderStyle field.
OIV_FORCE_DUAL_TEX_SHADOW
Setting this variable to 1 tells the FXViz shadow algorithm to not use the OpenGL Shadow extension. This is only useful if your graphics board claims to support the extension but draws the shadows incorrectly or very slowly (e.g., some GeForce2-based boards).
OIV_FORCE_GLU_NURBS
Affects SoNurbsSurface, SoIndexedNurbsSurface.
If set to 1, then NURBS are tessellated and rendered using GLU.
OIV_FORCE_PIXEL_FORMAT [Windows only]
If this environment variable is set to a positive integer, Open Inventor will try to use it as the pixel format. You can list the available pixel formats with the "oglinfo" utility that is provided with the Open Inventor for Windows SDK. To request a pixel format programmatically, use the setPixelFormat method of SoWinGLWidget.
The following special values are provided for your convenience:
- -1 Choose a pixel format without hardware acceleration (if any). This is convenient for helping to determine if a problem is due to hardware acceleration, i.e., if the problem lies in the OpenGL driver or the board hardware.
- -2 Choose the "minimal" pixel format. By default Open Inventor will choose the pixel format with the most capabilities, including stencil buffer, accumulation buffer, etc. On low-end boards it may be possible to get better performance using the pixel format with the least capabilities. Acceleration is still selected.
- -3 Choose the "minimal" pixel format without hardware acceleration.
OIV_FORCE_TEX_COORD_SENDING
Affects shapes derived from SoVertexShape, and only affects user-specified texture coordinates. If set to 1 (TRUE), forces the sending of texture coordinates to the OpenGL pipeline without having a texture bound to the corresponding texture unit. This is useful when working with programmable shaders. Default is 0 (FALSE). The value can be set programmatically using the SoTextureCoordinate2::forceSending field or the SoTextureCoordinate3::forceSending field.
OIV_FORCE_USE_VBO
Affects the SoShapeHints::useVBO default value. Since Open Inventor 8.1 the default value for SoShapeHints::useVBO is TRUE (1), using this variable, you can force back it to FALSE (0). Despite the name, this environment variable just sets the default value for the useVBO field of SoShapeHints nodes created by the application. The default is true. Setting the variable to true or false does not guarantee VBOs will (or will not) be used, because the application might set the useVBO field on some instances of SoShapeHints. Note that vertex arrays will still be used unless specifically prohibited.
OIV_FREETYPE_NAME
Affects SoDynamicLibManager.
Allows you to use your own Freetype dynamic library. Do not add the suffix. Do not add the "lib" prefix on UNIX systems. Do not add the final "D" used in the debug name. Default is "IvDLFreetype".
OIV_FULL_RENDER_WHEN_STILL
Affects SoWinViewer, SoQtViewer, SoXtViewer.
Specifies if the viewer will be default render at full resolution when it sits still for a certain period of time. (0=no, 1=yes). This flag can be set programmatically using the enableFullRenderingWhenStill method of the viewers classes above.
OIV_FULL_SCENE_ANTIALIASING
Affects SoFullSceneAntialiasing.
Specifies whether full scene antialiasing (if already enabled) will be applied to subsequent shapes (0=no, 1=yes). The value can be set programmatically using the SoFullSceneAntialiasing::on field. See SoFullSceneAntialiasing for information on enabling full scene antialiasing.
OIV_FULL_SCENE_ANTIALIASING_FILTER
Affects SoFullSceneAntialiasing.
Specifies which kinds of primitives should be antialiased when full scene antialiasing is enabled. Valid values are ALL or any combination of LINES, POINTS, POLYGONS, and TEXT. The value can be set programmatically using the SoFullSceneAntialiasing::filter field. See SoFullSceneAntialiasing for complete details.
OIV_GL_SMOOTHING
Affects SoGLRenderAction.
Specifies the default smoothing flag (0=no smooth, 1=smooth). The smoothing flag can be set programmatically using SoGLRenderAction::setSmoothing.
OIV_SET_RAY_PRECISION
Affects SoRayPickAction when defining a ray using the setRay method
Specify (in radius) the value of fovy angle defined by the ray. If not set, the default value is set to 0.0003F
OIV_GLSL_DEBUG
Affects SoShaderObject (and derived classes).
Enables display of output generated by the GLSL compiler of the graphics display driver. If not set to TRUE (1), no trace output is generated.
OIV_HC_BLACK_AND_WHITE
Affects subclasses of SoVectorizeAction (HardCopy extension). Force all non-white colors to full black. This is useful because selecting "black & white" in the printer setup dialog normally produces gray scale rendering and some colors may be difficult to see. This option is applied after color translation (e.g. REVERSE_ONLY_BLACK_AND_WHITE).
OIV_HCGDI_APPCONTROL
Affects SoVectorizeGDIAction (HardCopy extension). When this variable is non-zero, the application is responsible for calling StartDoc, StartPage, EndPage and EndDoc to manage the printer. There are two modes, depending on the value of OIV_HCGDI_APPCONTROL:
- 1 : This is the most flexible mode. The application is responsible for setting the map mode, logical to device mapping, etc. (in addition to managing the printer). This mode is normally used in an MFC application.
- 2 : This is the most convenient mode if you only need to manage the printer. SoVectorizeGDIAction will set up the mapping as usual. This mode is only available in Open Inventor 7.2 and higher.
OIV_HCGDI_EDGE_WIDTH
Affects SoVectorizeGDIAction (HardCopy extension). Default is to draw a minimum width line for polygon edges. In most cases this is enough to prevent small triangles from disappearing. If > 0, this value is a scale factor applied to the "nominalWidth" (effectively same as SoDrawStyle::lineWidth). This value is fetched in the constructor so it must be set before creating an SoVectorizeGDIAction.
OIV_HCGDI_POLYGON_COMPAT
Affects SoVectorizeGDIAction (HardCopy extension). Before Open Inventor 8.5.1.2 the action only used a "brush" (no pen) to render GDI polygons. In this case GDI only draws the "interior" of the polygon, so very small polygons could disappear completely because GDI determined that no part of the interior was visible. Although it's unlikely to be needed, this variable allows returning to the pre-8.5.1.2 behavior.
OIVHOME
Specifies the path of the Open Inventor installation directory. Open Inventor may search for the stroke font files as well as pattern files in subdirectories of OIVHOME.
OIVARCH
Specifies the directory that contains all architecture dependent files.
In a standard installation this directory is under the $OIVHOME directory and has subdirectories such as "bin" and "lib". For example: arch-Windows-x86_64-msvc9-Debug contains files for a 64-bit Windows debug build using Visual Studio 2008 (VC++ 9). Open Inventor uses this environment variable for:
- Finding license files (in $OIVHOME/$OIVARCH/License)
- Finding libraries to load dynamicly at runtime (in $OIVHOME/$OIVARCH/bin or lib)
- Finding programs to launch dynamicly (in $OIVHOME/$OIVARCH/bin) (ScaleViz oiru for example)
OIV_INTERACTIVE_DRAW_STYLE
Affects SoWinViewer, SoQtViewer, SoXtViewer.
Specifies the default interactive draw style. Valid values are: VIEW_AS_IS, VIEW_HIDDEN_LINE, VIEW_NO_TEXTURE, VIEW_LOW_COMPLEXITY, VIEW_LINE, VIEW_POINT, VIEW_BBOX, VIEW_LOW_RES_LINE, VIEW_LOW_RES_POINT, VIEW_SAME_AS_STILL. The interactive draw style can be set programmatically using the setDrawStyle method of the viewers classes above.
OIV_INTERSECT_EPSILON
Specifies the epsilon value against which the area of a triangle is checked to eliminate triangles with no area when picking. It allows you to pick objects that have very small coordinate values. Set the value to approximately 10 raised to three times the exponent of the object coordinates. Example: For objects with coordinates of approximately 10E-7, a value of 10E-21 would allow the objects to be picked.
OIV_LD_LIBRARY_PATH
Affects SoDynamicLibManager.
Specifies a single path in which to search for a dynamic library to be loaded. Other paths may be searched as well. See SoDynamicLibManager for details.
OIV_LIBDXF_NAME
Affects SoDynamicLibManager.
Allows you to use your own libDxf dynamic library. Do not add the suffix. Do not add the final "D" used in the debug name. Default is "IvDLDxf".
OIV_LIBFLT_NAME
Affects SoDynamicLibManager.
Allows you to use your own libFlt dynamic library. Do not add the suffix. Do not add the "lib" prefix on UNIX systems. Do not add the final "D" used in the debug name. Default is "IvDLFlt".
OIV_LIBJPEG_NAME
Affects SoDynamicLibManager.
Allows you to use your own libJpeg dynamic library. Do not add the suffix. Do not add the "lib" prefix on UNIX systems. Do not add the final "D" used in the debug name. Default is "IvDLJpeg".
OIV_LIBPROJ4_NAME
Affects SoDynamicLibManager.
Allows you to use your own libProj4 dynamic library. Do not add the suffix. Do not add the "lib" prefix on UNIX systems. Do not add the final "D" used in the debug name. Default is "IvDLProj4".
OIV_LIBTIFF_NAME
Affects SoDynamicLibManager.
Allows you to use your own libTiff dynamic library. Do not add the suffix. Do not add the "lib" prefix on UNIX systems. Do not add the final "D" used in the debug name. Default is "IvDLTiff".
OIV_LICENSE_DEBUG
Specifies the name of the file to which license debug information will be written. If not set, license debug info is not generated.
OIV_LICENSE_FILE
Specifies the full path of the file containing the VSG license strings for Open Inventor and its extensions. Open Inventor searches for a valid password in the following locations: internal unlock string (see SoLockManager), the system registry (Windows only, see Ladmin.htm), OIV_LICENSE_FILE, $OIVHOME/license/password.dat, and password.dat in the current directory.
OIV_LINE_WIDTH
If defined, forces Open Inventor to use line width 1. no matter what line width the program requests. (This was used to improve performance on a system that had notoriously slow wide lines.)
OIV_LOWRESHIGHPERCENT
Affects Remote Rendering.
This variable specifies the rendered image size as a percentage of the actual window size in the normal case. The default is 1.0 (full size).
OIV_LOWRESLOWPERCENT
Affects Remote Rendering.
This variable specifies the rendered image size as a percentage of the actual window size when the Open Inventor viewer is in "Move as
Low-Res" mode. The default is 0.7 (70 percent).
OIV_LOWRESRENDER
Affects Remote Rendering.
If this variable is defined and the target display (local machine) supports OpenGL, then low resolution rendering is enabled. No change to the application is required.
OIV_MATERIALS_PATH [UNIX only]
Affects SoMaterialEditor.
Specifies the path where the material palette will look for materials.
OIV_MAX_ANNO_RENDER2D_SIZE
Affects SoAnnoText3.
Specifies the maximum font size (in pixels) used in font size computed when SoAnnoText3::renderPrintType field is equal to RENDER2D_PRINT_RASTER. The default maximum value is 1000. If you notice a performance issue when rendering and zooming a scene graph containing many SoAnnoText3 nodes, setting this value to a smaller number, such as 64, may improve performance.
OIV_MAX_CACHES
Specifies the maximum number of render caches for all nodes that create render caches, including display lists (e.g. SoSeparator, SoVRMLShape) and texture objects (e.g. SoTexture2, SoVRMLImageTexture). To disable caching entirely, set it to 0. This can reduce memory requirements at the cost of reduced performance.
For multi-pipe rendering based on MPViewer, set it to the number of pipes that will be used.
For multi-GPU rendering using ScaleViz, OIV_MAX_CACHES is the maximum number of render caches per rendering thread (not the total number of render caches). [Replaces IV_SEPARATOR_MAX_CACHES.]
OIV_MAX_FONT_CACHES
Specifies the maximum number of caches that can be used during text computation. Default value is 20; See SoFont for details.
OIV_MAX_SHADOWMAP_SIZE
Specifies the maximum size of the shadowmap used for shadows in SoShadowGroup. This is used to prevent huge textures allocation on some hardware which can take a couple of minutes. Default value is 4096; See So for details.
OIV_MAX_VARIANCE_SHADOWMAP_SIZE
Specifies the maximum size of the variance shadowmap used for shadows in SoShadowGroup. This allows to use a different texture size when variance shadows are used. Default value is 4096; See So for details.
OIV_MAX_TEXTURED_FONT_RES
Specifies the maximum resolution used when generating textured glyph during text computation. (SoFont::renderStyle field must be set to TEXTURE.) The amount of memory used in textured text depends on this value. Default value is 600.
OIV_MIN_TEXTURED_FONT_RES
Specifies the minimum resolution used when generating textured glyph during text computation. (SoFont::renderStyle field must be set to TEXTURE.) The amount of memory used in textured text depends on this value. Default value is 300.
OIV_MIN_VERTEX_VA
Shapes should use Vertex Array (VA) if they contain at least OIV_MIN_VERTEX_VA vertices. Default value is 0. For small shapes (i.e. a small number of vertices) it may be more efficient to use immediate mode (glBegin) instead of doing all the setup to use vertex arrays and VBOs. This environment variable allows you to specify the minimum number of vertices that a shape must have in order to render using vertex arrays. The default is 0, meaning that all shapes are allowed to use vertex arrays. If vertex arrays are prohibited, then VBOs are also prohibited. See SoVertexShape.
NOTE: This variable must be set before Open Inventor is initialized.
OIV_MIN_VERTEX_VBO
Shapes should use Vertex Buffer Object (VBO) if they contain at least OIV_MIN_VERTEX_VBO vertices. Default value is 0. For small shapes (i.e. a small number of vertices) it might be more efficient to use vertex arrays but not VBOs. This environment variable allows you to specify the minimum number of vertices that a shape must have in order to render using VBOs. The default is 0, meaning that all shapes are allowed to use VBOs. You can also disable VBOs for a specific shape, or group of shapes, using the SoShapeHints useVBO field. See SoVertexShape.
NOTE: This variable must be set before Open Inventor is initialized.
OIV_MIN_VERTEX_VAVBO_NOCACHE
Shapes using VBO or VA will deactivate caching if they contain at least OIV_MIN_VERTEX_VAVBO_NOCACHE vertices. Default value is 10000. In general, render caches (display lists) improve rendering performance for small(ish) shapes because the graphics driver will automatically optimize the geometry. And render caches are valuable because they reduce CPU overhead by avoiding traversal of the cached sub-scene graph. However if a large shape can be rendered using vertex arrays or VBOs, then the render performance probably will not be improved by including the shape in a render cache. (The reduced CPU overhead advantage of the render cache might still be useful in some cases. This environment variable basically allows you to specify the threshold number of vertices that defines a "large shape". If a render cache is already open (being built) when the shape is traversed, and the number of vertices is less than this value, then the shape will not use VA/VBO. Conversely, if no render cache is being built when the shape is traversed, and the number of vertices is greater than or equal to this value, then the shape will be rendered using VA/VBO (if possible) and render caching will not be allowed for the current SoSeparator. The default value is 10000 vertices. The application should be aware that Separators containing large shapes may not build a render cache and arrange the scene graph so that other shapes can be render cached. See SoVertexShape.
NOTE: This variable must be set before Open Inventor is initialized.
OIV_MOUSE_WHEEL_ENABLE
Affects SoWin, SoQt.
Allows you to use the mouse wheel to zoom or dolly the camera when using the Open Inventor viewers (examiner, walk, etc.). The mouse wheel has the same kind of camera movement as the right thumbwheel -- dolly or zoom -- depending on the viewer type and camera type. Default is TRUE (1). The value can be set programmatically using the enableMouseWheelDolly method of SoWinViewer or SoQtViewer.
OIV_MP_CONFIG_FILE
Specifies the pathname of the configuration file for the multi-pipe viewer. Default is "./oivmp.cfg".
OIV_MULTITHREAD
Enables/disables multithread (MT) support.
- 0 MT support disabled
- 1 MT support enabled
If OIV_MULTITHREAD is not defined, then MT support is:
- disabled if SoDB::init is called.
- enabled if SoDB::threadInit is called.
OIV_MULTITEXTURING
Enables/disables multitexturing support.
- 0 multitexturing support disabled
- 1 multitexturing support enabled
If OIV_MULTITEXTURING is not defined, multitexturing support is enabled (if your graphics board supports it). Setting this variable to 0 is equivalent to maxTextureUnit equal 1. See SoTextureUnit for details.
OIV_NO_FBO
Set to 1 to disallow use of OpenGL Frame Buffer Object. Default is 0.
OIV_NO_FLEXNET
Set to 1 to disallow FLEXnet licensing checking. Default is 0.
OIV_NURBS_FIX_TRIM_CONNECTIONS
In some cases, trimming curves are not properly connected in a trimming loop. This may result in bad tesselations of NURBS surfaces when using the CONSTANT tessellationType of the NurbsProperty node (the default mode). When this mode is activated, the NURBS tesselation algorithm tries to reconnect trimming curves. Set to 0 to disable this mode. Default is 1.
OIV_NURBS_FORCE_GLU_CONVEXISATION
When set to 1, always use the GLU polygon tesselation instead of the internal one. Before version 7.2, the default behavior was to use the internal tesselation. Sometimes, the result produced by this internal tesselation was wrong when using the CONSTANT tessellationType of the NurbsProperty node (the default mode). Set to 0 to revert to the internal tesselation mode. Default is 1.
OIV_NURBS_CHECK_RATIONAL_TRIM_OUTSIDE_DOMAIN
When set to 0, do not try to limit the values of homogeneous trimming curves coordinates to the boundaries of the NURBS domain. Sometimes, trimming curve points can be defined outside the domain but their tesselated counterparts may lie inside the domain for "heavy" weights. Notice that this test is always performed for non rational coordinates since it is invalid to define trimming curves lying outside the domain. Default is 1: the test is performed.
OIV_NO_IVTUNE
Affects IvTune activation.
If set to 1, disallows interactive activation of an IvTune window from an Open Inventor application. You can also allow/disallow IvTune activation programmatically using the SoDB::setIvTuneAllowed() method. Default is 0.
OIV_IVTUNE_CONFIGURATION_FILE
Specifies the path where IvTune will look for the configuration file to load. Default is "$OIVHOME/data/IvTune/IvtConfiguration.xml"
OIV_IVTUNE_SHORTCUT
Controls the keyboard shortcut used for activating IvTune.
The shortcut is composed of [SHIFT] followed by a second key. Use this environment variable to specify the value of the second key, chosen from the SoKeyboardEvent::Key enum. You can also set IvTune activation shortcut programmatically using the SoIvTune::setShortCutValue() method. Default is 0xFFC9 [F12], which corresponds to a shortcut of [SHIFT] + [F12].
OIV_NO_OVERLAYS
Disables Open Inventor's normal attempt to automatically use overlay planes on all platforms. This can be useful to suppress the warning message on UNIX platforms (when overlays are not available) or to avoid a problem with the overlay planes not being correctly transparent.
OIV_NORMGEN_COMPAT
If set, Open Inventor will use the pre-version 3.1 algorithm for computing normals. This algorithm has very bad performance when the geometry bounding box is asymmetrical. It is not likely you will ever need to set this variable.
OIV_NORMGEN_TOLERANCE
Sets the "tolerance factor" used to test for coincident vertices when computing vertex normal vectors for a geometric primitive. A larger value for OIV_NORMGEN_TOLERANCE results in fewer vertices being considered coincident. This can significantly reduce the time required to compute normal vectors for large geometry, for example MeshViz meshes. The default value is 1000000.
OIV_SEPARATE_SPECULAR_SUPPORT
Enables the use of the GL_EXT_separate_specular extension in OpenInventor. The default value is FALSE
OIV_NO_SHADER_LAYERS_BLEND
Disable the use of fragment shaders when using transparency type SoTransparencyType::SORTED_PIXELS_BLEND.
OIV_NO_TEX_TRIM_NURBS
Affects SoNurbsSurface, SoIndexedNurbsSurface.
Deprecated , use OIV_FORCE_GLU_NURBS instead.
OIV_NO_VBO
Affects SoShapeHints.
VBOs may be used to speed up rendering of SoIndexedFaceSets and SoIndexedTriangleStripSets. If the rendering is not correct, try setting this variable.
OIV_NUM_RENDER_PASSES
Affects SoGLRenderAction.
Specifies the default number of render passes. Must be an integer greater than 1. The number of passes can be set programmatically using SoGLRenderAction::numPasses.
OIV_NUM_SORTED_LAYERS_PASSES
Affects SoGLRenderAction.
Specifies the default number of render passes used when SORTED_PIXELS_BLEND transparency is used. Must be an integer greater than 1. The value can be set programmatically using SoGLRenderAction::setSortedLayersNumPasses.
OIV_OGLLIB_PATH [UNIX only]
Specifies the path to the OpenGL library. It may be useful if this dynamic library cannot be found automatically. Open Inventor needs to open the dynamic OpenGL library to evaluate which interesting extensions is supported.
OIV_OIT_DEFAULT_MODE
Select a specific method used to perform Order Independent Transparency The preference value can be AUTO (default), ABUFFER, KBUFFER, DUALPASS_KBUFFER or DEPTH_PEELING.
- AUTO will try to select the best method based on hardware support and memory needed
- KBUFFER is single pass but has a memory overhead and needs a proprietary extension from Nvidia
- DUALPASS_KBUFFER is dual pass and needs OpenGL 4.2 hardware
- DEPTH_PEELING is the slowest but runs on essentially all hardware
- ABUFFER is fast but has a memory overhead and can exhibit rendering artifacts so it is not recommended
If your hardware doesn't support the selected method, it will fall back to a less advanced one.
OIV_OLD_ERROR_HANDLER
Due to a Windows programming limitation, the error console (SoConsole) is not useable in multi-threaded applications. This environment variable allows you to use the older (Open Inventor 3.1 and earlier) error message handler instead.
OIV_OPENAL_NAME
Affects SoDynamicLibManager.
Allows you to use your own OpenAL dynamic library. Do not add the suffix. Do not add the "lib" prefix on UNIX systems. Do not add the final "D" used in the debug name. Default is "IvDLOpenAL32".
OIV_PBUFFER_DEBUG
Affects SoOffscreenRenderer, SoPBuffer.
Set to 1 to enable debug trace output for Pbuffers.
See also OIV_PBUFFER_ENABLE.
OIV_PBUFFER_ENABLE
Affects SoOffscreenRenderer, SoPBuffer. Set to zero to disallow use of Pbuffers.
The OpenGL Pbuffer extension allows accelerated rendering to off-screen memory. The SoOffscreenRenderer class will automatically use a Pbuffer (if possible) for rendering. In case of problems using Pbuffers, this environment variable may be used.
Note: If Pbuffers are disallowed, OpenGL does rendering in software. This gives low performance and OpenGL extensions will often not be available. In general the image may not match the on-screen image simply because a different renderer is being used. However, the lack of OpenGL extensions can cause the offscreen image to differ signficantly. Following are some of the features that depend on OpenGL extensions: Open Inventor correct transparency, VolumeViz 3D textures, FXViz shadowing and bump mapping.
OIV_PERFCOUNTER_ENABLE
Enable or not the SoPerfCounterManager performance counters manager. By default it is disabled.
OIV_PFD_SUPPORT_COMPOSITION
Specifies if the composition with Aero (Windows Vista and 7) is on or off (0= force off, 1= force on). By default OpenInventor will try to use composition. Note that if you turn it on, PFD_SUPPORT_GDI is unset which will prevent using GDI on the OpenGL render area. Also if you force the composition to off and the device doesn't provide any pixel format with GDI support, OpenInventor will post an error. Note also that it has no effect on SoQt viewers, see http://bugreports.qt.nokia.com/browse/QTBUG-6988.
OIV_PFD_SUPPORT_GDI
Specifies if the GDI support with Aero (Windows Vista and 7) is on or off (0= force off, 1= force on). By default OpenInventor will try to use composition. (See OIV_PFD_SUPPORT_COMPOSITION) GDI support and composition support are exclusive. OIV_PFD_SUPPORT_GDI is preponderant on OIV_PFD_SUPPORT_COMPOSITION, meaning that if both are defined, GDI support is choosen first.
OIV_PICK_GENERATE_ALL_PROPERTIES
Affects SoRayPickAction. Set this variable to true to enable computation of all properties (normal vector, texture coordinates, etc) during pick traversal. Default is FALSE.
OIV_PLUGINS_DIRECTORY
Specifies an additional directory to search for Open Inventor plugins. See SoDB::addPlugin(). Default additional directory is empty.
OIV_POLYGON_OFFSET
Affects SoPolygonOffset.
Specifies if the polygon offset computation is on by default (0=no, 1=yes) The value can be set programmatically using the SoPolygonOffset::on field.
OIV_POLYGON_OFFSET_FACTOR

Starting with Open Inventor 6.0, this environment variable is a synonym for OIV_FONT_PATH. Please see OIV_FONT_PATH for details.
OIV_QT_TIMER_THREAD
Affects SoQt viewers.
If set to 1, specifies that a separate thread should be used to signal the delay sensor timeout.
When mouse events are continuously caught by the event callback , the Qt viewers may 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 does not always occur, and the scene is not updated. If the OIV_QT_TIMER_THREAD is set to 1, a separate thread is used to signal the delay sensor timeout. To avoid possible compatibility problems, the default is to use the existing QTimer mechanism for processing the delay queue timeout.
OIV_REMOTE_ENABLE
Applies to ScaleViz.
- ON - Enable connection of client to get application's viewer frame
- OFF (default) - Disable connection of client to get application's viewer frame
OIV_REMOTE_PORT
Applies to ScaleViz.
Specify the TCP port the application will use to listen for remote client connection. This port must be free (not used by any other daemon or services). Default is 0, meaning the value is dynamically allocated and printed to the console or remote dialog GUI.
OIV_REMOTE_TIMING
Applies to ScaleViz.
A value of 1 enables printing in the console of performance timing feedback about each step of the remote frame compression mechanism for ScaleViz remote rendering. Default is 0.
- ON - Always use remote rendering
- OFF - Never use remote rendering
- AUTO (default) - Use if remote display does not have GLX
See also OIV_REMOTERENDER_BUFFER, OIV_REMOTERENDER_DISPLAY, OIV_LOWRESRENDER, OIV_LOWRESHIGHPERCENT.
- PBUFFER - Use an OpenGL Pbuffer for rendering (Default). Allows accelerated off-screen rendering. If not available, use a Pixmap.
- PIXMAP - Use a Pixmap for rendering. (Was the default value prior to version 3.1)
- SCREEN - Use an on-screen window for rendering. Generally provides best performance, but user must have exclusive use of screen to avoid the window being overlapped by other windows.
OIV_REMOTERENDER_DEBUG
Debug info is enabled when set to "1".
OIV_REMOTERENDER_DISPLAY
Set this to the local X display string. The default is ":0.0". Set to ":0.1" to use the second pipe and so on (if any).
OIV_REMOTERENDER_RGB_BGR
This variable allows to get the right colors with TightVNC.
OIV_REPORT_ZERO_VECTORS
Applies only to the Open Inventor debug libraries.
If set to 0, disables reporting of zero length vectors, specifically direction vectors computed by certain interactive features, e.g., draggers.
OIV_REQUIRE_STENCIL <int>
Provides a strong hint that an OpenGL stencil buffer is required for correct rendering. The integer value is the requested stencil buffer depth (default is 1). On Windows, a pixel format that has a stencil buffer will be chosen even if it is not accelerated.

OIV_SHAPE_TYPE
Affects SoShapeHints.
Specifies the default shape type. Valid values are UNKNOWN, SOLID. The shape type can be set programmatically using the SoShapeHints::shapeType field.
OIV_SHARE_GEOM_MUTEX
By default all the geometry nodes share a single class mutex. This reduces the number of mutexes needed and does not impose any penalty once the geometry is render cached. If geometry cannot be render cached, it may be better to use per-node mutexes by setting this variable to "0" (zero). Notes that in multi-thread mode default value is 0.
OIV_SHARE_LISTS
Specifies what kind of OpenGL display list sharing is allowed.
- 0 Disable display list sharing (same behavior as v2.6 and older)
- 1 Conservative sharing (not available on Unix)
Only add context to a share group containing contexts with the same pixel format. This is the "official" limitation per the Microsoft documentation, but is very limiting.
- 2 Aggressive sharing (default)
Add context to the first share group that OpenGL says we can share with. This may allow us to share between contexts with different pixel formats, which is valuable for single vs. double buffered, stereo vs mono, etc.
OIV_SORTED_LAYERS_TEXTURE_UNIT
If set, the SORTED_PIXELS_BLEND transparency type will use this texture unit internally instead of SoFragmentShader::getMaxTextureImageUnit()-1.
