The system supports OpenGL 3D texture mapping.

On some boards, this query may return true even if your board does not support accelerated 3D textures. In this case performance may be slow, and you may prefer to use 2D textures instead. Note: The inability to determine if 3D textures are accelerated is a limitation of OpenGL, not Open Inventor.

The system supports the OpenGL paletted texture extension and/or the texture color table extension.

The system supports the OpenGL texture compression extension.
