[vtkusers] about opengl extensions

[Francois Bertel]

Hi Vicente,

VTK uses OpenGL extensions for some programmable materials (VTK/Rendering/vtkGLSLShader*) and for some volume mappers (VolumeRendering/vtkOpenGLVolumeTextureMapper3D.* and VolumeRendering/vtkOpenGLHAVSVolumeMapper.*).
VTK/Rendering/vtkOpenGLExtensionManager.* is designed to query the available extensions on the current OpenGL context and to load them. I don't think VTK uses vertex buffer objects yet.

Some documents are available here: http://www.vtk.org/Wiki/VTK_Shaders or browse the doxygen doc http://www.vtk.org/doc/nightly/html/
