I am using the latest version of VTK but I think I am having trouble with some of the OpenGL libraries with my graphics card. Does anybody know what version of OpenGL is used with the latest VTK libraries? Thanks,

You need at least OpenGL 3.2 but some features might require more recent version/extensions.
