[vtkusers] How do we check weather my VTK application is using GPU/ Graphic card

[Dan Lipsa]

You'll have to cast your render window to vtkOpenGLRenderWindow.
If w is your render window you have to:

vtkOpenGLExtensionManager *extensions = w->GetExtensionManager();
std::cout << extensions->GetDriverGLVendor() << std::endl
              << extensions->GetDriverGLVersion() << std::endl
              << extensions->GetDriverGLRenderer() << std::endl;
