[vtkusers] use GeForce graphics card in vtk applications

[Jianlong Zhou]

hi, vtk users,

I want to do some program for GeForce 3 graphics card to relize some 
special functions in a vtk  application. Does anyone know which vtk 
class should be derived to relize programming GeForce 3 graphics 
card?

Thanks a lot.
