[vtkusers] OpenGL with VTK

[rakesh patil]

Thanks Rocco,

I have taken the same approach. But was little bit confused. The procedure
(Pipeline) will remain same right? So I'll pass the polydata object to
derived mapper and then write the rendering code, and set this mapper to a
normal actor. Am I correct? Do I have to use normal actor or an OpenGL
actor..??

Thanks

Regards
