[vtkusers] vtk arrays and opengl buffers

[Micha Feigin]

Does VTK use OpenGL buffer objects (pbo, vbo etc) for things such as vtkFloatArray and vtkPoints, and if so is it possible to access/modify them directly?

I want to use the GPU to modify the array data instead of the CPU (shaders/cuda). Is that possible without copying data back and fourth?

Thanks
