Dear All,
I want to display a 3D image located in GPU, that I have the pointer, and it will allow rotation etc.
I want to use the VTK in Python and I do not want to do transfers GPU-\>CPU of the image or vice-versa.
Thanks,
Luis Gonçalves

Can it be done with PyCuda with the link below? Or something like it?
