Just to be sure, which volume mapper are you using?  CPU ray casting can be quite slow.

Hi all,

                Got a question and not sure what's going on.  I have an ATI Radeon HD 7700 graphics card.  I can successfully create a small vtkvolume, but, when I try to rotate the volume, it's incredibly slow.  I saw some postings several years ago about vtk volume issues with the ATI cards.

                Any idea's what's going on?

Doug
