VTK uses OpenGL underneath so whatever acceleration you get with
OpenGL, you should get with VTK except that VTK will add some
overhead.  Basically, the answer to your question is yes, VTK also
supports hardware acceleration if you compiled VTK with OpenGL/Mesa
and your OpenGL/Mesa itself is accelerated.  I am not sure about the
{Carbon,Cocoa,WinCE}RenderWindows.
