[vtkusers] Question regarding plotting points in 3D

[Wesley Smith]

I've used a derivation of the PolyDataMapper class to support VBO
rendering.  It pretty easy to do.  Just copy and paste into a new
source file, rename the class, and modify the appropriate sections of
code.  I've never rendered 1M points, but if you're going to do that
many, VBOs are your best bet AFAIK.
