[vtkusers] speed

[Tim Smith (25121)]

Hi, I'm looking at a project modelling a large dataset in 3d. I looked
at vpython briefly since I'm familiar with python but I found it far too
slow for my purposes - a model composed of just 50,000 spheres ran like
a dog on a mid range quadro card, and my models might go up to a million
data points.
So I've resigned myself to needing to use something like vtk in c++,
however while I wait for it to compile in visual studio, I thought I
might ask if even vtk can handle such a requirement? I need to be able
to rotate and zoom around the models with reasonable ease as well as
turn various components of the model on and off.
