[vtkusers] vtkPointSpriteMapper...

[Eric E. Monson]

Hey Gerrick,

This is a class that was developed by John Biddiscombe at CSCS as part  
of ParaView Meshless. You can see that project and links to download  
the source at:

https://twiki.cscs.ch/twiki/bin/view/ParaViewMeshless

The point sprite mapper can be built and used outside of ParaView in  
regular VTK apps. There are some changes that need to be made to the  
CMake files, though, if you want the Python wrapping to work.

John has used this to deal with huge point data sets, and my  
understanding is that they are working right now to develop this as a  
standard ParaView representation plugin.
