Hi Lisa,

I suspect that the performance of trying to visualize
256 million vertices in Blender will be too slow to be

Maybe try vtk or paraview first, then if you're successful
try Blender.

I have been successful visualizing data sets with a large
number of vertices using point sprites, as part of a hack
to vtk.The author of the vtk hack has written a module for
ParaView called pv-meshless to do this:


Hope this helps!
