[vtkusers] fastest render method for spheres...?!

[Benjamin Frigan]

David,
yes, I've already tried it a few minutes ago. I think it gets better
when I turn it on, at least with vtkglyph3D but not with the vector of
actors.


Marcus,
but display lists are used by default in VTK, right? So, by turning it
off it gets worse.
