Have you tried vtkLODActor? Also you could just render points rather than
spheres. If you are using vtkGlyph3D with vtkSphereSource as input try
reducing SetThetaResolution and SetPhiResolution. You can also use
vtkMaskPoints to subsample the input data, on large data sets this can be a
good way to still 'get the feel' of the data without displaying everything.
hope this helps,
