I'd seriously recommend you look at VTK again.  I've done exactly what you are
describing with Mayavi:

Disregard the timing info, it's old and with some fixes to MayaVi I wrote
(available in current CVS), and a tweaked glyphs user module (which I can send
you if you want it), the speed is extremely fast even for fairly large
datasets.

Mayavi is finkable, though after using fink to pull it in (so you get vtk and
friends) you might want to update to CVS to get some of the recent fixes which
I think are not yet on the fink version.

Cheers,
