I've done something that sounds similar - displaying the nearest 2367
galaxies (from the 'Tully Nearby Galaxy Catalog') so you can zoom and
spin. Perfectly smooth on both my desktop machine (fairly high end) and
my laptop, a 1GHz PIII with a GeForce 2, but I haven't checked the
frame rate.

The code and data file a

and

Galaxies are displayed as short cylinders for spirals or spheres for
ellipticals. The orientations are sadly random, not real, in this
version, and the sizes are scaled up by a factor of 10 to make it look
better. Left clicking on a galaxy shows the name in a popup label.
