My program cannot do that, but it can show gravitational field as equipotentials (iso-contours), would that be useful to you?

Side view of a galaxy made of 1M particles (rendered in SpaceSim)

Turns out that adding a dust band to the equatorial plane adds quite a bit of realism to the rendering of galaxies.
