Interesting thread metanet.

trying to figure out how to move along a curve at constant velocity sounds like a huge headache to me. if you must, there are papers on this -- specifically, many 3D games use splines to move the camera around during cutscenes, and i'm positive i've read at least one paper on how to get constant-velocity movement over splines in realtime. but it's not likely to be cheap or easy..

This example moves along a path at constant speed using Lagrange interpolation. The calculations are very cheap once the path has been calculated. Try it with 50 balls and it should still run smoothly.
