This is pretty cool! Thanks for sharing. What I've found when doing the "remove velocity" thing in the past (sweeping spheres against trimeshes, mostly), is that the amount of bounce you get (if you have >0 restitution) varies randomly. The reason being that "almost all" versus "almost none" of the velocity will be removed for any given timestep, depending on how soon within the timestep the object will intersect the target. It's possible to hack with things like "assumed velocity" being remembered at the beginning of the time step -- do you have any thoughts on possibly better solutions? (There's also the discontinuity in motion from removing a random amount of time, but as you say -- you gotta stop somewhere ;-) Sincerely, jw -- Americans might object: there is no way we would sacrifice our living standards for the benefit of people in the rest of the world. Nevertheless, whether we get there willingly or not, we shall soon have lower consumption rates, because our present rates are unsustainable.
