As you can see, I'm trying to get a good physics model going, this was one
of my first attempts.

Interesting, how did you manage to get the thing rolling once
it stops bouncing?

does it work if you put objects in the scene as well?

no, this scene was hard coded, ie, the direction of the acceleration, the
normal of the bounce, the only thing the ball "sees" is the floor. It was
just a test of vector acceleration and velocity.

Well, the rotation is faked, the equation I used makes it look natural only
when its on the floor, it goes way to fast when its bouncing. Basically
every time it touches the floor I made it lose velocity. It retains almost
the same (x,y) speed when its bouncing and slows down quickly after it
settles on the floor.

I think it should reverse the direction of rotation when it bounces.
Superballs do, pool balls as well, so...
