Is there an algorithm for a pool game?
I think most billard/snooker games have a lot of problems with their physic engines. They are far away from realistic and you can't really enjoy the game (especially when snooker is your hobby :) )
So I want to try to make an own physic engine (and own snooker game). I think the physic engine is the most important part of such a game. So my question is:
Do anybody know an open physic enginge I can start with? Is there any literature about such physic problems?
