Heres a quick list of the current bugs i have discovered durring testing and yet remain unresolved. -There is an unknown assertion being thrown because we are trying to normalize the zero vector. This seems to happen after a series of very quick collisions mostly when balls that are going slow collide. -If you shoot a ball at the walls on the shorter end of the table it gets stuck there and stops. This happens for both the que ball and other balls. The short walls must be the first wall the ball hits it seems. -When two balls collide v1 +v2 != v1' +v2' all of the time. This could be because of numerical inaccuracies or could be because of a mistake in our physics. One possible cause of this problem could be that we are not comparing realtive velocities. -- AdamCarasso - 02 May 2004
