It’s quite satisfying to break and send the balls flying into low orbit, although judging cut angles is distinctly tougher than in normal pool because of the oddities of spherical geometry. I had some difficulties getting Ageia to do gravitation toward a point without screwing up static friction. As a result the balls coast to a stop much too gradually. I haven’t pursued this concept far enough to give it AI for single player.
