Of course we can simulate a sphere, but to the point of the well written comment you a responding to, the simulation models in pinball video games don’t even come close the the complexity of the physics of a real world pinball. I played a lot of pinball as a kid, and I’ve played many pinball video games since. I was recently at one of these ‘barcade’ venues and tried my hand at pinball thinking I would be good at it. I couldn’t have been more wrong. I lost all 3 balls immediately just about every game. It’s incredibly difficult and unpredictable. Go to your local barcade and try for yourself :)
