To be clear I was sad about the lack of comments in the original code. It shouldn't be that hard to find where the collision detection occurs.
It's nice to be able to point to this line: https://github.com/k4zmu2a/SpaceCadetPinball/blob/5947727f80...
And, while it is true that the code is sparsely commented, the geometry code that computes ray intersections is commented.
I'm curious, didn't they just call you or Danny (I believe that's Danny Thorpe, who is currently working for Microsoft) for assistance?
