3D bouncing ball update

I decided to go and try out the bouncing ball again, finally after a few goes I believe that I got it working pretty well. The ball still seems to be twisting slightly through the bounce so that can be improved. I do feel like the overall movement is a lot more smoother than my other few attempts.
