Three cushion research

These three constants govern how the ball behaves at the cushion:

• μs = 0.212 table friction (point C in diagram); controls how much the table surface grips the ball during the bounce higher values slow the ball's slide across the cloth and transfer more energy into spin.
• μw = 0.165 cushion friction (point I in diagram); determines how strongly the cushion face grips the ball on contact increase it and the ball bites into the cushion, altering the rebound angle and adding side-spin; reduce it and the ball skids off more cleanly.
• ee = 0.98 cushion restitution; sets how elastic the cushion bounce is values close to 1 return nearly all the normal velocity, while lower values produce a softer, more deadened rebound.

Adjust the parameters and share results to discuss. Presets are saved to your browser's local storage (constants are not saved). Use "share all presets" to send your full preset collection to a friend for collaborative research. If you have suggestions for improvement please open an issue on my GitHub repo.
