puck_wall_bounce — DRIVE puck op

• Data kinds: signal × signal × scalar × scalar → table

• Call: import fullseye as fs; fs.ledger.puck_wall_bounce(v, normal, e: 'float', kt: 'float' = 1.0) -> 'dict' (to call the implementation directly, import puck; puck.puck_wall_bounce(v, normal, e: 'float', kt: 'float' = 1.0) -> 'dict'; from the registry, opsdrive.get("puck_wall_bounce"))

Usage

> This operator's description has not been translated yet. The original text follows as it is.

壁との衝突: 法線成分 vₙ' = −e vₙ、接線成分 vₜ' = kₜ vₜ(e = 法線の反発係数、kₜ = 接線の保持率 = 接線の反発係数)。

回転は持たない(壁の摩擦で入る回転は接線の減りに畳んである。Cross 2022 のディスク衝突は「滑りか把持か」で接線の

反発係数を書く —— その 2 領域は入れていない)。返り値

`{"v", "vn_in", "vn_out", "vt_in", "vt_out", "energy_ratio"}`。法線だけの衝突なら energy_ratio = e²(門)。

`v·n ≥ 0`(離れていく)なら何もしない。
