roll_slide_state — DRIVE ball op

• Data kinds: table → table

• Call: import fullseye as fs; fs.ledger.roll_slide_state(v_t, omega, normal, bp: 'dict') -> 'dict' (to call the implementation directly, import ballistics; ballistics.roll_slide_state(v_t, omega, normal, bp: 'dict') -> 'dict'; from the registry, opsdrive.get("roll_slide_state"))

Usage

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

平面上の球が転がっているか滑っているか: 接触点の滑り速度 s = v_t − r(ω × n)。`{"slip_speed", "rolling"}`

(|s| < 1e-9 なら転がり)。
