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

Whether a sphere on a plane is rolling or sliding: slip velocity of the contact point s = v_t − r(ω × n). {"slip_speed", "rolling"} (rolling if |s| < 1e-9).
