add_ball — DRIVE `ballworld` op

• Data kinds: table × table → scalar

• Call: import fullseye as fs; fs.ledger.add_ball(world: 'dict', mesh: 'dict', p, R=None, *, name: 'str' = 'ball') -> 'int' (to call the implementation directly, import ballworld; ballworld.add_ball(world: 'dict', mesh: 'dict', p, R=None, *, name: 'str' = 'ball') -> 'int'; from the registry, opsdrive.get("add_ball"))

Usage

Adds a ball to the world at pose (p, R). The per-face labels (ball 23 / marker 24) are kept as is. Return value = index into objects.
