kendamaworld op• Data kinds: table → table
• Call: import fullseye as fs; fs.ledger.kendama_pose(world: 'dict', hand, p_ball, *, R_ken=None, R_ball=None) -> 'dict' (to call the implementation directly, import kendamaworld; kendamaworld.kendama_pose(world: 'dict', hand, p_ball, *, R_ken=None, R_ball=None) -> 'dict'; from the registry, opsdrive.get("kendama_pose"))
Sets the state of the kendama world: the ken (1 rigid body; grip point kp["grip"] at hand hand, pose R_ken defaulting to the trick pose kp["R_ken"] in kp: cross-piece center = hand − R·grip), the ball (center p_ball), and the string (cross-piece string hole → ball string hole). R_ball defaults to the rotation that points the ball's string hole (−HOLE_AXIS_LOCAL) at the cross-piece's string hole (the ball's rotation is not solved: correct while taut, approximate in flight). Returns {"tie", "cup" (rim center of the receiving cup), "cup_axis", "cross" (cross-piece center), "string_hole", "hole_axis" (direction of the large hole, world), "R_ball"}. world is the one from kendama_world (world["kendama"] is required).
