kendama_world — DRIVE kendamaworld op

• Data kinds: table → table

• Call: import fullseye as fs; fs.ledger.kendama_world(kp: 'dict', *, floor: 'bool' = True, floor_size: 'float' = 4.0, hand=(0.0, 0.0, 1.0), p_ball=None, hang_deg: 'float' = 12.0, hang_dir=(1.0, -1.0, 0.0), subdiv: 'int' = 3, n: 'int' = 32) -> 'dict' (to call the implementation directly, import kendamaworld; kendamaworld.kendama_world(kp: 'dict', *, floor: 'bool' = True, floor_size: 'float' = 4.0, hand=(0.0, 0.0, 1.0), p_ball=None, hang_deg: 'float' = 12.0, hang_dir=(1.0, -1.0, 0.0), subdiv: 'int' = 3, n: 'int' = 32) -> 'dict'; from the registry, opsdrive.get("kendama_world"))

Usage

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

床 + けん(kp の技の姿勢 R_ken、持つ所 kp["grip"] を `hand` に)+ 穴のある玉 + 糸の世界。原点は床、z 上。

玉は皿胴の糸穴からひもの有効長(kp["pendulum_length"])だけ下(真下から `hang_deg だけ hang_dir` 側へ振れた位置 ——

斜め (1, −1) なら方位 0° と 90° の両カメラから横ずれが見える)。`p_ball` を渡せばそこに置く。

床は 0.25 m の升に割る(1 枚の大きな四角形だとカメラの背後にかかる三角形ごと落ちて床が消える)。

返り値の world["kendama"] = `{"ken", "ball", "string"}(objects の索引)+ "kp"`。
