kendamaworld op• Data kinds: table → table
• Call: import fullseye as fs; fs.ledger.ken_mesh(kp: 'dict', *, n: 'int' = 32) -> 'dict' (to call the implementation directly, import kendamaworld; kendamaworld.ken_mesh(kp: 'dict', *, n: 'int' = 32) -> 'dict'; from the registry, opsdrive.get("ken_mesh"))
Mesh of the ken + cross-piece (big cup, small cup) + base cup. Origin = center of the cross-piece (hand), ken = +x (ken tip at +x), cross-piece axis = +z (big cup on top).
Face labels: 27 the ken and the body of the sarado (cross piece), 28 big cup (the +z flare and cup of the sarado), 30 small cup (−z), 31 base cup (the open part at the −x end of the ken). Return value {"V", "F", "color" (M,3), "label" (M,), "parts": {"ken": (f0, f1), "cross": (f0, f1)}, "anchors": {...}, "cup_radius", "cup_depth", "ken_length"}. anchors (local coordinates) = cross (0 = centre of the sarado), spike_tip, base_rim (centre of the base cup's rim), big_rim (centre of the big cup's rim), small_rim, tie (string hole of the sarado (0, −cross_radius, 0)), big_axis (+z), small_axis (−z), base_axis (−x), ken_axis (+x), grip (where the trick holds it = kp["grip"]). The 2 closed solids of revolution (ken, sarado) are placed intersecting each other (rendering resolves this by depth). All faces point outward (signed volume > 0).
