Visual Gesture Editor
Full authoring loop for hand gestures, no headset required.
- HandGestureEditorView: complete editor UI. Drag joints on a 2D hand, live rotating 3D skeleton preview overlaid via RealityView, presets (open, fist, point, peace, thumbs up, pinch), left/right picker, match-either-hand toggle, per-finger fine tune sliders, threshold slider, save callback and ShareLink JSON export.
- HandPoseTemplate: procedural hand model (curl + splay per finger). Drags solve inverse kinematics so fingers bend anatomically with bone lengths preserved. Seed the editor from any captured or imported gesture via fitted(to:).
- HandPoseEditor2DView and HandSkeleton3DView available standalone. visionOS, iOS 18, macOS 15.
- Matching upgrades: canonical frame alignment (wrist roll and axis conventions no longer break matches) and mirrored matching (.either gestures authored on one hand fire on the other).
- 10 new unit tests, 18/18 passing. Builds clean for macOS and visionOS.
