Use for launch kinematics, gravity turns, staging, spin docking, target-frame decomposition, spring-follow motion, rotating-frame alignment, peeling debris, analytic transform timelines, frame-rate-independent response, and quaternion control. --- # Procedural Animation Animate semantic state, not unrelated transform curves. Define phases, coordinate frames, velocities, and ownership before writing per-frame updates. ## Build order 1. Define the timeline phases and event boundaries. 2. Choose the frame for each motion: world, subject local, orbital radial, docking axis, or camera shot. 3. Derive target position/orientation from that frame. 4. Use analytic kinematics for authored travel and springs for responsive convergence. 5. Preserve world transforms when detaching children from a hierarchy. 6. Separate translation, alignment, spin, and secondary debris state. 7. Clamp integration delta and reset every state variable on replay/disposal. Read [references/procedural-motion-and-docking-systems.md](references/procedural-motion-and-docking-systems.md) for the launch, staging, docking, debris, spring, quaternion, and frame-rate-independent response implementations. ## Non-negotiable rules - Use elapsed seconds and `deltaSeconds`; do not make motion frame-count based. - Derive orientation from direction/frame, then apply roll or spin as a separate quaternion. - Decompose docking error into axial and radial components. - Switch from spring convergence to an exact terminal pose at the end of a sequence. - When reparenting an animated object, capture world position, quaternion, and scale before removal. - Use seeded randomness when motion must be reproducible. - Keep visual shake in a bounded envelope and separate it from trajectory. ## Routing boundary Use `$threejs-camera-direction` for shot composition and camera handoffs. Use `$threejs-procedural-vfx` when the deliverable is primarily plasma, sparks, or effect pooling rather than object transform motion.

Install the "threejs-procedural-animation" agent skill from https://github.com/scottstts/Threejs-Awesome-Graphics-Agent-Skills/tree/main/skills/threejs-procedural-animation. Read its SKILL.md or equivalent instructions first, install only the files needed for this workspace, and summarize any required setup before using it. Skill purpose: Build advanced procedural animation in Three.js. Use for launch kinematics, gravity turns, staging, spin docking, target-frame decomposition, spring-follow motion, rotating-frame alignment, peeling debris, analytic transform timelines, frame-rate-independent response, and quaternion control. After the install attempt, report the result to https://www.openagentskill.com/api/agent/outcome with POST JSON {"event_id":"install_<unique-id>","skill_slug":"scottstts-threejs-procedural-animation","task":"Install threejs-procedural-animation","agent":"codex","outcome":"success","install_used":true}. Replace event_id with a unique value and outcome with success or failed. Report success only after the skill is installed and a minimal verification passes. Recorded instruction path: skills/threejs-procedural-animation/SKILL.md. Recorded revision: 04856286f29b9b6e0730e798bd943753492278c3. Confirm the source matches these instructions.
