Animate semantic state with deterministic Three.js WebGPU/TSL motion. Use for launch or staging kinematics, seekable transform timelines, recurrent fixed-step motion, frame-rate-independent follow, GPU-resident instance motion, moving-frame docking or reparenting, and environment-driven actors.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Procedural Motion Systems Semantic state is the source of truth; transforms are its presentation. Keep one writer for each position, orientation, velocity, phase, and event channel. ## Process ### 1. Declare state and its writer Name the observable motion, SI units, coordinate frame, stable actor identity, initial state, phase/event state, and duration contract: finite with a terminal pose plus velocity/hand-off rule, periodic with a wrap rule, or open-ended with a stop/reset policy. Assign one writer to every animated channel; clips, procedural roots, instance storage, camera rigs, and external solvers may own different channels only through an explicit layering order. When another simulation supplies or reacts to motion, declare: - exchanged quantities, units, frame/origin, state owner, producer, consumers, version, and publication order; - timestamp or half-open interval, cadence, sample phase, interpolation or extrapolation, and discontinuity behavior; - support/filter, validity, staleness, error bound, and missing-value behavior; - rate versus interval-integrated semantics and one-way or two-way reaction ownership and order; …

How to install
mdr add linegel/threejs-complete-set-of-skill/threejs-procedural-motion-systems@sha256:880c6be608b67344The line at the top of this page pins the label git:20260924.4429690, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
