Licensing (finding 1):
- Mocap library is now 100% CMU-sourced (free for any use). Replaced the 3
Meta/FAIR clips with CMU equivalents: wave=141_16, shuffle=77_29 (creep);
dropped the un-CMU "dab", added twist=141_12. Deleted the 4 committed FAIR
BVHs (dab/jumping/wave_hello/zombie).
- Ship Patrick Hand's SIL OFL license (assets/OFL.txt) beside the bundled font
— OFL permits embedding/redistribution; this is the required attribution.
- Add THIRD_PARTY_NOTICES.md (Patrick Hand OFL + CMU) and rewrite mocap/NOTE.md
to drop the "verify before commercial use" caveat (no longer applicable).
Stale clip names (finding 2):
- Update the /ink-art command files (.claude/.github/.cursor/.codex),
character-design-director, and the creative skills to the current catalog
(wave/twist/…), and point to add-motion.mjs.
- ink-puppet.js: console.warn on an unknown clip name instead of silent dead-time.
Examples (finding 3):
- Remove broken standalone reel.html/momentum.html (they referenced a missing
ink-theater.js and momentum shipped the subset font the fix warns against).
- Keep mocap-figure/ as the canonical self-contained, lintable example; refresh
its bundled clips.js/ink-puppet.js; add examples/README.md with the lint path.
Ships Phases 1-3 so the feature isn't left hanging:
- Phase 1: 12-action mocap library (walk/run/jump/climb/march/kick/sit/wave/dab/
shuffle/dance_spin/dance_glide) from CMU + fair1, with mocap/catalog.json.
Fixes the '4 repeated moves' repetition problem.
- Phase 2: bvh2clip.mjs is skeleton-agnostic (fair1/CMU/Mixamo joint aliases) +
frame cap + --name; add-motion.mjs fetches/converts/rebundles any BVH by CMU
id / URL / path — self-extending, no code changes.
- Phase 3: skill guidance to read catalog.json + choreograph variedly (never
loop a clip), add-motion, and the balloon primitive.
- Engine: InkTheater.balloon() speech-balloon primitive (both audit videos
hand-built it).
- Audit fixes: /animated-drawing skill gains a motion->retarget mapping table
(2 motions crashed on the wrong config) + a 'Compositing into HyperFrames'
section (transparent output, GIF-freezes->VP9-alpha, the linter video
contract) + character-variety guidance (animate the user's/a generated
drawing, not a bundled char) + pipeline-exempt notes.
Example refreshed to the new library + full Patrick Hand TTF.
The agent-seamless character system: motion comes from a LIBRARY of real
motion-capture clips, never hand-tuned per video. Two parts:
- mocap/bvh2clip.mjs: offline BVH(3D) -> compact 2D clip converter (FK +
projection + skeleton-rest scaling), run once per motion; bundled via clips.js.
- ink-puppet.js: runtime that draws a stick figure limb-by-limb (draw-on reveal)
and plays named clips via a declarative choreograph() API. Deterministic /
seek-safe (pose = pure fn of segment local time).
Example (examples/mocap-figure): the pencil figure draws itself, then waves /
dabs / jumps / walks from real mocap. Keeps vector white-ink + draw-on reveal
that Meta AnimatedDrawings (raster, humanoid-only, no reveal) cannot do.
Provenance/licensing: mocap/NOTE.md (prefer free CMU mocap for production).
Reusable engine (ink-theater/ink-theater.js, global InkTheater) for hand-drawn
ink-on-white animated 'moving art', authored for HyperFrames (atelier). Five
seek-safe primitives: variable-width brush strokes (inkPath/inkRibbon),
timeline-driven boil, closed-form damped-spring eases, FABRIK 2D IK + riggable
mascot, and a parametric contraption grammar (crank/gauge/hopper/slot/lever/box).
Adds skills/creative/ink-theater.md (metaphor method + mined archetypes + color
grammar) and README with the HyperFrames font gotcha (webfonts apply to HTML
divs, not SVG <text>). Two reference builds under ink-theater/examples/.
Grounded in deep-research on vector/physics/metaphor foundations (FABRIK,
bounded-biharmonic/ARAP, closed-form springs, LLM metaphor+layout planning).
