- room3d.js: pure-module port of rigroom retarget, target parameterized; _selftest bakes across two mismatched-rest skeletons (maxErr 6.4e-12) - stage.js: Stage class (IBL, gizmo, entities, clip bake cache) per PLAN §4.2 - dock.js: asset dock + inspector, offline file-drop + clip retarget - index.html/style.css: grid layout, guarded timeline import (page survives B absent) Verified in-browser end-to-end: Mixamo char loaded+normalized, backdrop plane, gizmo move, running clip retargeted (66 tracks) and animating live.

## 2026-07-18 session 1
|
|
DONE: M1 shipped and verified end-to-end in a browser.
|
|
- `web/room3d.js` — ported the rigroom retarget as a pure ES module (no DOM/globals).
|
|
Exports parseAny/canon/boneMap/captureRest/bakeRetarget/disposeRoot/stats + `_selftest`.
|
|
bakeRetarget is now `(clip, srcRoot, srcRest, tgtRoot, tgtRest, opts?)` — target is a
|
|
parameter instead of the closed-over `char`. Algorithm kept byte-for-byte (30fps world-delta
|
|
bake, hips-height ratio, quat sign continuity, dup-hierarchy dedupe). Added `.bvh` to parseAny.
|
|
- `web/stage.js` — `class Stage` per PLAN §4.2. IBL (RoomEnvironment+PMREM), grid+circle floor,
|
|
OrbitControls director cam, TransformControls gizmo (W/E/R), raycast select, shadow-casting.
|
|
addEntity handles character/prop/backdrop(plane|corner|dome)/camera/light; wrapper-Group holds
|
|
all transforms, loaded root normalized+grounded underneath. prepareClip caches parse-per-path and
|
|
bake-per-(entity,path,index). captureState/applyState round-trip entities.
|
|
- `web/dock.js` — asset dock (Characters/Props/Backdrops/Animations tabs from `/assets/tree`,
|
|
offline→file-drop) + inspector (transform/params editors, ⏺key dispatches `scenegod:capturekey`,
|
|
delete). Local drop: image→backdrop, mesh→character, clip-onto-selected-character→bake+play.
|
|
- `web/index.html` + `web/style.css` — CSS-grid layout (dock/view/inspector/timeline), rigroom
|
|
importmap (three 0.160.0), `?selftest=1` badge. Timeline loaded via guarded dynamic import so the
|
|
page never breaks when Lane B's file is absent.
|
|
|
|
VERIFICATION (browser, in-app):
|
|
- `?selftest=1`: PASS — two 3-bone skeletons, different rests+namespaces, baked 1s clip,
|
|
world-delta match maxErr=6.4e-12, srcMoved=0.224rad (guard against a silently-frozen source).
|
|
- Real end-to-end (Female_mixamo.fbx char + "Running.fbx" clip + a jpg backdrop, served from a
|
|
throwaway scratchpad harness): char loaded (65 bones, 18.6k tris, normalized), gizmo-moved,
|
|
clip retargeted (66 tracks) and animating live. Screenshot: `logs/shots/m1-lady-running.png`.
|
|
- Page boots with zero console errors with BOTH timeline.js and the server absent.
|
|
|
|
DECISIONS:
|
|
- selftest uses underscore namespaces (`mixamorig1_`/`mixamorig4_`), not colon — a colon in a bone
|
|
name breaks three's PropertyBinding so the source clip wouldn't bind (silent pass). canon() still
|
|
collapses both to the same key, which is the thing under test.
|
|
- Added `Stage.prepareClipUpload(id, buf, name, idx)` (bake from in-memory bytes) so the offline
|
|
file-drop path can retarget without a server. `Stage.setMixerAuto(false)` lets Lane B take over
|
|
mixer stepping at SYNC 1 (default true so dropped clips preview standalone now).
|
|
- backdrop param edits (mode/image/width) don't rebuild the mesh yet — marked M2. fov/light
|
|
color/intensity are live.
|
|
|
|
BLOCKED/REQUESTS:
|
|
- @Lane C: please confirm the item shape inside `/assets/tree` arrays. dock.js tolerates both a
|
|
bare path string and `{path,name,files:[{path,ext}]}` (rigroom-style) for now — tell me the real
|
|
one and I'll drop the fallback. Also confirm the page is served such that absolute `/web/*.js`
|
|
imports resolve (I used `/web/...` to be URL-independent).
|
|
|
|
NEXT (M2, do not start until orchestrator flips the milestone line):
|
|
- multiple cameras + PiP overlay via renderActiveCamera, light entity param plumbing polish,
|
|
backdrop rebuild-on-param-change, drag-from-dock onto viewport (currently click-to-add).
