0.12.3

Characters out to other engines and any mesh rigged well: a GLB read with no engine, any rigged body written as a skinned GLB that plays UAL's clips by name in three.js, Unity, Godot and Blender, and its springs as VRMC_springBone; the rig tool's fixes for AI-made meshes; draped cloth in the tailor; and scenes as agent tools and for a screen reader.

Size: barrel (min, packages external) 1596.0 KB raw / 555.0 KB gz, up 85.6 KB / 31.3 KB gz (+5.7%): scenes as agent tools, widget semantics, the screen-reader mirror and the scene description, and the drape and remesh are in the barrel; glb-rig, rigged-body-glb, ual-rest and spring-vrm are subpaths.

Added

• tosijs-3d/glb-rig: glbRigTriangles(bytes, { pick }) reads a mesh file's triangles for rigging with no engine: the file's frame, a skinned mesh at rest, one surface per material carrying its glTF material and its pictures as bytes, eyes split out. It agrees with loadRigTriangles, and bodyFromMarkers on it rigs a body with no scene (the same bytes and markers give the same weights).
• tosijs-3d/rigged-body-glb: riggedBodyGlb(body, { naming, restPose, height, recipe, extras }) writes any rigged body (from the rig tool, a file's own skin, MakeHuman) as a skinned GLB in Dramatis's export profile: UAL's 65 joints with UAL's rest frames, so UAL's clips play on it by name; a T-pose by default (or the body as rigged); the soles at y = 0 under the origin; body and eyes meshes; the file's own materials and pictures; UE or Mixamo joint names. tosijs-3d/ual-rest is UAL's rest pose as data (bin/ual-rest.ts regenerates it).
• tosijs-3d/spring-vrm: a rig recipe's springs (a tail, strands hung from a bone, with colliders) go out as VRMC_springBone, which three-vrm, UniVRM and Godot's VRM importer read with no setup, and as TOSIJS_spring_chains with our own settings (springChainsSchema()). The page says where VRM's spring model differs from ours.
• writeSkinnedGlb writes emissive materials and root-level extensions.
• Draped cloth in the tailor (tosijs-3d/cloth-drape, drapeGarment): an outline becomes a front and a back piece laid over the body, sewn up its steep sides, bridged over hollows and settled under gravity. Pick it as "made by: drape". The tailor cuts from an even surface laid over the body at a density you pick, finer where the body is thin.
• Character builder: Tonio's AI-made characters (Keisha and Kevin, in underwear and in spacesuits) are bodies, one picked at random on a first visit; a View menu on the system bar, shared with the hosted rig tool, with a right-hand view that follows the palm through the clip; clips from a file (any skinned GLB's animations, Mixamo's or Meshy's, retargeted onto the body shown); every clip in the library; hold an item in the right hand, placed by its grip and saved with the character (handSocket, deriveGrip, heldGrip); body detail draws MakeHuman's own lighter body proxies; revert, delete, and the selector shows the character on screen.
• Rig tool: markers colour-coded with a reference mannequin; a dragged wrist or knee carries its hand or foot, a dragged shoulder or elbow the markers below it; joints mode shows every joint.
• Scenes as agent tools (b3d-agent): each <tosi-b3d> offers tools on WebMCP (registerTool only) and on window.b3dAgent: b3d_<scene>_scene and _places (named things and beacons, in world metres, with distance and bearing), _snapshot, _control_go (drives the vehicle in focus to a named place with its own controls; the player's input cancels it), _control_hold, _control_status, _control_stop, and the settings panel (_panel, _panel_set, _panel_activate). Closed by default: enableSceneAgents({ expose: 'all' | 'read' }) opens the page, and a scene's new agent attribute (read, on, off) overrides it. b3d.originOffset is how far the floating origin has moved. Changing a scene's agent (or its name) after it is on the page updates its tools (#3699).
• bun run xr --flat --script now runs the script (it was ignored without VR), and a script that throws fails the run.
• semantics() on every panel widget (tosijs-3d/widget-semantics): a control says what it is (role, name, value) and can be set or pressed through its own path, as a hand would. panel.controls() reads a panel as a tree of named controls, including an open popup's form; findControl and nameProblems (unnamed or duplicate controls) work on it. inputField and vector3d take a name; tabs3d a name. This is the base the WebMCP tools and the screen-reader mirror are built on (#3699).
• A screen reader can use the settings panel (tosijs-3d/aria-mirror): an open flat panel is mirrored as visually hidden HTML controls (buttons, switches, range inputs, selects, text and number fields; sections as headings), which set or press the panel's own widgets. The system bar's HTML buttons now stay in the accessibility tree in scene mode (they were visibility: hidden) and appear while one has keyboard focus, so Tab goes from the owl into the settings. ariaMirror(host, read) mirrors any panel (#3699).
• Every demo's settings panel passes the name test (63 pages, about 1000 controls). The big editors describe themselves too: curve3d and footprint3d are editors whose value is their points and whose options are their presets (set either), and curveProgram3d, lightEditor3d and terrainEditor3d list their rows. A list3d item may carry a title, its accessible name when the label is not unique; an indented label is trimmed (#3699).
• A keyboard and screen-reader pass over the panels (bun run screen-reader <page> --steps …, a driver that reads only Chrome's accessibility tree and presses real keys). Fixes from it: the owl says whether its panel is open (aria-expanded); a slider announces its formatted value (semantics().valueText, aria-valuetext: "50 km", "±13 °C"); a log-scale slider is stepped along its track, not in equal steps of its value; focus stays in place when the control it was on is renamed (Pause becoming Resume); a toolbar with no name is "tools". button3d takes a title (its name and tooltip when the label is a glyph), and the name test now reports a control named only by a glyph such as ⋯ (#3699).
• The 3D view for a screen reader: the canvas is an image named "
