Item is the first kind to use the `def.renderer` escape hatch (custom React component with `useGLTF` + drei + interactive widgets) — not expressible as a pure `def.geometry`. Catalog-backed + multi-host (free / wall / wall-side / ceiling). Files added (packages/nodes/src/item/): - schema.ts: re-exports ItemNode from core. - parametrics.ts: empty groups[]. Item parametrics come from the asset's catalog-defined interactive controls (toggles / sliders / temperature) — too dynamic for the auto-inspector at Stage A. Legacy ItemPanel renders the catalog-driven controls; Phase 5 Stage E will likely use parametrics.customPanel. - definition.ts: capabilities (no `movable` — item move is bespoke MoveItemContent that handles attachTo transitions floor↔wall↔ ceiling mid-drag; capability-driven dispatch keeps legacy mover), parametrics, renderer (wrap-export of ItemRenderer), system bundling ItemSystem + ItemLightSystem, toolHints matching the user's screenshot (Place item / R rotate ccw / T rotate cw / Shift free place / Esc cancel). defaults() casts an object literal with a stub asset since asset is required by the schema; createNode re-parses through ItemNode at runtime. - renderer.tsx: wrap-export of legacy ItemRenderer (~280 lines with useGLTF + interactive widgets — too much to duplicate at Stage A). - system.tsx: bundles ItemSystem + ItemLightSystem. - index.ts: barrel. Files changed: - packages/viewer/src/index.ts: new public exports for ItemRenderer, ItemSystem, ItemLightSystem. - packages/nodes/src/index.ts: appends itemDefinition. - packages/editor/src/components/ui/panels/item-panel.tsx: panel slider-drag fix recipe applied (nodeRef pattern, drop subscribed updateNode dep, drop node from useCallback deps). Item panel has scale + position + rotation sliders all subject to the cascade. Item is the registry's stress test for `def.renderer` escape hatch. GLB loading via useGLTF + drei works as-is; nothing in the registry forces a pure-geometry shape on kinds that don't fit. Phase 5 progress: shelf ✅ spawn ✅ wall ✅ fence ✅ slab ✅ ceiling ✅ door ✅ window ✅ item ✅. Nine kinds on the registry. Stair / roof / zone / containers remain.

return (
<div style={{ width: '100vw', height: '100vh' }}>
<Viewer />
</div>
)
}
Custom Camera Controls
import { Viewer } from '@pascal-app/viewer'
import { CameraControls } from '@react-three/drei'
function App() {
return (
<Viewer selectionManager="custom">
<CameraControls />
</Viewer>
)
}
Viewer State
import { useViewer } from '@pascal-app/viewer'
function ViewerControls() {
const levelMode = useViewer(s => s.levelMode)
const setLevelMode = useViewer(s => s.setLevelMode)
const wallMode = useViewer(s => s.wallMode)
const setWallMode = useViewer(s => s.setWallMode)
return (
<div>
<button onClick={() => setLevelMode('stacked')}>Stacked</button>
<button onClick={() => setLevelMode('exploded')}>Exploded</button>
<button onClick={() => setWallMode('cutaway')}>Cutaway</button>
<button onClick={() => setWallMode('up')}>Full Height</button>
</div>
)
}
Asset CDN Helpers
import { resolveCdnUrl, ASSETS_CDN_URL } from '@pascal-app/viewer'
// Resolves relative paths to CDN URLs
const url = resolveCdnUrl('/items/chair/model.glb')
// → 'https://pascal-cdn.wawasensei.dev/items/chair/model.glb'
// Handles external URLs and asset:// protocol
const externalUrl = resolveCdnUrl('https://example.com/model.glb')
// → 'https://example.com/model.glb' (unchanged)
Features
- WebGPU Rendering - Hardware-accelerated rendering via Three.js WebGPU
