Proves the unified (nodeId, slotId) slot contract on a procedural generator, beyond items and walls. A shelf now exposes three paintable slots — shelves / frame / back — painted through the same PaintCapability dispatch and the same node.slots: Record<slotId, MaterialRef> shape items use. Foundation (shared, reusable by future procedural kinds): - core: SlotDeclaration type + capabilities.slots(node) registry declaration; GeometryContext gains `materials` so a pure builder can resolve scene:<id> slot refs without importing useScene. - viewer GeometrySystem: threads the scene material library into every builder ctx, and re-dirties (bypassing the geometryKey skip) any geometry node that references a scene material when that material changes — so editing a custom colour propagates to every shelf using it, matching items. Shelf: - schema: slots: Record<string, MaterialRef> (mirrors ItemNode). - geometry: per-slot material resolution (slot override -> legacy whole-shelf -> declared default colour); every mesh stamped with userData.slotId; DEFAULT_SHELF_MATERIAL retired (declared default gives identical off-white). - paint.ts: PaintCapability (resolveRole from userData.slotId, scene-material commit for one-off colours, preview restricted to __fromGeometry meshes so hosted items aren't ghosted, getEffectiveMaterial incl. legacy fallback). - definition: paint + slots capabilities; slots folded into geometryKey.

Usage
import { Viewer, useViewer } from '@pascal-app/viewer'
import { useScene } from '@pascal-app/core'
function App() {
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
