Same shape as fence — thin renderer + system re-export, capabilities declared, panel slider-drag fix recipe applied. Pure geometry + floor-plan ports are later milestones. Files added (packages/nodes/src/slab/): - schema.ts: re-exports SlabNode from core. - parametrics.ts: elevation slider only. Polygon + holes edited via floor-plan boundary / hole editors, not number inputs. - definition.ts: capabilities (no `movable` — slab move is bespoke whole-translation through MoveSlabTool that integrates with the boundary editor; capability-driven dispatch keeps the legacy mover), surfaces.top with elevation-as-height for stacked items, relations (hosts: ['item'], cascadeDelete: 'descendants'), toolHints (trace / finish / cancel for the placement tool). - renderer.tsx: thin placeholder mesh + markDirty on mount + node events + cached material via the same getSlabMaterial pattern as the legacy renderer (preset apply on shared material instance). - system.tsx: re-exports the legacy SlabSystem from viewer. - index.ts: barrel. Files changed: - packages/viewer/src/index.ts: exports SlabSystem (already had DEFAULT_SLAB_MATERIAL, applyMaterialPresetToMaterials, createMaterial from earlier exports). - packages/nodes/src/index.ts: appends slabDefinition unconditionally to builtinPlugin.nodes. - packages/editor/src/components/ui/panels/slab-panel.tsx: applied the panel slider-drag fix recipe from plans/editor-node-registry.md prophylactically (nodeRef pattern, useScene.getState().updateNode inside handler, drop subscribed updateNode dep). Slab's elevation slider is the only drag-driven control in the panel — would have triggered the same Maximum update depth cascade as wall/fence. No behavior change. Slab now mounts via the registry path, but the legacy SlabSystem still does the actual polygon triangulation + hole CSG work (re-exported, not duplicated).

npm install react three @react-three/fiber @react-three/drei
What's Included
- Viewer Component - WebGPU-powered 3D viewer with camera controls
- Node Renderers - React Three Fiber components for all node types
- Post-Processing - SSGI (ambient occlusion + global illumination), TRAA (anti-aliasing), outline effects
- Level System - Level visibility and positioning (stacked/exploded/solo modes)

- Asset URL Helpers - CDN URL resolution for models and textures
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
- Post-Processing - SSGI for realistic lighting, outline effects for selection
- Level Modes - Stacked, exploded, or solo level display
- Wall Cutaway - Automatic wall hiding for interior views
- Camera Modes - Perspective and orthographic projection
- Scan/Guide Support - 3D scans and 2D guide images
