- core: decouple drag-follow from distributionRole — add portConnectivityFollow flag to NodeDefinition; pipe-trap opts out (portConnectivityFollow: false) so dragging a connected pipe endpoint stretches the trap arm instead of yanking the anchored trap fixture - core: remove the module-level getLevelHeight cache entirely — it was keyed only by nodes-object identity, which could return stale heights for in-place mutations by pure/headless callers. The function is now fully pure and deterministic; viewer hot path recomputes per frame as before (the cache only ever skipped the resolver-free branch) - test: harden port-connectivity-pipe.test.ts — real DuctSegmentNode cross-family isolation case (was waste-vs-vent), new pipe-trap anchor case (run drag doesn't move trap; trap drag still stretches run), and beforeEach/afterEach registry reset instead of leaky beforeAll - nit: biome format/import-order on all touched files
@pascal-app/viewer
3D viewer component for Pascal building editor.
Installation
npm install @pascal-app/viewer @pascal-app/core
Peer Dependencies
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)
- Wall Cutout System - Dynamic wall hiding based on camera position
- 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
