- core: fix layer violation in level-height.ts — extract sceneRegistry
import, replace with optional WallBaseYResolver callback so core stays
pure (no Three.js mesh state); viewer callers pass resolver, headless
callers (MCP/tests) get deterministic node-data-only result
- core: generalise port-connectivity service from duct-only to all
distribution families — match partners by distributionRole ('run' →
endpoint stretch, 'fitting' → rigid follow) instead of hard-coded
duct-segment/duct-fitting type names; add system-compat guard so
cross-system ports (e.g. supply duct vs waste pipe) don't fuse
- editor: fix port-snap rotation bug in move tool — pass preview node
at live rotation into resolvePortSnap so own-port positions reflect
any mid-drag R/T rotation before computing the snap delta
- editor: wire pipe-trap into UI — add to StructureTool union,
MepToolKind, MEP_ITEMS Build-tab tile, and structure-tools action menu
- test: add port-connectivity-pipe.test.ts — 2 tests covering
pipe-fitting → pipe-segment endpoint drag and cross-system isolation
- test: fix stale pipe-auto-fitting.test.ts wye expectation — author
deliberately chose square sanitary-tee for DWV side-taps (documented
in PR description and PipeFittingNode schema); update the one test
that still expected wye to match the implemented behaviour
- nit: fix optional-chain biome warning in validate-dwv.ts
@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
