Openings now host on the walls a roof segment generates — the base walls under the roof and the coplanar gable/shed/gambrel end faces, so a window can sit in a gable pediment. - core: roof-segment-walls.ts models the four vertical faces as 2D frames (u along face, v height) with convex profile polygons that mirror the wall volume getRoofSegmentBrushes builds; rect-in-profile clamping and anchored resize limits via half-plane algebra. - schemas: optional roofSegmentId on door/window; position is the segment-local wall mid-plane center, rotation[1] the face yaw. - cut: reuses capabilities.roofAccessory.buildCut; new cutScope: 'wall' subtracts from the wall brush only. cascadesViaHostSegment keeps the roof-merge loop from consuming door/window dirty marks (their own systems cascade via parentId). - tools: roof:* handlers in door/window tool + move-tool (the Build-tab preset path), with roofSegmentId cleared/restored across every roof<->wall re-anchor and revert; shared hit resolver normalizes normals through world space (merged mesh vs painted segment frames). - fix: RoofSystem no longer rebuilds per-segment CSG in accessory-reveal mode — the uncut rebuild used to draw over the merged shell's fresh opening until deselect. - fix: the walkthrough collider world now prunes by renderer-effective visibility; stale uncut segment CSG inside the hidden segments-wrapper blocked the player at openings the merged shell had cut through. Known gap: painted segments render per-segment CSG without accessory cuts (pre-existing, also affects skylight/dormer).

@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
