#407 ("Always-visible placement ghosts + true-nearest 2D opening snap") restructured the door/window placement tools: it split the old create-in-resolve into a pure resolveWallPlacement() + side-effecting applyWallTarget(), added an off-host floating ghost (fallbackPose / showGhostAt), unified wall hover into onWallHover, and extracted commit{Door,Window}AtWall. Conflict resolution (door/tool.tsx, window/tool.tsx): - Re-homed the single publishOpeningGuidesForWallEvent() call into applyWallTarget (after the draft update + updateCursor), using that scope (wall, getSlabElevationForWall(wall)); door includeVertical:false, window true. - Routed clearOpeningGuides3D() through showGhostAt so every off-host fallback path clears; kept clears in hideCursor, commit helpers, onRoofHover, teardown. - Made the window sill snap (resolvePlacementY) event-free and call it from the pure resolveWallPlacement, so hover + click both get sill/centre/top snapping; Shift bypasses, the moving draft is excluded via ignoreId. - Dropped the branch's inline onWallClick in favour of #407's onWallClick + commitWindowAtWall (no behavior lost). - Reconstructed both files' import blocks, which the auto-merge had truncated to stubs (only tsc caught it). All other conflicts auto-merged (registry types, floorplan-registry-layer, both move-tools). Verified: typecheck 9/9, biome clean, nodes 169 + core 594 tests pass, editor `bun run build` 7/7. Merge resolution reviewed by Codex (adversarial): no semantic regressions; all #407 behavior preserved. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

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
