Promote the client GLB export into the baked-artifact format from
plans/editor-baked-glb-export.md (phases 0 and 1).
- NodeMaterial -> classic MeshStandardMaterial conversion at export. The
viewer's MeshStandard/LambertNodeMaterial set isNodeMaterial, not
isMeshStandardMaterial, so GLTFExporter would otherwise drop every
surface to a blank default. KTX2 (compressed) maps are decompressed via
WebGPUTextureUtils so the exporter can embed them (PNG for now; KTX2
re-encode is deferred to the phase-3 bake worker).
- Identity stamping from sceneRegistry: node.name = pascalId and
extras = { pascalId, kind, label?, openable?, clips? }; all other
userData stripped so editor/runtime ephemera never reach glTF extras.
- Door/window open clips baked from the build-once + pose-at-t primitives
(door pascalSwingLeaf marker, window poseWindowMovingParts). Clips named
by label ("Door 1: open"), carry extras.loop = false (consumers play
once and hold; dumb glTF players still loop).
- Cutout fix: door/window selection hitboxes hide via material.visible,
which onlyVisible misses, so the hitbox box plugged the wall opening.
Non-renderable container meshes now keep their node but lose geometry;
childless ones are removed.
- Editor-overlay stripping mirrors the thumbnail capture: emit
thumbnail:before/after-capture so scene-layer affordances (handles,
ceiling/site brackets) self-hide, and drop anything off SCENE_LAYER
(gizmos, grid, zone fills).

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
