Wassim SAMADandClaude Opus 4.7 0a723fa1f2 Wall Phase 3 milestone A: registry skeleton (metadata only)
Lays down the wall folder under @pascal-app/nodes with everything needed
to register the kind, but intentionally without runtime wiring:

- schema.ts re-exports WallNode from core (door/window/item still type
  their parentId against WallNode.shape.id, so the schema stays canonical
  there for now).
- parametrics.ts declares thickness / height / curveOffset for the Phase 4
  inspector. Endpoints and host children are edited via affordances, not
  number inputs, so they're not in parametrics.
- definition.ts encodes capabilities (surfaces, selectable, duplicable,
  deletable — no movable since wall's move is bespoke endpoint-drag),
  relations (hosts doors/windows/items, affectsSpatial slabs/ceilings/
  zones, linkedBy endpoint-match, cascadeDelete descendants), and the
  presentation metadata for the palette. Renderer / system / tool fields
  are deliberately absent — the existing wall-renderer.tsx and
  wall-system.tsx keep serving wall until milestone B.
- feature-flag.ts gates the eventual registration via
  NEXT_PUBLIC_USE_REGISTRY_FOR_WALL (same pattern Phase 2 used for spawn).
- wallDefinition is NOT yet appended to builtinPlugin.nodes — registration
  is what flips the Phase 0 dispatch shims, and we don't want that until
  the runtime port lands. Until then this file is metadata-only.

Two type-side changes pulled forward from Phase 4 to make a metadata-only
definition compile:

- NodeDefinition.renderer becomes optional (the three-checkbox model
  documented in wiki/architecture/node-definitions.md already promises
  this). RegistryRenderer in node-renderer.tsx gains a null-guard so an
  undefined renderer cleanly falls through to the legacy switch.

No runtime behavior change. Walls render and behave exactly as before.

@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
