Open Pascal 54a24e4c5c fix: address review findings from PR #402 MEP systems
- 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
  • 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
