Aymeric RabotandClaude Fable 5 bdfee058bd feat: doors and windows on roof-segment wall faces
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). Twice Codex-reviewed;
details in private-editor plans/editor-roof-wall-openings.md.

@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
