PascalandGitHub 00b8f42899 feat: move/rotate building + relative positioning for all tools (#220)
Sync monorepo PRs #243 and #248 to the open-source editor.

Move/Rotate Building:
- New move-building-tool with grid snapping, R/T rotation, and Esc cancel
- Floating building action menu with move button
- Building helper with keyboard shortcut hints
- BuildingRenderer now applies position and rotation from node data

Building-Relative Coordinate System:
- GridEvent gains localPosition (building-local coords)
- use-grid-events computes building-local intersection from building mesh
- ToolManager wraps building-relative tools in a building-local <group>
- All tools (wall, slab, ceiling, stair, roof, zone, polygon-editor,
  placement coordinator) updated to use event.localPosition
- Placement coordinator adds worldToBuildingLocal helper for cursor
  position conversion

2D Floorplan Fix:
- SVG layers wrapped in <g transform=rotate(...)> for building rotation
- Pointer-to-plan conversion un-rotates when building is rotated
- Grid events from 2D include localPosition

Store Changes:
- useEditor movingNode union includes BuildingNode
- NodeActionMenu onDelete is now optional (buildings can move but not delete)

@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
