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/core
Core library for Pascal 3D building editor.
Installation
npm install @pascal-app/core
Peer Dependencies
npm install react three @react-three/fiber @react-three/drei
What's Included
- Node Schemas - Zod schemas for all building primitives (walls, slabs, items, etc.)
- Scene State - Zustand store with IndexedDB persistence and undo/redo
- Systems - Geometry generation for walls, floors, ceilings, roofs
- Scene Registry - Fast lookup from node IDs to Three.js objects
- Spatial Grid - Collision detection and placement validation
- Event Bus - Typed event emitter for inter-component communication
- Asset Storage - IndexedDB-based file storage for user-uploaded assets
Usage
import { useScene, WallNode, ItemNode } from '@pascal-app/core'
// Create a wall
const wall = WallNode.parse({
points: [[0, 0], [5, 0]],
height: 3,
thickness: 0.2,
})
useScene.getState().createNode(wall, parentLevelId)
// Subscribe to scene changes
function MyComponent() {
const nodes = useScene((state) => state.nodes)
const walls = Object.values(nodes).filter(n => n.type === 'wall')
return <div>Total walls: {walls.length}</div>
}
