Pascal 1002a0a980 feat(editor): precise item dimensions — static bounding boxes, placement-math, remove item-mesh-metadata system

- Replace runtime mesh-based bounding-box computation with static dimension-based polygons for item footprints
- Add snapUpToGridStep() and getGridAlignedDimensions() to placement-math for grid-cell-aligned placement wireframes
- Add expandBoundsToGrid() to use-placement-coordinator for consistent wireframe snapping
- Add currentCursorRotationY to PlacementContext; preserve world orientation across item-surface transitions
- Fix item detach from surface: use worldToBuildingLocal() instead of event.localPosition to avoid coordinate-space jump
- Subscribe to useLiveTransforms in FloorplanPanel during placement so R/T keyboard rotation refreshes the 2D overlay immediately
- Fix FloorplanItemImage rotation (+180° to account for top-down camera capture orientation)
- Simplify spatial-grid-manager: single dimension-based getItemLocalBounds(), removes runtime mesh-metadata path
- Remove item-mesh-metadata system (compute-item-mesh-metadata, item-mesh-metadata-system, sync-request)

README.md

@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>
}

Node Types

SiteNode - Root container
BuildingNode - Building within a site
LevelNode - Floor level
WallNode - Vertical wall with optional openings
SlabNode - Floor slab
CeilingNode - Ceiling surface
RoofNode - Roof geometry
ZoneNode - Spatial zone/room
ItemNode - Furniture, fixtures, appliances
ScanNode - 3D scan reference
GuideNode - 2D guide image reference

Systems

Systems process dirty nodes each frame to update geometry:

WallSystem - Wall geometry with mitering and CSG cutouts
SlabSystem - Floor polygon generation
CeilingSystem - Ceiling geometry
RoofSystem - Roof generation
ItemSystem - Item positioning on walls/ceilings/floors
