Aymeric RabotandClaude Opus 4.8 c9121d322c Merge origin/main (#407 placement restructure) into opening-proximity-guides
#407 ("Always-visible placement ghosts + true-nearest 2D opening snap")
restructured the door/window placement tools: it split the old
create-in-resolve into a pure resolveWallPlacement() + side-effecting
applyWallTarget(), added an off-host floating ghost (fallbackPose / showGhostAt),
unified wall hover into onWallHover, and extracted commit{Door,Window}AtWall.

Conflict resolution (door/tool.tsx, window/tool.tsx):
- Re-homed the single publishOpeningGuidesForWallEvent() call into applyWallTarget
  (after the draft update + updateCursor), using that scope (wall,
  getSlabElevationForWall(wall)); door includeVertical:false, window true.
- Routed clearOpeningGuides3D() through showGhostAt so every off-host fallback
  path clears; kept clears in hideCursor, commit helpers, onRoofHover, teardown.
- Made the window sill snap (resolvePlacementY) event-free and call it from the
  pure resolveWallPlacement, so hover + click both get sill/centre/top snapping;
  Shift bypasses, the moving draft is excluded via ignoreId.
- Dropped the branch's inline onWallClick in favour of #407's onWallClick +
  commitWindowAtWall (no behavior lost).
- Reconstructed both files' import blocks, which the auto-merge had truncated to
  stubs (only tsc caught it).

All other conflicts auto-merged (registry types, floorplan-registry-layer,
both move-tools). Verified: typecheck 9/9, biome clean, nodes 169 + core 594
tests pass, editor `bun run build` 7/7. Merge resolution reviewed by Codex
(adversarial): no semantic regressions; all #407 behavior preserved.

@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
