Pure, Three.js-free wall-local geometry that will power directly-visible
proximity guides for doors and windows (rendered in the follow-up phases):
- sill / head height (floor → bottom edge, top edge → wall top)
- edge-to-edge proximity clearance to the nearest neighbour on each side
(or the wall end), with overlap suppression
- along-wall alignment (edge/centre coincidence with a neighbour)
- vertical alignment (shared sill / centre / top — "same sill height")
- Figma-style equal-spacing run detection across a series of 3+ openings
Single `computeOpeningGuides` entry plus exported detectors; 23 unit tests.
Codex-reviewed — equal-spacing uses a longest-equal-window scan (a greedy
first-gap anchor dropped valid runs), edge gaps suppress straddling overlaps,
and the alignment detectors guard against the moving opening appearing in its
own sibling list.

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>
}
