About
Performance at Scale
Spatial indexing and world streaming for large-scale building systems.
Quick Start
import { SpatialHashGrid } from './scripts/spatial-hash-grid.js';
import { Octree } from './scripts/octree.js';
// Uniform distribution - use hash grid
const grid = new SpatialHashGrid(10);
grid.insert(piece, piece.position);
const nearby = grid.queryRadius(position, 15);
// Clustered bases - use octree
const octree = new Octree(bounds, { maxDepth: 8 });
octree.insert(piece);
const inBox = octree.queryBox(min, max);Reference
See references/performance-at-scale.md for detailed guidance on:
- Spatial partitioning selection (when to use grid vs octree)
- Chunk loading strategies
- Instancing and LOD
- Memory management
