spatial-hash

Find nearby 3D objects in constant time O(1).

Spatial hashing for Unity using ECS/DOTS

An opinionated 2D sparse grid made for use with Bevy. For storing and querying entities

Spatial hashing for broadphase collision detection

A simple and fast C# spatial hash implementation

An implementation of spatial hashing for 2D collisions for the PICO-8.

Simple JS physics simulation with colliding primitives, that uses a spatial hash for efficiency

2D Spatial Hash Grid that extends Map

🚀 High-performance, generic Spatial Hash for Unity. Architected for O(1) performance, zero allocations, and data-oriented simplicity. Includes multi-part masterclass tutorial.

A Swift implementation (Swift Package) of the Boids algorithm, optimised using Spatial Hash ( & Quad Tree) and Tasks (Actors) for a faster and lightweight simulation.

Quadtree implementation (updated for java 8, properly uses generics)

2D Spatial Hash Grid

Cover point generation, constant-time scoring and exclusive reservation for Unreal Engine 5 AI - measured peek-left/right/over against the real level, a spatial hash instead of line traces per candidate, and claim/release so two agents never share one point. Tactical shooter cover system.

Authoritative multiplayer snake server with WebSocket AOI snapshots and spatial hashing

Broad-phase 2D collision detection: comparing naive O(n²) pairwise checks against spatial hash grid and quadtree spatial partitioning algorithms.

Spring-based DOM animation with velocity handoff. Magnetic hover, draggable cards, Tinder-style swipe. Shared ticker, zero rAF spam.

3D Chaos Engine is a lightweight, pure C++ Win32/GDI interactive fractal tree simulator. It renders procedural 3D branching patterns in real-time with continuous camera controls, dynamic spatial grid collision detection, customizable growth parameters, and custom color palettes.

A browser-based ecosystem simulator where every keystroke spawns a procedurally generated organism. Type characters to create creatures with unique DNA, watch them hunt, flock, reproduce, and survive. Punctuation triggers dramatic world events — earthquakes, rain, gravity wells, slow-motion.

Efficient, thread-safe 2D spatial hashing for Go

Particle physics engine written entirely using rust and ggez!
