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.

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

Authoritative multiplayer snake server with WebSocket AOI snapshots and spatial hashing

2D Spatial Hash Grid

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

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.

Particle physics engine written entirely using rust and ggez!

Efficient, thread-safe 2D spatial hashing for Go

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.
