Spatial index library with R*Tree, STR-Tree, Quadtree, CritBit, KD-Tree, CoverTree and PH-Tree

Quadtree implementation

Library that helps to implement the QuadTree in android, by using splitting images

Small project showing the power of the quadtree structure to improve geolocation

Hybrid Spatial Data Structure based on Quad Tree, R Tree and KD Tree for insertion, search and finding the nearest neighbours on a 2D plane

Particle collision with quad-tree experiment inspired by games like Eufloria and Auralux.

A quadtree written in Java. Supports insert, update, search, remove, and more! Plenty of unit tests and also a performance report to compare with a brute force method.

A simulation of the boids flocking algorithm combined with a simple ecosystem that uses quadtree (Written in java)

This is a utility program to test whether Spatial Hashing or Quad Trees have a faster overall performance and helping a programmer make a choice between the two algorithms. This includes a result visualizer, timing logger, and other similar tools.

ECS module for Java.

Quadtree and AABB (Axis-Aligned Bounding Box) implementation

A simulation of flocking behaviors seen in nature written in Java with Processing

Binary index for areas spatial search using quad tree

Example implementation of the IF2 specifications of the European CEF project Intercor

Quad Tree implementation in java

This is a simple implementation of the QuadTree data structure in Java.
