WebA quad tree is a tree data structure used in spatial partitioning, so that it's easy to traverse and search. You may be wondering what exactly is spatial partitioning? To put it in simple … WebQuadTree. A C# QuadTree implementation specifically designed for testing AABB collisions in 2D space. What does it do? A QuadTree is a way of partitioning 2D space by recursively subdividing it into quads. This implementation allows you to insert rectangles into a QuadTree and check for collisions against them.

Quadtrees may be classified according to the type of data they represent, including areas, points, lines and curves. Quadtrees may also be classified by whether the shape of the tree is independent of the order in which data is processed. The following are common types of quadtrees.
