Octrees

An octree is a data structure used to organize 3D space efficiently. Imagine dividing a large cube into eight equal smaller cubes; each of these can then be further subdivided into eight smaller cubes, and so on. This recursive division helps manage complex 3D data, like graphics or spatial information, by allowing quick access to specific regions. Octrees are especially useful in computer graphics, gaming, and simulations for efficiently rendering scenes, managing collision detection, or storing spatial data, by reducing the amount of data processed at each step.
