The quadtree is the two-dimensional case of a broader family of space-partitioning data structures. Octrees extend the same idea to three dimensions (splitting cubes into eight children), KD-trees use alternating axis-aligned splits (splitting along x, then y, then x again), and R-trees group nearby objects into bounding rectangles. Each variant makes different tradeoffs between construction time, query speed, and update cost.
It’s also possible to abandon the threshold matrix altogether and instead calculate a value for every pixel coordinate at runtime. If the function is simple enough this can be a good and efficient way to break up patterns and create interesting textures.
