Quad and Oct Trees (Octree) are balanced tree data structures which can be used to greatly speed up the performance of your program. By partitioning your data spatially, these trees allow for quick exclusion of parts of your data allowing for your algorithm to complete sooner. Knowing when and how to use trees is an essential part of computer science.
