Binary Space Partitioning

It is used in collision.

Binary space partitioning. The resulting data structure is a binary tree and the two subplanes are referred to as front and back. Since there is no restriction on what hyperplanes are used polytopes polyhedra polygons etc can be represented exactly. Binary space partitioning is a generic process of recursively dividing a scene into two until the partitioning. In this case the constraint is the width and height of the container and the fact that we do not want containers to overlap since they represent separate rooms.

A partitioning tree is the recording of this process of recursive subdivision in the form of a binary tree of hyperplanes. Bsp uses tree data structure to store information about set of objects in each convex set. It can be seen as a generalisation of other spatial tree structures such as k d trees and quadtrees one where hyperplanes that partition the space may have any orientation rather than being aligned with the coordinate axes as they are in k d trees or quadtrees. Binary space partitioning is a method of recursively subdividing a space into convex sets using hyper planes.

A tutorial on binary space partitioning trees inproceedings naylor2001ato title a tutorial on binary space partitioning trees author b. Generating a bsp tree can be time consuming. Binary space partitioning overview of bsp. Bsp does not solve the problem of visible surface.

Binary space partitioning is a technique for recursively dividing a space subject to some constraints. Binary space partitioning contents. Binary space partitioning trees is a method of recursively subdividing a space into two convex sets by using hyperplanes as partitions. I immediately thought of binary space partitioning as a way to produce this sort of layout.

Binary space partitioning is a generic process of recursively dividing a scene into two until the partitioning satisfies one or more requirements. Binary space partitioning is treated as a generic process of recursively dividing a scene into two. There s a pretty good description of bsp here as video or if you happen to have a copy of procedural generation in game design there s a great chapter in there by brian bucklew on space partitioning of various kinds including binary.
