Binary Space Partitioning (BSP) is a method used in computer graphics and computational geometry to divide a space into smaller regions. This technique involves recursively splitting a space using hyperplanes, which are flat surfaces that can be defined in any number of dimensions. Each split creates two distinct regions, allowing for efficient organization and rendering of complex scenes. BSP is particularly useful in 3D rendering and collision detection in video games and simulations. By organizing objects in a hierarchical structure, it enables faster visibility determination and efficient rendering of scenes, as only the visible parts need to be processed, improving overall performance.
