Bounding volume (solid shore, volume limiting) in 3D computer block in a simplified way of representing the smallest space in which all data objects are located. They are used, for example, to simplify the collision detection and visibility of the screen to check in their facilities, so that the lumps can be simplified a lot faster and easier to perform collision tests. Objects in 3D graphics are composed of individual polygons. Collision checking each of the thousands of polygons, with the first object of the polygons of the second object takes a long time, so in checking the collision of two objects, first check whether the bounding volume is a collision, and if not
