BoundingBox
From polycount
A Bounding Box is a simplified approximation of the volume of a model, used most commonly for collision detection.
Although it is commonly a box, it can be any shape. If not a box, it is more properly called a bounding volume.
Other common bounding shapes are a sphere (just a radius value), a capsule (basically two radii plus a distance), a cylinder, and a convex polygonal shape.
