Questions tagged [bounding-box]

A Bounding Box is the smallest box that encloses a geometry. There are two common classes of Bounding Boxes that are employed: Oriented Bounding Boxes (OBB), and an Axis-Aligned Bounding Boxes (AABB). Bounding boxes are commonly employed as a cheap way to approximate more complex geometries in a range of applications, including collision detection.
