OBB

Oriented Bounding Box | oriented bounding parallelepiped
The area in the space surrounding a certain object, in the form of rectangular parallelepiped, which rotates with the object. Used in various geometric operations, replacing the object itself in order to simplify and accelerate the computing - for example, if the clashes, the layout of the rays and the partitioning of space. Has the advantage over the AABB, consisting of the same degree of approximation in any rotating object.
