OBBox

Inherited: None

Description

An arbitrarily oriented bounded volume in space in the form of a rectangular parallelepiped (Bounding Box). Unlike AABB, OBB rotates with the object and does not change its size. Collision testing with OBB is somewhat more complicated and slower than AABB, but more often it is more preferable. Oriented Bounding Box represented by center of box, size and rotation quaternion.
