Detailed Description

Represents an oriented bounding box.

As a center point, extents(radii) and a rotation. i.e. the center of the box is at the center point, the box is rotated around this point with the rotation and it is 2*extents in width, height and depth. Box geometry

The rot member describes the world space orientation of the box. The center member gives the world space position of the box. The extents give the local space coordinates of the box corner in the positive octant. Dimensions of the box are: 2*extent. Transformation to world space is: worldPoint = rot * localPoint + center Transformation to local space is: localPoint = T(rot) * (worldPoint - center) Where T(M) denotes the transpose of M.
