Detailed Description

Class representing 3D range or axis aligned bounding box.

Stored as minimum and maximum extent corners. Alternate representation would be center and dimensions. May be empty or nonempty. For nonempty bounds, minimum <= maximum has to hold for all axes. Empty bounds have to be represented as minimum = PX_MAX_BOUNDS_EXTENTS and maximum = -PX_MAX_BOUNDS_EXTENTS for all axes. All other representations are invalid and the behavior is undefined.
