Detailed Description

Describes a bounding box in 3D space.
A bounding box is parallel to the axes of the coordinates
system. If it is finite, it is defined by the three intervals:

[ Xmin,Xmax ],
[ Ymin,Ymax ],
[ Zmin,Zmax ].
A bounding box may be infinite (i.e. open) in one or more
directions. It is said to be:
OpenXmin if it is infinite on the negative side of the "X Direction";
OpenXmax if it is infinite on the positive side of the "X Direction";
OpenYmin if it is infinite on the negative side of the "Y Direction";
OpenYmax if it is infinite on the positive side of the "Y Direction";
OpenZmin if it is infinite on the negative side of the "Z Direction";
OpenZmax if it is infinite on the positive side of the "Z Direction";
WholeSpace if it is infinite in all six directions. In this
case, any point of the space is inside the box;
Void if it is empty. In this case, there is no point included in the box.
A bounding box is defined by:
six bounds (Xmin, Xmax, Ymin, Ymax, Zmin and
Zmax) which limit the bounding box if it is finite,
eight flags (OpenXmin, OpenXmax, OpenYmin,
OpenYmax, OpenZmin, OpenZmax,
WholeSpace and Void) which describe the
bounding box if it is infinite or empty, and
a gap, which is included on both sides in any direction
when consulting the finite bounds of the box.
