14\ingroup Shapes_classes
15\brief Parallelepiped class.
16
17A parallelepiped is a shape having 3 pairs of parallel faces out of
18which one is parallel with the XY plane (Z faces). All faces are
19parallelograms in the general case. The Z faces have 2 edges parallel
20with the X-axis.
21
22The shape has the center in the origin and it is defined by:
23
24 - dX, dY, dZ: half-lengths of the projections of the edges on X, Y
25 and Z. The lower Z face is positioned at -dZ, while the upper at +dZ.
26 - alpha: angle between the segment defined by the centers of the
27 X-parallel edges and Y axis [-90,90] in degrees
28 - theta: theta angle of the segment defined by the centers of the Z faces;
29 - phi: phi angle of the same segment

35A box is a particular parallelepiped having the parameters:
