A general parallelepiped centered on the origin.
A parallelepiped is a shape having 3 pairs of parallel faces out of which one is parallel with the XY plane (Z faces). All faces are parallelograms in the general case. The Z faces have 2 edges parallel with the X-axis. Note that all angle parameters are expressed in terms of fractions of a 360deg turn.
The shape has the center in the origin and it is defined by:
halfedges: a 3-vector (dY, dY, dZ) with half-lengths of the projections of the edges on X, Y, Z. The lower Z face is positioned at -dZ, and the upper one at +dZ.alpha: angle between the segment defined by the centers of the X-parallel edges and Y axis. Validity range is (-1/4, 1/4);theta: polar angle of the shape's main axis, e.g. the segment defined by the centers of the Z faces. Validity range is [0, 1/4);phi: azimuthal angle of the shape's main axis (as explained above). Validity range is [0, 1).
