<h3>3D Straight Skeleton and Polyhedron Offsetting</h3>
In 3-dimensional space, an offset of a polyhedron is computed by<br />
shifting all facets inwards while keeping them parallel to their<br />
initial orientation. By following the moving vertices,<br />
the straight skeleton is revealed.<br />
The moving edges divide the polyhedron into cells<br />
with useful geometric properties, such as monotonicity.
Compared to straight skeletons of polygons in the plane,<br />
computing initial offsets is different: In the very first moment,<br />
vertices of degree greater than three have to be split.
