An explicit guide to the geometric principles, design, and construction of complex polyhedral figuresThese stars can assume other shapes as well, but only these are mentioned here because only these appear again later in this book. ... to the octahedron so that the faces they share internally melt away, leaving all the interior hollow, you have a non-convex polyhedron. ... If you turn now to the dodecahedron and produce each facial plane you will find that it leads to the formation of three distinct types ofanbsp;...
