Stellations

These stellations are made in the same manner as a foldup polyhedron - but the faces are chosen deliberately (and involve some complicated combinations of polygons) so that a stellated polyhedron is the result, rather than a simple polyhedron

Brief details of how to make sense of a file are contained in this Word document, or click here for a Flash demo (related file moving_Claude1.cg3)giving further details.

Dodecahedron:

1. Constructed by extending edges to meet.  file

2. Constructed as a fold-up. Rather more interesting!  file

Icosahedron:

file 1  This is a foldup icosahedron - important to work out how this was made before trying a stellation

file 2  A foldup of one of the simplest icosahedron stellations

file 3  A stellation diagram. All faces are formed of a subset of the polygons in this diagram (google on Stellations to find out more about this)

file 4  A Kepler-Poinsot polyhedron: the one stellation of the icosahedron which is a regular polyhedron in its own right

file 5  This one folds into other interesting collections of polyhedra

file 6  file 7  file 8  file 9  Further examples

file 10  file 11  These two have rotational, but not reflective, symmetry.
