Table 2 GC Operation

A standard (method 1) 8-frequency geodesic division of an icosahedron. gcopoly.py icosahedron.off -a 8 | off_color -f C | antiview -R 90,0,0	(4,3) GC operation on a cube, in canonical form. gcopoly.py cube.off -a 4 -b 3 | canonical | off_color -f C| antiview -R 90,0,0
Standard (method 1) (5,3) subdivision of a tetrahedron. (Notice the vertices in the upper left and lower right.) gcopoly.py tetrahedron.off -a 5 -b 3 | off_color -f G | antiview -R 90,0,0	(5,3) subdivision of a tetrahedron, but using nslerp projection and optimized to reduce variation in face area. gcopoly.py tetrahedron.off -a 5 -b 3 -p nslerp -k faces | off_color -f G | antiview -R 90,0,0
Conway’s Game of Life on the surface of a (5,3) subdivided cube. Courtesy of Roger Kaufman.	Repeatedly applying the (1,1) triangular subdivision using the flat projection and not normalizing gives this interesting organic shape. It resembles a viral capsid (moreso than geodesic polyhedra usually resemble a viral capsid), or a strange fruit. Produced by gcopoly.py icosahedron.off -a 9 -n -f |antiview: -a 7 and -a 5 -b 3 are similar.
Improper geodesic polyhedron on the 3-dihedron. Note dangling faces. gcopoly.py 4dihedron.off -a 5 -b 3 -p nslerp -k energy | off_color -f C | antiview -R 90,90,0	GC operation on the 4-dihedron. gcopoly.py 4dihedron.off -a 5 -b 3 -p nslerp -k energy | off_color -f C | antiview -R 90,45,0
