Great Stella is the ultimate polyhedron program, letting you create a huge range of polyhedra, rotate them in 3D on-screen, and print nets so you can build your own paper models. Images can be displayed on a polyhedron's faces and printed on the nets (try photos of your pets). Models provided include the uniform polyhedra (Platonic, Archimedean, Kepler-Poinsot, prisms/antiprisms ), Johnson solids, 'Near Misses', Stewart toroids, compounds, geodesic domes, and many more. Duals of all polyhedra are available, and all models can be stellated, faceted, zonohedrified or augmented/excavated/drilled leading to trillions of new polyhedra. See cross-sections, stellation diagrams, etc. Export models as DXF, POV-Ray, VRML, OBJ or OFF, and imported from OFF format. Morph between any polyhedron and its dual using one of six different techniques. And if you have red-blue glasses, you can see it all in 3D. Version 4.2 includes bug fixes and the new 'Display->Show Vertex Angles' feature.
