This software displays hundreds of polyhedron and 4D polytopes, including all 1849 uniform 4D polytopes. It allows users to rotate and print nets for paper models, and customize with photos. It also enables creation of new polyhedra and exporting of models.

Stella4D allows you to rotate your creations in 3D and print nets to make your own paper polyhedron models. Put your favorite photos on the faces of your polyhedra and create new ones using stellation, faceting, zonohedra, dual-morphing, and augmentation. You can also watch 3D cross-sections of 4D polychora morphing as the slicing hyperplane cuts deeper through the polytope.
One of the best features of Stella4D is that it allows you to see 4D polytopes projected into 3D, rotate them in 4D, and see their 3D nets, making it easy to understand complex mathematical concepts. Moreover, you can export your designs to 3D formats, making it easy to share your creations with others. Lastly, if you have red-blue glasses, you can enjoy all the wonders of Stella4D in true 3D. Built on the much-celebrated Great Stella, Stella4D adds the four-dimension to the equation, making it an indispensable tool for professionals and hobbyists alike.
