Stella (software)

Stella (software)

Stella, a computer program available in three versions (Great Stella, Small Stella and Stella4D) was created by Robert Webb of Australia. The programs contain a large library of polyhedra which can be manipulated and altered in various ways.

Polyhedra in Great Stella's library include the Platonic Solids, the Archimedean solids, the Kepler-Poinsot solids, the Johnson solids, some Johnson Solid near-misses, numerous compounds including the uniform polyhedra, and other polyhedra too numerous to list here. Operations which can be performed on these polyhedra include stellation, faceting, augmentation, dualization (also called "reciprocation"), creating convex hulls, and others.

All versions of the program enable users to print nets for polyhedra. These nets may then be assembled into actual three-dimensional polyhedral models of great beauty and complexity.

In 2007, a Stella4D version was added, allowing the generation and display of four dimensional polytopes (polychora), including a library of all convex uniform polychora, and all currently known nonconvex star polychora, as well as the uniform duals. They can be selected from a library or generated from user created polyhedral vertex figure files.
