About this app

Take polyhedra with you everywhere you go! Rotate them in 3D, explode their faces apart, see their duals and morph polyhedra into their duals in a couple of different ways. Show information such as face, edge and vertex counts, and where available a link to online photographs of paper models made by Robert Webb. A must for fans of polyhedra or sacred geometry.

Includes the following polyhedron categories:

- Platonic Solids: tetrahedron, cube, octahedron, dodecahedron, icosahedron.
- Kepler-Poinsot: the 4 non-convex regular polyhedra.
- Archimedean Solids: the 13 convex but not regular uniform polyhedra.
- Uniform Polyhedra: the remaining 54 non-prismatic non-convex uniform polyhedra.
- Prisms & Antiprisms: a collection of uniform prisms and antiprisms.
- Johnson Solids: 92 non-uniform convex polyhedra with regular faces.
- Near Misses: a collection of polyhedra that almost qualify as Johnson solids.
- Stewart Toroids: non-convex polyhedra with regular faces and holes.
- Compounds: over 80 interesting compounds of polyhedra.
- The 59 Icosahedra: classic collection of stellations of the icosahedron from the book of the same name by Coxeter et. al.
- Stellations: more interesting stellations of other polyhedra.
- Geodesic Spheres: some nice polyhedral approximations to the sphere.
- Waterman Polyhedra: up to root 50.
- and more!

MoStella Gold adds hundreds of other polyhedra including Johnson solids, near misses, stellations, compounds, geodesic spheres, Stewart toroids, etc.

Mark polyhedra as favourites for quick access.

Admire beautiful geometric shapes wherever you go with MoStella!

A great companion for my desk top program Stella. Stella has many more features, such as creating your own stellations, facetings and other polyhedra, and generating nets which you can print to build your own paper models.

Fantastic application using my favorite medium in the field of geometry namely polyhedra or spatial polygons. My only problem is and it may be my ignorance, that I can't determine way to change the polyhedra so that all I can see are the vertices and the axes and it is transparent if I'm missing how to do that please and let me know.

This app is done extremely well, but would it be possible in a future update to fix the hemi-polyhedra's dual-morph-by-triangles animation? They are rather broken.

Very good but a pity the app cannot show or print nets like its brilliant PC version, Stella 4D. Also, cannot make colours partially transparent like the Polyhedra app by David Anniballi (this would help users see pattens inside Steward toroids and other drilled polyhdera).

What's new

- Fixed problems on Lollipop.
- Fixed tap-to-unexplode not always working properly.
- Can now tap to re-explode too.

- Replaced Swipe-to-morph mode with a slider which appears in morph views. Much clearer and more convenient.

- Better rendering on some old devices.
- Put icons beside some buttons.
- Can now zoom when using swipe-to-explode without snapping back together.
