So, you will become more familiar with the polyhedrons, and you may enjoy these abstract solids as fascinating formative arts. The main advantage of this app is that it offers a large variety of polyhedral compounds of identical uniform star polyhedra and their duals. By choosing a model, and by setting colors and parameters optionally, you will find various types of 3d shapes including wonderful shapes, mysterious artistic shapes, and strange eccentric shapes, which will be interesting for you. Features: - Swipe or touch gesture will rotate, zoom or move the object. So, you can observe it from various angles or positions. (You can observe it even from inside.) - Switches between showing and hiding each face of the polyhedron, and switches between showing and hiding each component of the compound - Function to display the edges of the polyhedra with selectable thickness and color - For each kepler-poinsot polyhedron, each uniform star polyhedron and each dual of uniform star polyhedron, the app can provide the compound from 14 to 22 kinds (more than 1200 in total). - Many color patterns for the faces of the polyhedron. - Functions to display basic informations about the polyhedron, and to access the wikipedia sites about the related items - Slider controllers to reduce z-fighting (screen flicker) - Save PNG images to camera roll
