Dual polyhedron — The dual of a cube is an octahedron, shown here with vertices at the cube face centers … Wikipedia
Conway polyhedron notation — This example chart shows how 11 new forms can be derived from the cube using 3 operations. The new polyhedra are shown as maps on the surface of the cube so the topological changes are more apparent. Vertices are marked in all forms with circles … Wikipedia
Császár polyhedron — An animation of the Császár polyhedron being rotated and unfolded. Type Toroidal polyhedron Faces 14 triangles Edges 21 Verti … Wikipedia
Regular skew polyhedron — In geometry, the regular skew polyhedra are generalizations to the set of regular polyhedron which include the possibility of nonplanar faces or vertex figures.These polyhedra have two forms infinite polyhedra that span 3 space, and finite… … Wikipedia
Infinite skew polyhedron — In geometry, infinite skew polyhedra are an extended definition of polyhedra, created by regular polygon faces, and nonplanar vertex figures.Many are directly related to a convex uniform honeycomb, being the polygonal surface of a honeycomb with… … Wikipedia

Doo–Sabin subdivision surface — Simple Doo Sabin sudivision surface. The figure shows the limit surface, as well as the control point wireframe mesh. In computer graphics, Doo–Sabin subdivision surface is a type of subdivision surface based on a generalization of bi quadratic… … Wikipedia
Duality (mathematics) — In mathematics, a duality, generally speaking, translates concepts, theorems or mathematical structures into other concepts, theorems or structures, in a one to one fashion, often (but not always) by means of an involution operation: if the dual… … Wikipedia
Platonic solid — In geometry, a Platonic solid is a convex polyhedron that is regular, in the sense of a regular polygon. Specifically, the faces of a Platonic solid are congruent regular polygons, with the same number of faces meeting at each vertex; thus, all… … Wikipedia
