Stellated polyhedron wikipedia
In geometry, stellation is the process of extending a polygon in two dimensions, polyhedron in three dimensions, or, in general, a polytope in n dimensions to form a new figure. Starting with an original figure, the process extends specific elements such as its edges or face planes, usually in a symmetrical way, … 查看更多內容 In 1619 Kepler defined stellation for polygons and polyhedra as the process of extending edges or faces until they meet to form a new polygon or polyhedron. He stellated the regular dodecahedron to obtain two … 查看更多內容 A polyhedron is stellated by extending the edges or face planes of a polyhedron until they meet again to form a new polyhedron or compound. The interior of the new polyhedron is divided by the faces into a number of cells. The face planes of a polyhedron may … 查看更多內容 The first systematic naming of stellated polyhedra was Cayley's naming of the regular star polyhedra (nowadays known as the 查看更多內容 Alongside from his contributions to mathematics, Magnus Wenninger is described in the context of the relationship of 查看更多內容 Stellating a regular polygon symmetrically creates a regular star polygon or polygonal compound. These polygons are characterised by the number of times m that the … 查看更多內容 The stellation process can be applied to higher dimensional polytopes as well. A stellation diagram of an n-polytope exists in an (n − 1)-dimensional hyperplane of a given 查看更多內容 Wenninger noticed that some polyhedra, such as the cube, do not have any finite stellations. However stellation cells can be constructed as prisms which extend to infinity. The … 查看更多內容 網頁Category:Polyhedral stellation. Category. : Polyhedral stellation.
