(geometry) The truncation of a polyhedron by replacing each vertex with a face that passes though the midpoint of each edge connected to the vertex; an analogous procedure on a polytope of dimension higher than 3.
A rectified cube is a cuboctahedron – edges reduced to vertices, and vertices expanded into new faces
(geometry) The truncation of a polyhedron by replacing each vertex with a face that passes though the midpoint of each edge connected to the vertex; an analogous procedure on a polytope of dimension higher than 3.
A birectified cube is an octahedron – faces are reduced to points and new faces are centered on the original vertices.
(geometry) The truncation of a polyhedron by replacing each vertex with a face that passes though the midpoint of each edge connected to the vertex; an analogous procedure on a polytope of dimension higher than 3.
A rectified cubic honeycomb – edges reduced to vertices, and vertices expanded into new cells.
