Each solid on this page was created by applying the
operation to one of the Archimedean solids. Rectification is a form of
truncation where each vertex is truncated up to the midpoints of the edges
meeting at that vertex. This operation is typically applied to one of the
Platonic solids, but it can also be applied to a non-regular polyhedron as
long as the midpoints of the edges meeting at each vertex are coplanar.
If the non-regular polyhedron is convex, then the resulting polyhedron
will not intersect itself.
