Rectification has the following technical meanings:

Mathematics

Rectification (geometry) In Euclidean geometry, rectification, also known as critical truncation or complete-truncation, is the process of truncating a polytope by marking the midpoints of all its edges, and cutting off its vertices at those points. The resulting p ...
