Procrustes transformation

A Procrustes transformation is a geometric transformation that involves only translation, rotation, uniform scaling, or a combination of these transformations. Hence, it may change the size or position, but not the shape of a geometric object.

Named after the mythical Greek robber, Procrustes, who made his victims fit his bed either by stretching their limbs or cutting them off.
