Transformations in the geom3d Package
A mapping of a set A onto a set B is one in which distinct elements of A have distinct images in B is called a transformation (or one-to-one mapping) of A onto B.
The following elementary transformations are implemented in the geom3d package:
Direct isometries: rotation, translation, ScrewDisplacement
Opposite isometries: reflection, RotatoryReflection, GlideReflection
Non-isometric similarity: homothety, homology
