Crystallographic Space Groups: Representation and Interactive Visualization by Geometric Algebra

Authors: Eckhard Hitzer, Christian Perwass

We treat the symmetries of crystal space lattices in geometric algebra (GA)~\cite{DH:PGSG}. All crystal cell point groups are generated by geometric multiplication of two or three physical cell vectors. Only one or two relative angles subtended by these vectors need to be known. This treatment extends to space groups by including translations. GA helps to identify optimal multivector generators. As example we take the monoclinic case. New free interactive OpenGL and GA based software visualizes these symmetries.
