VRML general position diagrams of the magnetic subperiodic groups

The standard representation of the general position diagrams of the non-magnetic subperiodic groups, i.e. frieze, rod and layer groups, are two-dimensional (International Tables for Crystallography, 2002, and references therein). For rod and layer groups these are two-dimensional projections of three-dimensional diagrams. With this program, we have developed three-dimensional general position diagrams of all magnetic subperiodic groups, which includes all non-magnetic cases. Each diagram can be rotated and zoomed to aid in the visualization of the general position diagram and includes both the general positions of the atoms and the general orientations of the associated magnetic moments.
