PlaneGroups 1.1

(page last modified September 2,1996)

This program displays two-dimensional wallpaper-type patterns by using the symmetry operations of the 17 crystallographic spacegroups of the plane. To create a pattern you can use the integrated motif editor for drawing a structural unit, which is then used to build up the pattern by selecting a plane group.
