Welcome to the space group web site!
The latest (6. September 2010):
A new release version (2.3.0) of the SpaceGroupVisualizer is now available. This version fixes the problem “.NET feature not licenced” that you may have experienced when starting the SGV.
On these pages we present software and publications that treat crystallographic space and point groups using Geometric Algebra. The algebra allows us to represent symmetries without the need to refer to a particular basis or origin. This method to describe point and space groups was first introduced by David Hestenes.
Eckhard Hitzer and Christian Perwass worked on visualising point and space groups using the visualisation tool CLUCalc.This software implements Geometric Algebra, which allows for a direct implementation of symmetry operators in the algebra. Follow the links above to download publications and software for the different topics.
In particular note the space group visualisation project, which started at the end of 2005. By now (Jan. 2010) the first release version is available.
We would be glad to hear your comments and suggestions. Just send us an email to help_at_spacegroup.info.
