Announcement text: ---------------------------------------------------------------------- We have wrote a new package for PSTricks for drawing 2 dimensional projection of complex regular polyopes (after the work of Coxeter).

The package consists in a library of macro for drawing the projections. The complex polytopes appears in the study of the roots systems and play a crucial role in many domains related to mathematics and physics. These polytopes have been completely described by Coxeter in his book Regular Complex Polytopes. there exist only a finite numbers of exceptional regular complex polytopes (for example the ikosae dron) and some infinite series (for example, one can construct multi-dimensional analogous of the hypercube in any -finite- dimension). The library contains two packages. The first, pst-coxcoor, is devoted to the exceptional complex regular polytopes whose coordinates have been pre-computed. The second, pst-coxeterp, is devoted to the infinite series.

One can find also other informations in the beautiful page of Jean-Michel Sarlat: http://melusine.eu.org/syracuse/pstricks/pst-cox/
