<DIV><FONT size=2><FONT size=3> We have wrote a new package for PSTricks
for drawing 2 dimensional<BR>projection of complex regular polyopes (after the
work of Coxeter).<BR><BR>The package consists in a library of macro for drawing
the<BR>projections. The complex polytopes appears in the study of the
roots<BR>systems and play a crucial role in many domains related
to<BR>mathematics and physics. These polytopes have been completely<BR>described
by Coxeter in his book "Regular Complex Polytopes". there<BR>exist only a finite
numbers of exceptional regular complex polytopes<BR>(for example the ikos\ae
dron) and some infinite series (for<BR>example, one can construct
multi-dimensional analogous of the<BR>hypercube in any -finite- dimension). The
library contains two<BR>packages. The first, pst-coxcoor, is devoted to the
exceptional<BR>complex regular polytopes whose coordinates have been
pre-computed.<BR>The second, pst-coxeterp, is devoted to the infinite
series.<BR></FONT></FONT></DIV>
