Pst-cox is a PSTricks package for drawing 2-dimensional projections of complex regular polytopes (after the work of Coxeter). The package consists of a macro library for drawing the projections. The complex polytopes appear in the study of the root 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 icosahedron) and some infinite series (for example, one can construct a multi-dimensional analogue 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.
