The Legos and Surfaces painter class.

3D graphics representations package.

This package was originally written by Evgueni Tcherniaev from IHEP/Protvino.

The original Fortran implementation was adapted to HIGZ/PAW by Olivier Couet and Evgueni Tcherniaev.

This class is a subset of the original system. It has been converted to a C++ class by Rene Brun.
