Example with DrawSmoothFacet

Warning: the above example illustrate the macro DrawSmoothFacet that permits to smooth the facets with the GOURAUD algorithm. But that algorithm is really known only by ghostscript. That is why pdf rendering takes sometimes long time (very long time) and not accurate for big images. In that case, it is preferable to get a high resolution jpeg (or an eps export if the document has to stay using ps format).
