38 * SoPolyhedron is an Inventor encapsulation of the G4Polyedron
39 * class written by E.Chernyaev. In particular SoPolyhedron permits
40 * to represent boolean operations over solids.
41 * To avoid clashes with other libraries (Geant4) where the G4Polyhedron
42 * classes may be found, the G4Polyhedron (through usage of CPP macros)
43 * had been renamed G4Polyhedron in the HEPVis lib.
44 * The solids are modeled with G4Polyedron objects. The G4Polyhedron
45 * permits to produce a new G4Polyhedron according to the boolean
46 * operation done on them. The resulting G4Polyhedron is then given
47 * to an SoPolyhedron for rendering.
48 * Note that a boolean operation could be rendered in wire frame
49 * by drawing the contour of the resulting solid (not by drawing
50 * the wire frame of a triangulation).
51 * See the applications/Polyhedron example.
