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. |
