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