// Class Description:
// G4Polyhedron is an intermediate class between G4 and visualization
// systems. It is intended to provide some service like:
//   - polygonization of the G4 shapes with triangulization
//     (quadrilaterization) of complex polygons;
//   - calculation of normals for faces and vertices.
//
// Inherits from HepPolyhedron, to which reference should be made for
// functionality.
//
// Public constructors:
//   G4PolyhedronBox(dx,dy,dz)            - create G4Polyhedron for G4 Box;
//   G4PolyhedronTrd1(dx1,dx2,dy,dz)      - create G4Polyhedron for G4 Trd1;
//   G4PolyhedronTrd2(dx1,dx2,dy1,dy2,dz) - create G4Polyhedron for G4 Trd2;
//   G4PolyhedronTrap(dz,theta,phi,
//                    h1,bl1,tl1,alp1,
//                    h2,bl2,tl2,alp2)    - create G4Polyhedron for G4 Trap;
//   G4PolyhedronPara(dx,dy,dz,
//                    alpha,theta,phi)    - create G4Polyhedron for G4 Para;
//
//   G4PolyhedronTube(rmin,rmax,dz)       - create G4Polyhedron for G4 Tube;
//   G4PolyhedronTubs(rmin,rmax,dz,
//                    phi1,dphi)          - create G4Polyhedron for G4 Tubs;
//   G4PolyhedronCone(rmin1,rmax1,
//                    rmin2,rmax2,dz)     - create G4Polyhedron for G4 Cone;
//   G4PolyhedronCons(rmin1,rmax1,
//                    rmin2,rmax2,dz,
//                    phi1,dphi)          - create G4Polyhedron for G4 Cons;
//
//   G4PolyhedronPgon(phi,dphi,npdv,nz,
//                    z(*),rmin(*),rmax(*)) - create G4Polyhedron for G4 Pgon;
//   G4PolyhedronPcon(phi,dphi,nz,
//                    z(*),rmin(*),rmax(*)) - create G4Polyhedron for G4 Pcon;
//
//   G4PolyhedronSphere(rmin,rmax,
//                      phi,dphi,the,dthe)  - create G4Polyhedron for Sphere;
//   G4PolyhedronTorus(rmin,rmax,rtor,
//                     phi,dphi)            - create G4Polyhedron for Torus;
//   G4PolyhedronEllipsoid(dx,dy,dz,
//                     zcut1,zcut2)         - create G4Polyhedron for Ellipsoid;
//
// Public functions inherited from HepPolyhedron (this list might be
// incomplete):
//   GetNoVertices()  - returns number of vertices
//   GetNoFacets()    - returns number of faces
//   GetNextVertexIndex(index, edgeFlag) - get vertex indeces of the
//                      quadrilaterals in order; returns false when

//   GetVertex(index) - returns vertex by index;

//   GetNextNormal(normal) - get normals of each face in order;
//                      returns false when finished all faces;
//   GetNextUnitNormal(normal) - get normals of unit length of each face
//                      in order; returns false when finished all faces;
//   GetNextEdgeIndeces(i1, i2, edgeFlag) - get indeces of the next edge;
//                      returns false for the last edge;
//   GetNextEdge(p1, p2, edgeFlag) - get next edge;
//                      returns false for the last edge;
//   SetNumberOfRotationSteps(G4int n) - Set number of steps for whole circle;

// History:
// 21st February 2000  Evgeni Chernaev, John Allison
// - Re-written to inherit HepPolyhedron.
//
// 11.03.05 J.Allison
// - Added fNumberOfRotationStepsAtTimeOfCreation and access method.
//   (NumberOfRotationSteps is also called number of sides per circle or
//   line segments per circle - see
//   /vis/viewer/set/lineSegmentsPerCircle.)
// 20.06.05 G.Cosmo
// - Added G4PolyhedronEllipsoid.
// 09.03.06 J.Allison
// - Added operator<<.
