// Class description:
//
// G4TessellatedSolid is a special Geant4 solid defined by a number of
// facets (G4VFacet). It is important that the supplied facets shall form a
// fully enclose space which is the solid.
// At the moment only two types of facet can be used for the construction of
// a G4TessellatedSolid, i.e. the G4TriangularFacet and G4QuadrangularFacet.
//
// How to contruct a G4TessellatedSolid:
//
// First declare a tessellated solid:
//
// G4TessellatedSolid* solidTarget = new G4TessellatedSolid("Solid_name");
//
// Define the facets which form the solid
//
// G4double targetSiz = 10*cm ;
// G4TriangularFacet *facet1 = new
// G4TriangularFacet (G4ThreeVector(-targetSize,-targetSize, 0.0),
// G4ThreeVector(+targetSize,-targetSize, 0.0),
// G4ThreeVector( 0.0, 0.0,+targetSize),
// ABSOLUTE);
// G4TriangularFacet *facet2 = new
// G4TriangularFacet (G4ThreeVector(+targetSize,-targetSize, 0.0),
// G4ThreeVector(+targetSize,+targetSize, 0.0),
// G4ThreeVector( 0.0, 0.0,+targetSize),
// ABSOLUTE);
// G4TriangularFacet *facet3 = new
// G4TriangularFacet (G4ThreeVector(+targetSize,+targetSize, 0.0),
// G4ThreeVector(-targetSize,+targetSize, 0.0),
// G4ThreeVector( 0.0, 0.0,+targetSize),
// ABSOLUTE);
// G4TriangularFacet *facet4 = new
// G4TriangularFacet (G4ThreeVector(-targetSize,+targetSize, 0.0),
// G4ThreeVector(-targetSize,-targetSize, 0.0),
// G4ThreeVector( 0.0, 0.0,+targetSize),
// ABSOLUTE);
// G4QuadrangularFacet *facet5 = new
// G4QuadrangularFacet (G4ThreeVector(-targetSize,-targetSize, 0.0),
// G4ThreeVector(-targetSize,+targetSize, 0.0),
// G4ThreeVector(+targetSize,+targetSize, 0.0),
// G4ThreeVector(+targetSize,-targetSize, 0.0),
// ABSOLUTE);
//
// Then add the facets to the solid:
//
// solidTarget->AddFacet((G4VFacet*) facet1);
// solidTarget->AddFacet((G4VFacet*) facet2);
// solidTarget->AddFacet((G4VFacet*) facet3);
// solidTarget->AddFacet((G4VFacet*) facet4);
// solidTarget->AddFacet((G4VFacet*) facet5);
//
// Finally declare the solid is complete:
//
// solidTarget->SetSolidClosed(true);
