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); // /////////////////////////////////////////////////////////////////////////////// #ifndef G4TessellatedSolid_hh #define G4TessellatedSolid_hh 1 #include "G4VSolid.hh" #include "G4VFacet.hh" #include "G4VGraphicsScene.hh" #include "G4VPVParameterisation.hh" #include "G4VPhysicalVolume.hh" #include "G4VoxelLimits.hh" #include "G4AffineTransform.hh" #include "G4VisExtent.hh" #include "globals.hh" #include #include #include #include class G4TessellatedSolid : public G4VSolid { public: // with description G4TessellatedSolid ();
