| 54 | // G4TessellatedSolid is a special Geant4 solid defined by a number of |
---|
| 55 | // facets (G4VFacet). It is important that the supplied facets shall form a |
---|
| 56 | // fully enclose space which is the solid. |
---|
| 57 | // At the moment only two types of facet can be used for the construction of |
---|
| 58 | // a G4TessellatedSolid, i.e. the G4TriangularFacet and G4QuadrangularFacet. |
---|
| 59 | // |
---|
| 60 | // How to contruct a G4TessellatedSolid: |
---|
| 61 | // |
---|
| 62 | // First declare a tessellated solid: |
---|
| 63 | // |
---|
| 64 | // G4TessellatedSolid* solidTarget = new G4TessellatedSolid("Solid_name"); |
---|
| 65 | // |
---|
| 66 | // Define the facets which form the solid |
---|
| 67 | // |
---|
| 68 | // G4double targetSiz = 10*cm ; |
---|
| 69 | // G4TriangularFacet *facet1 = new |
---|
| 70 | // G4TriangularFacet (G4ThreeVector(-targetSize,-targetSize, 0.0), |
---|
| 71 | // G4ThreeVector(+targetSize,-targetSize, 0.0), |
---|
| 72 | // G4ThreeVector( 0.0, 0.0,+targetSize), |
---|
| 73 | // ABSOLUTE); |
---|
| 74 | // G4TriangularFacet *facet2 = new |
---|
| 75 | // G4TriangularFacet (G4ThreeVector(+targetSize,-targetSize, 0.0), |
---|
| 76 | // G4ThreeVector(+targetSize,+targetSize, 0.0), |
---|
| 77 | // G4ThreeVector( 0.0, 0.0,+targetSize), |
---|
| 78 | // ABSOLUTE); |
---|
| 79 | // G4TriangularFacet *facet3 = new |
---|
| 80 | // G4TriangularFacet (G4ThreeVector(+targetSize,+targetSize, 0.0), |
---|
| 81 | // G4ThreeVector(-targetSize,+targetSize, 0.0), |
---|
| 82 | // G4ThreeVector( 0.0, 0.0,+targetSize), |
---|
| 83 | // ABSOLUTE); |
---|
| 84 | // G4TriangularFacet *facet4 = new |
---|
| 85 | // G4TriangularFacet (G4ThreeVector(-targetSize,+targetSize, 0.0), |
---|
| 86 | // G4ThreeVector(-targetSize,-targetSize, 0.0), |
---|
| 87 | // G4ThreeVector( 0.0, 0.0,+targetSize), |
---|
| 88 | // ABSOLUTE); |
---|
| 89 | // G4QuadrangularFacet *facet5 = new |
---|
| 90 | // G4QuadrangularFacet (G4ThreeVector(-targetSize,-targetSize, 0.0), |
---|
| 91 | // G4ThreeVector(-targetSize,+targetSize, 0.0), |
---|
| 92 | // G4ThreeVector(+targetSize,+targetSize, 0.0), |
---|
| 93 | // G4ThreeVector(+targetSize,-targetSize, 0.0), |
---|
| 94 | // ABSOLUTE); |
---|
| 95 | // |
---|
| 96 | // Then add the facets to the solid: |
---|
| 97 | // |
---|
| 98 | // solidTarget->AddFacet((G4VFacet*) facet1); |
---|
| 99 | // solidTarget->AddFacet((G4VFacet*) facet2); |
---|
| 100 | // solidTarget->AddFacet((G4VFacet*) facet3); |
---|
| 101 | // solidTarget->AddFacet((G4VFacet*) facet4); |
---|
| 102 | // solidTarget->AddFacet((G4VFacet*) facet5); |
---|
| 103 | // |
---|
| 104 | // Finally declare the solid is complete: |
---|
| 105 | // |
---|
| 106 | // solidTarget->SetSolidClosed(true); |
