51 | // The G4QuadrangularFacet class is used for the contruction of |
---|
52 | // G4TessellatedSolid. |
---|
53 | // It is defined by four vertices, which shall be in the same plane and be |
---|
54 | // supplied in anti-clockwise order looking from the outsider of the solid |
---|
55 | // where it belongs. Its constructor |
---|
56 | // |
---|
57 | // G4QuadrangularFacet (const G4ThreeVector Pt0, const G4ThreeVector vt1, |
---|
58 | // const G4ThreeVector vt2, const G4ThreeVector vt3, |
---|
59 | // G4FacetVertexType); |
---|
60 | // |
---|
61 | // takes 5 parameters to define the four vertices: |
---|
62 | // 1) G4FacetvertexType = "ABSOLUTE": in this case Pt0, vt1, vt2 and vt3 |
---|
63 | // are the four vertices required in anti-clockwise order when looking |
---|
64 | // from the outsider. |
---|
65 | // 2) G4FacetvertexType = "RELATIVE": in this case the first vertex is Pt0, |
---|
66 | // the second vertex is Pt0+vt, the third vertex is Pt0+vt2 and |
---|
67 | // the fourth vertex is Pt0+vt3, in anti-clockwise order when looking |
---|
68 | // from the outsider. |
