31 // Class G4QuadrangularFacet
32 //
33 // Class description:
34 //
35 // The G4QuadrangularFacet class is used for the contruction of
36 // G4TessellatedSolid.
37 // It is defined by four fVertices, which shall be in the same plane and be
38 // supplied in anti-clockwise order looking from the outsider of the solid
39 // where it belongs. Its constructor
40 //
41 // G4QuadrangularFacet (const G4ThreeVector Pt0, const G4ThreeVector vt1,
42 // const G4ThreeVector vt2, const G4ThreeVector vt3,
43 // G4FacetVertexType);
44 //
45 // takes 5 parameters to define the four fVertices:
46 // 1) G4FacetvertexType = "ABSOLUTE": in this case Pt0, vt1, vt2 and vt3
47 // are the four fVertices required in anti-clockwise order when looking
48 // from the outsider.
49 // 2) G4FacetvertexType = "RELATIVE": in this case the first vertex is Pt0,
50 // the second vertex is Pt0+vt, the third vertex is Pt0+vt2 and
51 // the fourth vertex is Pt0+vt3, in anti-clockwise order when looking
52 // from the outsider.
