| 51 | // The G4TriangularFacet class is used for the contruction of |
---|
| 52 | // G4TessellatedSolid. |
---|
| 53 | // It is defined by three vertices, which shall be supplied in anti-clockwise |
---|
| 54 | // order looking from the outsider of the solid where it belongs. |
---|
| 55 | // Its constructor: |
---|
| 56 | // |
---|
| 57 | // G4TriangularFacet (const G4ThreeVector Pt0, const G4ThreeVector vt1, |
---|
| 58 | // const G4ThreeVector vt2, G4FacetVertexType); |
---|
| 59 | // |
---|
| 60 | // takes 4 parameters to define the three vertices: |
---|
| 61 | // 1) G4FacetvertexType = "ABSOLUTE": in this case Pt0, vt1 and vt2 are |
---|
| 62 | // the 3 vertices in anti-clockwise order looking from the outsider. |
---|
| 63 | // 2) G4FacetvertexType = "RELATIVE": in this case the first vertex is Pt0, |
---|
| 64 | // the second vertex is Pt0+vt1 and the third vertex is Pt0+vt2, all |
---|
| 65 | // in anti-clockwise order when looking from the outsider. |
