| 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.
