38 | // |
---|
39 | // G4ExtrudedSolid is a solid which represents the extrusion of an arbitrary |
---|
40 | // polygon with fixed outline in the defined Z sections. |
---|
41 | // The z-sides of the solid are the scaled versions of the same polygon. |
---|
42 | // The solid is implemented as a specification of G4TessellatedSolid. |
---|
43 | // |
---|
44 | // Parameters in the constructor: |
---|
45 | // const G4String& pName - solid name |
---|
46 | // std::vector<G4TwoVector> polygon - the vertices of the outlined polygon |
---|
47 | // defined in clockwise or anti-clockwise order |
---|
48 | // std::vector<ZSection> - the z-sections defined by |
---|
49 | // z position, offset and scale |
---|
50 | // in increasing z-position order |
---|
51 | // |
---|
52 | // Parameters in the special constructor (for solid with 2 z-sections: |
---|
53 | // G4double hz - the solid half length in Z |
---|
54 | // G4TwoVector off1 - offset of the side in -hz |
---|
55 | // G4double scale1 - scale of the side in -hz |
---|
56 | // G4TwoVector off2 - offset of the side in +hz |
---|
57 | // G4double scale2 - scale of the side in -hz |
