36 // Class description:
37 //
38 // G4ExtrudedSolid is a solid which represents the extrusion of an arbitrary
39 // polygon with fixed outline in the defined Z sections.
40 // The z-sides of the solid are the scaled versions of the same polygon.
41 // The solid is implemented as a specification of G4TessellatedSolid.
42 //
43 // Parameters in the constructor:
44 // const G4String& pName - solid name
45 // std::vector<G4TwoVector> polygon - the vertices of the outlined polygon
46 // defined in clockwise or anti-clockwise order
47 // std::vector<ZSection> - the z-sections defined by
48 // z position, offset and scale
49 // in increasing z-position order
50 //
51 // Parameters in the special constructor (for solid with 2 z-sections:
52 // G4double halfZ - the solid half length in Z
53 // G4TwoVector off1 - offset of the side in -halfZ
54 // G4double scale1 - scale of the side in -halfZ
55 // G4TwoVector off2 - offset of the side in +halfZ
56 // G4double scale2 - scale of the side in -halfZ
