|

| 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
|
|---|
| [1315] | 47 | // defined in clockwise or anti-clockwise order
|
|---|
| [831] | 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
