| 39 | // A G4TwistedTrap is a general twisted trapezoid: The faces perpendicular to the |
---|
| 40 | // z planes are trapezia, and their centres are not necessarily on |
---|
| 41 | // a line parallel to the z axis. |
---|
| 42 | // |
---|
| 43 | // pDz Half-length along the z-axis |
---|
| 44 | // pTheta Polar angle of the line joining the centres of the faces |
---|
| 45 | // at -/+pDz |
---|
| 46 | // pPhi Azimuthal angle of the line joing the centre of the face at |
---|
| 47 | // -pDz to the centre of the face at +pDz |
---|
| 48 | // pDy1 Half-length along y of the face at -pDz |
---|
| 49 | // pDx1 Half-length along x of the side at y=-pDy1 of the face at -pDz |
---|
| 50 | // pDx2 Half-length along x of the side at y=+pDy1 of the face at -pDz |
---|
| 51 | // |
---|
| 52 | // pDy2 Half-length along y of the face at +pDz |
---|
| 53 | // pDx3 Half-length along x of the side at y=-pDy2 of the face at +pDz |

| 55 | // pAlph Angle with respect to the y axis from the centre of the side |
