28 // Class description:
29 //
30 // A G4TwistedTrap is a general twisted trapezoid: The faces perpendicular to the
31 // z planes are trapezia, and their centres are not necessarily on
32 // a line parallel to the z axis.
33 //
34 // pDz Half-length along the z-axis
35 // pTheta Polar angle of the line joining the centres of the faces
36 // at -/+pDz
37 // pPhi Azimuthal angle of the line joing the centre of the face at
38 // -pDz to the centre of the face at +pDz
39 // pDy1 Half-length along y of the face at -pDz
40 // pDx1 Half-length along x of the side at y=-pDy1 of the face at -pDz
41 // pDx2 Half-length along x of the side at y=+pDy1 of the face at -pDz
42 //
43 // pDy2 Half-length along y of the face at +pDz
44 // pDx3 Half-length along x of the side at y=-pDy2 of the face at +pDz
45 // pDx4 Half-length along x of the side at y=+pDy2 of the face at +pDz
46 // pAlph Angle with respect to the y axis from the centre of the side
47 //
48 //
49 // A special regular case of a trapezoid with equal endcaps is available,
50 // with polar,azimuthal and tilt angles set to zero.
