// Class description:
|
|
//
|
|
// A G4TwistedTrap is a general twisted trapezoid: The faces perpendicular to the
|
|
// z planes are trapezia, and their centres are not necessarily on
|
|
// a line parallel to the z axis.
|
|
//
|
|
// pDz Half-length along the z-axis
|
|
// pTheta Polar angle of the line joining the centres of the faces
|
|
// at -/+pDz
|
|
// pPhi Azimuthal angle of the line joing the centre of the face at
|
|
// -pDz to the centre of the face at +pDz
|
|
// pDy1 Half-length along y of the face at -pDz
|
|
// pDx1 Half-length along x of the side at y=-pDy1 of the face at -pDz
|
|
// pDx2 Half-length along x of the side at y=+pDy1 of the face at -pDz
|
|
//
|
|
// pDy2 Half-length along y of the face at +pDz
|
|
// pDx3 Half-length along x of the side at y=-pDy2 of the face at +pDz
|
|
// pDx4 Half-length along x of the side at y=+pDy2 of the face at +pDz
|
|
// pAlph Angle with respect to the y axis from the centre of the side
|
|
//
|
|
//
|
|
// A special regular case of a trapezoid with equal endcaps is available,
|
|
// with polar,azimuthal and tilt angles set to zero.
