Detailed Description

: The documentation from Geant says: A G4Trap is a general trapezoid: The faces perpendicular to the z planes are tapezia, and their centres are not necessarily on a line parallel to the z axis.

Note that of the 11 parameters desribed below, only 9 are really independent - a check for planarity is made in the calculation of the equation for each plane. If the planes are not parallel, a call to G4Exception is made.

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 pAlp1 Angle with respect to the y axis from the centre of the side at y=-pDy1 to the centre 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 pAlp2 Angle with respect to the y axis from the centre of the side at y=-pDy2 to the centre at y=+pDy2 of the face at +pDz
