Detailed Description

Trapezoid class used for CASTOR volumes.

Required parameters for an ideal trapezoid:

• dxl, dxh, dh, dz, z-face tilt-angle, dR dxl is the HALFlength of the side at smaller y dxh is the HALFlength of the side at larger y dxl and dxh are both either positive or negative; positive means a "right-handed" trapezoid cross section negative means a "left-handed" trapezoid cross section dh is the HALFheight of the actual side, not its projection dz is the HALFlength in z of each long side an is the angle of tilt in the z direction dR is the length of the line in the xy plane from the origin to the perpendicular intersection with the extended edge at the lower-y side of the trapezoid
• locaton x, y and z of faceCenter

Total: 6+3 parameters
