A general twisted trapezoid.

The faces perpendicular to z are trapezia and their centres are not necessarily on a line parallel to the z axis as the TRAP; additionally, the faces may be twisted so that none of their edges are parallel. It is a TRAP shape, except that it is twisted in the x-y plane as a function of z. The parallel sides perpendicular to the z axis are rotated with respect to the x axis by an angle TWIST, which is one of the parameters. The shape is defined by the eight corners and is assumed to be constructed of straight lines joining points on the boundary of the trapezoidal face at z=-DZ to the corresponding points on the face at z=DZ. Divisions are not allowed. It has 15 parameters:

name: name of the shape
title: shape's title
material: (see TMaterial)
dZ: half-length along the z axis
theta: polar angle of the line joining the centre of the face at -DZ to the centre of the one at +DZ
phi: azimuthal angle of the line joining the centre of the face at -DZ to the centre of the one at +DZ
twist: twist angle of the faces parallel to the x-y plane at z = +/- DZ around an axis parallel to z passing through their centre
h1: half-length along y of the face at -DZ
bl1: half-length along x of the side at -H1 in y of the face at -DZ in z
tl1: half-length along x of the side at +H1 in y of the face at -DZ in z
alpha1: angle with respect to the y axis from the centre of the side at -H1 in y to the centre of the side at +H1 in y of the face at -DZ in z
h2: half-length along y of the face at +DZ
bL2: half-length along x of the side at -H2 in y of the face at +DZ in z
tl2: half-length along x of the side at +H2 in y of the face at +DZ in z
alpha2: angle with respect to the y axis from the centre of the side at -H2 in y to the centre of the side at +H2 in y of the face at +DZ in z
