GTRA is 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
