8 // Description: Dimensionally, all you need to know about a trapezoid
9 //
10 // Usage:
11 // This class exists because there are many lengths and
12 // angles of interest in a trapezoidal polyhedron,
13 // and it makes more sense to put them in one place.
14 //
15 //
16 // Our naming convention is as follows: lower case abcdh at +Z
17 // upper case ABCDH at -Z
18 // L = full length in Z
19 // a1, a4 = angles at vertices 1,4
20 // hXx = perp distance between X, x
21 // (x15,y15) = coord of v5 wrt v1

46 // Specifying the minimal parameters for a GEANT TRAP
47 // requires 9 numbers, *NOT* 11 as used in GEANT or DDD.
48 //
49 // We choose the following 9:
50 // L/2, a/2, b/2, h/2, a1, A/2, H/2, hAa, x15
51 // In GEANT these correspond to
52 // dz, bl2, tl2, h2, -, bl1, h1, -, -
