61 * Description: Inventor version of the G4Trap Geant Geometry entity
62 *
63 * Author: Joe Boudreau Nov 11 1996
64 *
65 * A G4Trap is a general trapezoid: The faces perpendicular to the z planes
66 * are tapezia, and their centres are not necessarily on a line parallel to
67 * the z axis.
68 *
69 * Note that of the 11 parameters desribed below, only 9 are really
70 * independent - a check for planarity is made in the calculation of the
71 * equation for each plane. If the planes are not parallel, a call to
72 * G4Exception is made.
73 *
74 * Always use Inventor Fields. This allows Inventor to detect a change to
75 * the data field and take the appropriate action; e.g., redraw the scene.
76 *
