* Author: Joe Boudreau Nov 11 1996
|
|
*
|
|
* A G4Trap is a general trapezoid: The faces perpendicular to the z planes
|
|
* are tapezia, and their centres are not necessarily on a line parallel to
|
|
* the z axis.
|
|
*
|
|
* Note that of the 11 parameters desribed below, only 9 are really
|
|
* independent - a check for planarity is made in the calculation of the
|
|
* equation for each plane. If the planes are not parallel, a call to
|
|
* G4Exception is made.
|
|
*
|
|
* Always use Inventor Fields. This allows Inventor to detect a change to
|
|
* the data field and take the appropriate action; e.g., redraw the scene.
