| 67 | * A G4Trap is a general trapezoid: The faces perpendicular to the z planes |
---|
| 68 | * are tapezia, and their centres are not necessarily on a line parallel to |
---|
| 69 | * the z axis. |
---|
| 70 | * |
---|
| 71 | * Note that of the 11 parameters desribed below, only 9 are really |
---|
| 72 | * independent - a check for planarity is made in the calculation of the |
---|
| 73 | * equation for each plane. If the planes are not parallel, a call to |
---|
| 74 | * G4Exception is made. |
---|
| 75 | * |
---|
| 76 | * Always use Inventor Fields. This allows Inventor to detect a change to |
---|
| 77 | * the data field and take the appropriate action; e.g., redraw the scene. |
