The point returned is the orthogonal projection of the 3Dspace origin in the plane.

frame).

public void revertSelf()
Replace the instance by a similar plane with opposite orientation.
The new plane frame is chosen in such a way that a 3D point that had
(x, y)
inplane coordinates and z
offset with
respect to the plane and is unaffected by the change will have
(y, x)
inplane coordinates and z
offset with
respect to the new plane. This means that the u
and v
vectors returned by the getU()
and getV()
methods are exchanged,
and the w
vector returned by the getNormal()
method is
reversed.

This method should be called only for parallel planes otherwise the result is not meaningful.
The offset is 0 if both planes are the same, it is positive if the plane is on the plus side of the instance and negative if it is on the minus side, according to its natural orientation.
