Javadoc
Copies the inverse of the current Vworld projection transform
for each eye into the specified Transform3D objects. This
transform takes points in clipping coordinates, which are in
the range [-1,1] in X, Y, and Z after
clipping and perspective division, and transforms them into
virtual world coordinates.
In monoscopic mode, the same inverse projection transform will
be copied into both the right and left eye Transform3D objects.
