Hello Ashwin

Or, in other words, it returns a tranformation of
projection (onto the xoy plane).

Thanks for your explanation.

B/Rgds
Max

It seems to be an internal function used by Plane_3::to_2d() and
Plane_3::to_3d(). Deriving from the documentation for to_2d(), I would say
this function "returns the affine transformation which maps the plane_3
onto the xy-plane, with the z-coordinate removed."
