Operations  
Kernel::Point_2  operator() (const Kernel::Plane_3 &h, const Kernel::Point_3 &p) 
returns the image point of the projection of p under an affine transformation, which maps h onto the \( xy\)plane, with the \( z\)coordinate removed. More...  
Kernel::Point_2 Kernel::ConstructProjectedXYPoint_2::operator()  (  const Kernel::Plane_3 &  h, 
const Kernel::Point_3 &  p  
) 
returns the image point of the projection of p
under an affine transformation, which maps h
onto the \( xy\)plane, with the \( z\)coordinate removed.
This affine transformation must be the inverse of the affine transformation used in ConstructLiftedPoint_3
