Kernel::ConstructProjectedXYPoint_2 Concept Reference

Definition

Operations

A model of this concept must provide:

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.

◆ operator()()

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.
