CGAL 5.4 - 2D and Surface Function Interpolation
InterpolationTraits Concept Reference

Definition

Most interpolation functions are parameterized by a traits class that defines the primitives used in the interpolation algorithms. The concept InterpolationTraits defines this common set of requirements.

Has Models:

CGAL::Interpolation_traits_2<K>

CGAL::Interpolation_gradient_fitting_traits_2<K>

Member Typedef Documentation

◆ Compute_squared_distance_d

Constructor object for FT.

Provides the operator:

FT operator() (Point_d p, Point_d q) returning the squared distance between p and q.

◆ Construct_point_d

A constructor object for Point_d.

Provides :

Point_d operator() (Point_d p) which returns the point itself.

Point_d operator() (Weighted_point_d wp) which extracts the bare point from the weighted point.

◆ Construct_scaled_vector_d

Constructor object for Vector_d.

Provides :

Vector_d operator() (Vector_d v, FT scale) which produces the vector v scaled by a factor scale.

◆ Construct_vector_d

A constructor object for Vector_d.

Provides :

Vector_d operator() (Point_d p, Point_d q) which produces the vector q - p and

Vector_d operator() (Null_vector NULL_VECTOR) which introduces the null vector.
