InterpolationTraits Concept Reference
Concepts

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

typedef unspecified_type InterpolationTraits::Compute_squared_distance_d

Constructor object for FT.

Provides the operator:

FT operator() (Point_d a, Point_d b) returning the squared distance between a and b.

typedef unspecified_type InterpolationTraits::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.

typedef unspecified_type InterpolationTraits::Construct_vector_d

A constructor object for Vector_d.

Provides :

Vector_d operator() (Point_d a, Point_d b) which produces the vector b - a and

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