Compute_scalar_product_3

typedef unspecified_type AnalyticWeightTraits_3::Compute_scalar_product_3

A construction object that must provide the function operator:

FT operator()(const Vector_3& v, const Vector_3& w)

that returns the scalar product of the vectors v and w.

Compute_squared_distance_3

typedef unspecified_type AnalyticWeightTraits_3::Compute_squared_distance_3

A construction object that must provide the function operator:

FT operator()(const Point_3& p, const Point_3& q)

that returns the squared Euclidean distance between the points p and q.

Compute_squared_length_3

typedef unspecified_type AnalyticWeightTraits_3::Compute_squared_length_3

A construction object that must provide the function operator:

FT operator()(const Vector_3& v)

that returns the squared length of the vector v.

Construct_centroid_3

typedef unspecified_type AnalyticWeightTraits_3::Construct_centroid_3

A construction object that must provide two function operators:

Point_3 operator()(const Point_3& p, const Point_3& q, const Point_3& r)

that returns the centroid of the points p, q, and r and

Point_3 operator()(const Point_3& p, const Point_3& q, const Point_3& r, const Point_3& s)

that returns the centroid of the points p, q, r and s.

Construct_circumcenter_3

typedef unspecified_type AnalyticWeightTraits_3::Construct_circumcenter_3

A construction object that must provide the function operator:

Point_3 operator()(const Point_3& p, const Point_3& q, const Point_3& r)

that returns the center of the circle passing through the points p, q, and r.

Precondition

The points p, q, and r are not collinear.

Construct_cross_product_vector_3

typedef unspecified_type AnalyticWeightTraits_3::Construct_cross_product_vector_3

A construction object that must provide the function operator:

Vector_3 operator()(const Vector_3& v, const Vector_3& w)

that returns the cross product of the vectors v and w.

Construct_midpoint_3

typedef unspecified_type AnalyticWeightTraits_3::Construct_midpoint_3

A construction object that must provide the function operator:

Point_3 operator()(const Point_3& p, const Point_3& q)

that returns the midpoint between the points p and q.

Construct_vector_3

typedef unspecified_type AnalyticWeightTraits_3::Construct_vector_3

A construction object that must provide the function operator:

Vector_3 operator()(const Point_3& p, const Point_3& q)

that returns the vector through the points p and q.
