Member Typedef Documentation

◆ Aff_transformation_d

defines a matrix type.

Must provide the following member functions :

Aff_transformation tr.inverse (), which gives the inverse transformation, and

Aff_transformation tr.transform(Vector v), which returns the multiplication of tr with v.

◆ Compute_squared_distance_d

Constructor object for FT.

Provides the operator:

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

◆ Construct_null_matrix_d

Constructor object for Aff_transformation_d.

Provides :

Aff_transformation_d operator()(), which introduces an affine transformation whose matrix has only zero entries.

◆ Construct_outer_product_d

Constructor object for Aff_transformation_d.

Provides :

Aff_transformation_d operator()(Vector v), which returns the outer product, i.e. the quadratic matrix v \( ^t\)v.

◆ Construct_point_d

A constructor object for Point_d.

Provides :

Point_d operator() (Point_d p), which simply returns p

Point_d operator() (Weighted_point_d wp), which returns the bare point contained in wp.

◆ 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_scaling_matrix_d

Constructor object for Aff_transformation_d.

Provides :

Aff_transformation_d operator()(FT scale), which introduces a scaling by a scale factor scale.

◆ Construct_sum_matrix_d

Constructor object for Aff_transformation_d.

Provides :

Aff_transformation_d operator()(Aff_transformation_d tr1, Aff_transformation_d tr2), which returns the sum of the two matrices representing tr1 and tr2.

◆ 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.
