typedef unspecified_type Construct_cross_product_vector_3
 Functor with operator: Vector_3 operator()(const Vector_3& v, const Vector_3& w) const, which constructs the cross product of v and w.
 
typedef unspecified_type Compute_scalar_product_3
 Functor with operator: FT operator()(const Vector_3& v, const Vector_3& w) const, which constructs the scalar product ofvandw`.
 
typedef unspecified_type Compute_squared_distance_3
 Functor with operator: FT operator()(const Point_3& p, const Point_3& q) const which computes the squared distance between p and q.
 

Operations

For each of the above function object types, Func_obj_type, a function must exist with the name func_obj_type_object that creates an instance of the function or predicate object type.

For example:

Construct_vector_3 construct_vector_3_object ()

◆ Point_3

typedef unspecified_type HeatMethodTraits_3::Point_3

The 3D point type.

It must be CopyConstructible and DefaultConstructible, and have a constructor with three parameters of a type constructibe from double.

◆ Vector_3

typedef unspecified_type HeatMethodTraits_3::Vector_3

The 3D vector type.

It must be CopyConstructible and DefaultConstructible, and have a constructor with three parameters of a type constructibe from double.
