Member Typedef Documentation

◆ Compute_area_2

Constructor object.

Must provide an operator FT operator()(Point_2 p, Point_2 q, Point_2 r); that computes the signed area of the triangle defined by the points p, q, and r.

◆ Construct_circumcenter_2

Constructor object.

Must provide an operator Point_2 operator()(Point_2 p, Point_2 q, Point_2 r); that constructs the center of the circle passing through the points p, q, and r.

Precondition
p, q, and r are not collinear.
