typedef unspecified_type | Compute_area_2 |
| | A model of this concept must provide an FT operator(const Point_2 &p, const Point_2 &q, const Point_2 &r) that returns the signed area of the triangle defined by the points p, q, and r.
|
| |
|
typedef unspecified_type | Compute_squared_distance_2 |
| | A model of this concept must provide an FT operator(const Point_2 &p, const Point_2 &q) that returns the squared Euclidean distance between the points p and q.
|
| |
|
typedef unspecified_type | Compute_squared_length_2 |
| | A model of this concept must provide an FT operator(const Vector_2 &p) that returns the squared length of the vector p.
|
| |
|
typedef unspecified_type | Compute_scalar_product_2 |
| | A model of this concept must provide an FT operator(const Vector_2 &p, const Vector_2 &q) that returns the scalar product between the vectors p and q.
|
| |
|
|
typedef unspecified_type | Equal_2 |
| | A model of this concept must provide a bool operator(const Point_2 &p, const Point_2 &q) that returns true if p = q and false otherwise.
|
| |
|
typedef unspecified_type | Collinear_2 |
| | A model of this concept must provide a bool operator(const Point_2 &p, const Point_2 &q, const Point_2 &r) that returns true if the points p, q, and r are collinear and false otherwise.
|
| |
|
typedef unspecified_type | Collinear_are_ordered_along_line_2 |
| | A model of this concept must provide a bool operator(const Point_2 &p, const Point_2 &q, const Point_2 &r) that returns true if the point q lies between the points p and r and all three points are collinear.
