|
Function object type that provides
Plane_3 operator()(Point_3 p, Point_3 q, Point_3 r), which constructs
and returns a plane passing through p, q, and r and oriented
in a positive sense when seen from the positive side of the plane.
| |
|
| |
|
Function object type that provides
Segment_3 operator()(Point_3 p, Point_3 q), which constructs and
returns the segment with source p and target q.
| |
|
| |
|
Function object type that provides
Triangle_3 operator()(Point_3 p, Point_3 q, Point_3 r), which
constructs and returns the triangle with vertices p, q, and
r
| |
|
| |
|
Function object type that provides
Vector_3 operator()(Point_3 p, Point_3 q), which constructs and
returns the vector q-p
| |
|
| |
|
Predicate object type that provides
bool operator()(Point_3 p, Point_3 q), which determines
if points p and q are equal or not
| |
|
| |
|
Predicate object type that provides
bool operator()(Point_3 p, Point_3 q, Point_3 r), which determines
if points p, q and r are collinear or not
| |
|
| |
|
Predicate object type that provides
bool operator()(Point_3 p, Point_3 q, Point_3 r, Point_3 s), which
determines if points p, q, r, and s are coplanar
or not
| |
|
| |
|
Predicate object type that provides
bool operator()(Plane_3 h, Point_3 q), which determines of the point
q is on the positive side of the halfspace h
| |
|
| |
|
Predicate object type that provides
a constructor taking a single Point_3 object and
bool operator()(Point_3 q, Point_3 r), which returns true iff the
distance from q to p is smaller than the distance from
r to p, where p is the point passed to the object
at construction.
| |
|
| |
|
Predicate object type that
provides bool operator()(Plane_3 p, Point_3 q, Point_3 r), which
returns true iff the signed distance from q to p is smaller
than the signed distance from r to p
| |
Only a copy constructor is required.

For each of the above function and predicate 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:
