| Line_3<Kernel> l ( Point_3<Kernel> p, Point_3<Kernel> q); | |
|
introduces a line l passing through the points p and q.
Line l is directed from p to q.
| |
| Line_3<Kernel> l ( Point_3<Kernel> p, Direction_3<Kernel> d); | |
|
introduces a line l passing through point p with
direction d.
| |
| Line_3<Kernel> l ( Point_3<Kernel> p, Vector_3<Kernel> v); | |
|
introduces a line l passing through point p and
oriented by v.
| |
| Line_3<Kernel> l ( Segment_3<Kernel> s); | |
|
returns the line supporting the segment s,
oriented from source to target.
| |
| Line_3<Kernel> l ( Ray_3<Kernel> r); | |
|
returns the line supporting the ray r, with the
same orientation.
| |
| bool | l.operator== ( h) const | Test for equality: two lines are equal, iff they have a non empty intersection and the same direction. |
| bool | l.operator!= ( h) const | Test for inequality. |
| Point_3<Kernel> | l.projection ( Point_3<Kernel> p) const | |
| returns the orthogonal projection of p on l. | ||
| Point_3<Kernel> | l.point ( int i) const | returns an arbitrary point on l. It holds point(i) = point(j), iff i=j. |
| bool | l.is_degenerate () const | returns true iff line l is degenerated to a point. |
| bool | l.has_on ( Point_3<Kernel> p) const | |
| returns true iff p lies on l. | ||
| Plane_3<Kernel> | l.perpendicular_plane ( Point_3<Kernel> p) const | |
| returns the plane perpendicular to l passing through p. | ||
| Line_3<Kernel> | l.opposite () const | returns the line with opposite direction. |
| Vector_3<Kernel> | l.to_vector () const | returns a vector having the same direction as l. |
| Direction_3<Kernel> | l.direction () const | returns the direction of l. |
| Line_3<Kernel> | l.transform ( Aff_transformation_3<Kernel> t) const | |
| returns the line obtained by applying t on a point on l and the direction of l. | ||
