CGAL::Points_on_segment_2<Point_2>

Definition

The class Points_on_segment_2<Point_2> is a generator for points on a segment whose endpoints are specified upon construction. The points are equally spaced

Creation

Points_on_segment_2<Point_2> g ( Point_2 p,
Point_2 q,
std::size_t n,
std::size_t i = 0);

g is an input iterator creating points of type P equally spaced on the segment from p to q. n-i points are placed on the segment defined by p and q. Values of the index parameter i larger than 0 indicate starting points for the sequence further from p. Point p has index value 0 and q has index value n-1.
Requirement: The expressions to_double(p.x()) and to_double(p.y()) must result in the respective double representation of the coordinates of p, and similarly for q.

Operations

double

g.range ()

returns the range in which the point coordinates lie, i.e.

x: |x| range() and

y: |y| range()

Point_2 g.source () returns the source point of the segment.

Point_2 g.target () returns the target point of the segment.
