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

Types

typedef std::input_iterator_tag iterator_category;
typedef Point_2 value_type;
typedef std::ptrdiff_t difference_type;
typedef const Point_2* pointer;
typedef Point_2 reference;

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.  for all x: |x| range() and for all 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.
