Hi there,

Unless I am mistaken, I found a couple of errors in the basic tutorial (http://www.boost.org/doc/libs/1_54_0/libs/polygon/doc/voronoi_basic_tutorial.htm).

Firstly, 'point_traits' is used for the segment type instead of 'segment_traits'. Secondly, 'p1()' and 'p0()' should be simply 'p0' and 'p1'. So this code:

template <>

struct point_traits<Segment> {

  typedef int coordinate_type;

  typedef Point point_type;

    

  static inline coordinate_type get(const Segment& segment, direction_1d dir) {

    return dir.to_int() ? segment.p1() : segment.p0();

  }

};

should be:

template <>

struct segment_traits<Segment> {

  typedef int coordinate_type;

  typedef Point point_type;

    

  static inline coordinate_type get(const Segment& segment, direction_1d dir) {

    return dir.to_int() ? segment.p1 : segment.p0;

  }

};

Apologies if this has already been covered in another post.
