Dear all:

I could not find a tutorial on defining our own geometric class and use that with CGAL.
Suppose that I would like to define my own class

#include <CGAL/Cartesian.h>
#include <CGAL/Point_2.h>
#include <CGAL/Triangle_2.h>
typedef CGAL::Cartesian<double>     K;
typedef CGAL::Point_2<K>       Point_2;

class MyPoint{
    Point_2      point;
    CGAL::Color c;
    bool deleted;
   
}

What should I do so that I could use MyPoint objects with CGAL functions? Should I derive my own class from the CGAL Point_2 ?

For example:
MyPoint mp1 (x, y, ....), mp2(x1, y1, ...), mp3(x2, y2, ...);
and I would like to use these object with some CGAL functions like

CGAL::orientation (mp1, mp2, mp2), find convex hull, find K nearest neighbor, mke triangle from these point by using CGAL::Triangle, etc...

Thanks so much for your help in advance.

Best regards,

Sophea
