I find that Polyhedron_3<Traits> does not consider ther coordinates of the points, so I insert two triangles like this:

 

Point_3 p( 0.0, 0.0, 0.0);

Point_3 q( 1.0, 0.0, 0.0);

Point_3 r( 1.0, 1.0, 0.0);

Point_3 s( 0.0, 1.0, 0.0);

 

s    _ _ _ _  r

|\   \        |

|  \  \       |

|    \  \     |

|      \  \   | 

|_ _ _ \  \ |

p              q

 

Polyhedron P;

P.make_triangle(p, q, s);

P.make_triangle(s,q ,r);

 

but the triangle 'pqs' and 'sqr' do not connect correctly, it has four halfedges along the segment 'sq'. 

 

I want to merge the different edges 'sq' in the two triangles, so the rectangle 'spqr' will be colsed. Is there any way?
