Hi,

I'd like to visualize a 2D uniform  triangulation using geomview, my definitions are as follow:

typedef CGAL::Cartesian<double> K;

typedef K::Point_2 Point;

typedef K::Segment_2 Segment;

typedef K::Triangle_2 Triangle;

typedef CGAL::Triangulation_2 <K> Triangulation;

And i build my uniform triangulation as follow:

short m_size_u = 49;

short m_size_v = 68;

int u,v,i,j;

Face_handle f,g;

for (u = 0; u<m_size_u; u = u+1)

{

for (v = 0 ;v< m_size_v; v= v+1)

{

i = u+1;

j = v+1;

f = T.create_face(T.insert(Point (u,v)),T.insert(Point (u+1,v)),T.insert(Point (u,v+1)) );

gv<<T.segment(f,0);

gv<<T.segment(f,1);

gv<<T.segment(f,2);

gv<<T.triangle(f);

g = T.create_face(T.insert(Point(i,j)),T.insert(Point(i-1,j)),T.insert(Point(i,j-1)) );

gv<<T.segment(g,0);

gv<<T.segment(g,1);

gv<<T.segment(g,2);

gv<<T.triangle(g);

}

}

The problem is when I launch my application in a terminal (./test_triangulation) Geomview stops visualizing suddenly and the error message is:
write problem in the pipe while sending data to geomview.

Does somebody know why this error (I think that the number of triangles is not big enough) happens and how to avoid it!

Best regards!
