Hello everybody,
 
I have to import a surface triangulation into my code and I was wondering what's the best way of doing that.
Basically, I've got the file in this format:
 
x1 y1 z1            // Begin coordinates of points
.. .. ..
xn yn zn            // End coordinates of point
1 2 3                // Point connectivity, describing the triangles of the traigulation
2 5 6
.. .. ..
5 1 n
 
What do I have to do? Create a triangulation T and then simply outputing the content of the file to T?
 
in_stream >> T
 
?
 
I've read the output of out_stream << Triangulation and it seem more or less the same.The only difference is that there are four vertices in the connectivity part, since it's using tethraedrons. Can I use simple triangles in 3D?
 
Thanks
 
Angelo Tardugno
