Hi Sebastien,

 

         I tried to zoom into where I am facing problems at, this is my simple code.

 

 

typedef CGAL::Exact_predicates_inexact_constructions_kernel Kernel;

typedef CGAL::Polyhedron_3<Kernel, CGAL::Polyhedron_items_3> Poly_3;

 

template<class k, class e>

class Poly_Extend : public CGAL::Polyhedron_3<k, e>

{};

 

int main(int argc, char* argv[])

{

 

           Poly_3 p3;

           Poly_Extend<Kernel, CGAL::Polyhedron_items_3> p3e;

          

           std::ofstream outputfile("1.stl");

           CGAL::IO::write_STL(outputfile, p3);  // this works

           CGAL::IO::write_STL(outputfile, p3e); // this came up with a lot of compilation errors.

 

}

 

         In this example, p3 works while p3e just cannot be compiled. Do you have any ideas where are the errors?

         Thanks a lot for your help.

 

Regards

Calvin

Subject: Re: [cgal-discuss] How to use CGAL::IO::write_STL using a polyhedron class

 

In your example you use operator<< not write_OFF.

Something like that should work:

std::ofstream outputfile(“poly.stl”);
CGAL::IO::write_STL(outputfile, polyhedron_class);

Sebastien.
