#7 convert to customized datastructure

[nourhan]

hello ,
I'm creating an application witch import .obj files and read it with customized data structure . now I want to convert the read data to gtsSurface to use gts Simplification .
any help or useful links?

GtsSurface* Mesh::TO_gts(GtsSurface* s)
{

 for( auto CMFace : HEF )
 {

     GtsVertex* v1=gts_vertex_new(s->vertex_class,CMFace->edge->cMVertex->vertex.x,CMFace->edge->cMVertex->vertex.y,CMFace->edge->cMVertex->vertex.z);
      GtsVertex* v2=gts_vertex_new(s->vertex_class,CMFace->edge->next->cMVertex->vertex.x,CMFace->edge->next->cMVertex->vertex.y,CMFace->edge->next->cMVertex->vertex.z);
    GtsVertex* v3 = gts_vertex_new(s->vertex_class,CMFace->edge->next->next->cMVertex->vertex.x,CMFace->edge->next->next->cMVertex->vertex.y,CMFace->edge->next->next->cMVertex->vertex.z);
     GtsEdge* e1 = gts_edge_new (s->edge_class,v1, v2);
     GtsEdge* e2 = gts_edge_new (s->edge_class,v1, v3);
     GtsEdge* e3 = gts_edge_new (s->edge_class,v3, v2);

 GtsFace * f = gts_face_new (s->face_class,e1, e2, e3);
 gts_surface_add_face (s, f);
return s;
 }

and this conversion try doesn't work
