Hi Guillaume,

Appical_sheet_3 is only mentioned in the typedef

Here is the code for the function calling point_of_vertex_attributes:

void make_polygon(Appical_sheet_3 &sheet, std::vector<Point> &points) {
  std::size_t n_sides = points.size();
  Dart_handle dh = make_combinatorial_polygon(sheet, n_sides);
  Dart_handle prev = dh;
  Dart_handle next;
  for (std::vector<Point>::iterator it = points.begin(); it != points.end(); ++it){
    next = sheet.beta(prev, 1);
    Vertex_attribute_handle vh = sheet.create_vertex_attribute(*it);
    sheet.set_vertex_attribute(prev, vh);
    //int id = sheet.info<0>(vh);
    std::cout<<"Point: " <<sheet.point_of_vertex_attribute(vh)<<std::endl;
    prev = next;
  };
};

And the error message:

/home/guillaume/Python/tyssue/src/cpp-tyssue/objects.cc: In function  ‘void make_polygon(Appical_sheet_3&,  std::vector<CGAL::Point_3<CGAL::Simple_cartesian<double>  > >&)’:
 /home/guillaume/Python/tyssue/src/cpp-tyssue/objects.cc:50:34: error:  ‘Appical_sheet_3’ has no member named ‘point_of_vertex_attribute’
      std::cout<<"Point: " <<sheet.point_of_vertex_attribute(vh)<<std::endl;
                                   ^

Thx

Guillaume

Hi,

What am I doing wrong?

I define a LineraCellComplex like that:

typedef CGAL::Linear_cell_complex<2,3,Traits,Epithelium_Items>     Appical_sheet_3;

When trying to access one Appical_sheet_3 instance point attributes, I get the following error (also for other documented members of LCC)

‘Appical_sheet_3’ has no member named ‘point_of_vertex_attribute’

Without the code it is difficult to find the problem...

Appical_sheet_3 is a type or an instance ?
Because it is not clear above (this is the name in the typedef, but this is also the name in the error message which is supposed to concern an instance).

Best
Guillaume

Appart from that, I manage to build polygons and call member functions as create_vertex_attribute(*it)

hint: I'm new to C++, so something obvious might elude me…

Best,

Guillaume
