Wings 3D Development Forum

Hi,

I imported a .obj file using the e3d_obj:import("filename") command.
Now I need to access all the vertices from that file. I have attached in the file the record that is created.

Could you please help me figure out how I can access all the values corresponding to 'vs' and store that as a separate list.

As you probably know ... #e3d_file is an intermediate data format. I will find you a snippet that converts into #we{ }

Code:
carveCSGImport(FileName) ->

    case e3d_obj:import( getTempDir() ++ "/" ++ FileName ) of

        {ok,{e3d_file,[],[],[],_}} ->

            { empty, error };

        {ok,E3dFile0} ->

            NameNow = io_lib:format("polyhead~p_~p_~p", tuple_to_list(erlang:now()) ),

            #e3d_file{} = E3dFile0,

            St0 = newSt(),  %% Worried about impact of this new wpa:import on coffin speed. Need test !

            St = wpa:import(E3dFile0, St0),

            Wes = gb_trees:values(St#st.shapes),

            WeNew = wings_we:merge(Wes),

            {ok,WeNew#we{name=NameNow}};

        _OTHER ->

            _OTHER

    end.

So ... wpa:import(E3dFile0, St0)

will get the data into the current wings state #st{}

And then you can just find the last item into that state if you want.

Namrata
