Thread: 3DS, wavefront obj and milkshape ascii loader for delphi

  1. #21

    Re: 3DS, wavefront obj and milkshape ascii loader for delphi

    Ok i modified that when looking up the class for the file extension lower case is used even if the filename extension is not in lower case.

    Model1.LoadFromFile('models\tulip.3ds');
    Model1.SaveToFile('tulip.txt');
    Model1.Free;
    [/pascal]

    If you need advice on how to write your own descendant from TBaseModel let me know.
    Hi noeska,
    I'm attempting to use your model load as a bridge between my format and the popular ones (.3ds, etc.)...

    Anyhow when I try to use the LoadFromFile() method of the TBaseModel class, my program crashes because the variable FileFormats is Nil at that point

    [pascal]procedure TBaseModel.LoadFromFile(AFilename: string);
    var
    Ext: string;
    GraphicClass: TBaseModelClass;
    begin
    Ext := ExtractFileExt(AFilename);
    Delete(Ext, 1, 1);
    GraphicClass := FileFormats.FindExt(Ext); <----BLOWS UP HERE, FileFormats is Nil!!!
    LoadFromFile(GraphicClass, AFilename);

    //Check if model is loaded

    Calculatesize; //calculate min and max size
    CalculateRenderOrder; //set transparency order...

    //Needs to be called here and not before or else...
    InitSkin;
    end;
    [/pascal]

    My code is basically this:

    [pascal]
    Uses
    Model;

    Var
    Model : TBaseModel;
    Begin
    Model := TBaseModel.Create(Nil);
    Try
    Model.LoadFromFile(<some filename>);
    ....
    Finally
    Model.Free;
    End;
    End;[/pascal]

    Any ideas?
    cheers,
    Paul

    Re: 3DS, wavefront obj and milkshape ascii loader for delphi

    I have it working now

    I added these lines before using the BaseModel.LoadFromFile()

    [pascal] RegisterModelFormat('obj' ,'Wavefront Obj files',TObjModel);
    RegisterModelFormat('3ds' ,'3ds max files',T3dsModel);
    RegisterModelFormat('ms3d','Milkshape 3d files' ,TMsaModel);
    RegisterModelFormat('x' ,'DirectX 3d files' ,TDXModel);
    [/pascal]

    I do have another question...are all the faces in the basemodel triangles only?
    It seems so from the source code and example you posted here...

    cheers,
    Paul

    Re: 3DS, wavefront obj and milkshape ascii loader for delphi

    What delphi version are you using?

    E.g. including glmodel.pas in your uses should be enough to load .obj meshes

    As
    [pascal]
    initialization
    RegisterModelFormat('obj', 'Alias Wavefront Obj Model', TObjModel);

    finalization
    UnRegisterModelClass(TObjModel);
    [/pascal]

    is at the end of glmodel.pas Or is that delphi2005 and above only?

    I'm using D2007 WIn32...

    BTW, should I be using the zip file or the SVN version of the code?

    cheers,

    If you want to use the 'latest features' use svn. I try to keep it in working order. That is not always possible so you better not use the .x reader.

    Could my problem have been because I am using your code inside a DLL?

    Maybe the initialization part isn't called then?

    There is new release for glmodel. Now it is at version 3.5a bringing a new vbo render target.
    You can get i from svn or download it as an zip file from: http://www.noeska.net/downloads/glModel-3.5.0a.zip .
