I'm about to go crazy with this code. I load the mesh/model from a 3ds file with a proper loader and I put it to render but nothing appears. Here is the code:

}


Text3D works finely, Text2D also, the primitives as well, my only problem is with the mesh/model.
Please someone give me some help!!

P.S.: My problem is that I can't see the mesh rendered! It's not the API, other program(not written by me) works finely with the very same mesh. It's not the lib. I don't know what is!

Hi

Change the viewing transform or translate and rescale your model so that it is inside this frustum.
