My head is full with matrices and models, cameras, views and whatnot. I think I''ve gotten a grasp on it; but doubt still lingers somewhere inside my head Am I understanding the ModelView matrix correctly: The ModelView matrix is used to transform the model or the virtual viewpoint - which in essence is the same, hence the name ModelView. What actually happens is that the coordinate system of the model/object is transformed (instead of moving the object itself) so to create the view I want. Does that seems to be correct? (P.S: I''m sure this has been the subject of many threads here, but the search function as you probably know, is disabled, hence this post - hope it''s ok ). ************************** The best way to accelerate a Win9x machine is at 9.81m/s2
