I would like to use the feedback mechanism of opengl which should send you the list of drawing orders performed by the opengl engine. This is interesting, for instance, for producing a postscript output. does anyone know whether this is implemented in lablgl, and how to use it ? I can see with ocamlbrowser that GlMisc.render_mode `feedback;; does exist. So I thought that was it ! Unfortunately I don't see the command GlMisc.feedback_buffer ();; (or something like this) which, according to the opengl doc, is necessary to define where the feedback orders are queued.
