If you would like to get the 3D object, that belongs to the given pixel, OpenGL gives a simpler way for it with glRenderMode(GL_SELECT); Converting the 3D objects to poligons, seems to be too difficult, and not needed. Take a look after the GL_SELECT mode http://www.google.hu/search?hl=hu&q=glRenderMode%28GL_SELECT%29&meta= Yours sincerely, ______________________________ János Juhász _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
