Hola buenas compis, tengo un problemilla con los vbo de opengl, actualmente uso display list, ya que son super cómodos, y el paso a vbo me está matando ya que no consigo que pinte absolutamente nada, tampoco es posición de cámara (o eso creo), os paso pego la clase que funciona bien con display list, y el intento de paso a vbo a ver si podéis darme alguna pista, por mas que leo no consigo que ande xD
