Display lists were removed, because with opengl 3+ all vertex, texture and lighting data are stored on the graphics card, in what is called retained mode rendering (the data is retained, allowing you to send a single command to the card to draw a mesh, rather than sending vertex data to the card every frame). The problem is, this takes about 7 seconds!! It is horribly slow. For a good perspective and look at the scene, use a projection matrix (frustum) with a smaller field of view: glFrustum (-1, 1, -1, 1, 1, 12); Alternatively you can define the frustum by gluPerspective and set the field of view angle in degrees: gluPerspective (90, 1, 1, 12); The view matrix defines the position and viewing direction of.
