My program generates a fractal terrain(looks pretty cool) but i don''t know how to render the altitudes(to indicate the ''level'' of the terrain). Can i do it with texturing? Do u have other ideas? Choko

Try to make the lower level more darker and the upper lighter. (Use the ''glColor3f''()'' to do this)
Can you explain me the term ''fractal terrain'', I think that means that the terrain is only shown as ''quad fields''.

Have a look at this great article which describes the ROAM algorithm. I think that''s the best way to display a terrain.
