Well ok.. I''m looking at these FRACTAL algorithms now since my versions produce only adequate terrains SO I have a 32x32 2d array for my heights right? Ok well for the first line of my grid I calculate like this.. find random midpoint.. break the line into two segments find the midpoints again.. break the line into two segments.. where am I storing these values for the heights? do I take the first row of the array and the compare it to the previous line so I can get accurate looking hills? or what? I''m confused and yes I have gone to www.gameprogrammer.com/fractal.html
