I have often wondered how difficult it would be to add something like 
this to the height_field object...have it automatically stitch together 
bicubic patches and remove redundant areas. This would render a little 
faster, be much more memory efficient, and easier to use...but I have no 
idea how easy it would be to code, or where to start coding. It would 
certainly be better than ordinary "smooth" height_fields, though...
