Anyone got any ideas? I have some idea what I had wrote about somewhere. Do not know if it new or can it help. Look. Oh high speed/altitude there is no reason to make tiles polygonal at all. It's so distant/fast to feel much difference. Better to do it way osgEarth engine does. It loads one picture for tile and other picture for altitude by normalmap, as urban shader and normalmap shader do. With shader off it could be simply even surface with Earth texture, with shader on it could be relief. In any case it could be much faster then current multipoligonal tiles. -Victor ------------------------------------------------------------------------------ What Every C/C++ and Fortran developer Should Know!
