I''m using fog in GL_LINEAR mode over a terrain map: everything works fine, but in direction of the 4 terrain corners, some terrain is behind the fog, because fog is rendered always at the same distance from the origin. There is a workaround to this ? Did i explain it right ? :-) glHorizon_Project

Yeah, use Vertex fog instead of Linear fog. Sorry I dont have much details on this.. I think I actually read about this on Microsofts Dev Network website.

there is an extension (for nvidia cards) see my site nv_fog_range

zedzeek, i tried your tutorials but does the extension work with GL_LINEAR mode ? or is meant to work only n GL_EXP and GL_EXP2 ?

yes i use it with GL_LINEAR

ok, but then nothing changes using or not the extension : fog is always rendered linearly. Of course my card is a geforce ...

theres also a better example with the nvidia effects brouwser (with rotating cubes) try that
