what first step i must do ?
i guess:
i must find per-fragment depth of back and front fog mesh faces!
per- fragment depth is calculated as vectorlength(camera-fragment.pos) ? right ??
calculations in fragment program!

your topic title must be something like 'shader fog'
'volumetric fog' is misleading making ppl or atleast me to think of the gl extensions for volumetric fog
