   how did they do vision modes in AVP2
  I was wondering how they did the vision modes in aliens vs predator 2. If anyone knows or knows a way to do it please let me know. i use C++/OpenGL. 
  Alien vs. Predator 1 is open source.  Go look in there. ;  They increased the FOV and added a 2D overlay ;  not quite. remember the heat sensitive camera? And the glow around humans in alien vision modes?  ;  "remember"? wtf? AvP will be my fav for ever and ever! ;  guess who I''m working for ;  *Green of envy* ;  thanks, i''ll go take a look at the source. didn''t know it was available ;  That heat vision mode could be done using something like the "depth peeling" or the volume fog stuff known from the NVIDIA website I guess...just my 2 cents,Alex ;  How about a link to that source?
