Also c...Very very nice... Can use this DOF effects.<br />Also can be used as a nice gameplay feature during the game ;)MarmAmichttps://www.blogger.com/profile/11745509724058056306noreply@blogger.comtag:blogger.com,1999:blog-1096533244660546051.post-22996903249847939202011-01-06T13:07:13.332-08:002011-01-06T13:07:13.332-08:00hi again

I...Have a look at <a href="http://www.3dmark.com/wp-content/uploads/2010/12/3DMark11_Whitepaper.pdf" rel="nofollow">futuremarks 3dmark11 whitepaper</a>.<br /><br />It seems they use a modernized version of the lost planet dx10-method (render sprite for each pixel on screen, low-res) - while streaks/glare etc. is using FFT.<br /><br />I believe the issue with using FFT for DOF is that you have to run it on multiple layers. This can be done (e.g. <a href="http://www.mpi-inf.mpg.de/~slee/pub/" rel="nofollow">http://www.mpi-inf.mpg.de/~slee/pub/</a> ) but isn't as fast.pixelmagerhttps://www.blogger.com/profile/09748636815553857006noreply@blogger.com
