Hi all,
After studying http://www.racesimcentral.net/
screenshot and the difference is huge. The addition of the following effects in the following order 1) distance blur, the further
the more blur in two layers [far,horizon] 2) noise addition, also in two layers [close (more),far (less)] which gives the tarmac a
much more realistic view and gives a true distance feel to it 3) addition of blur behind the cars, to simulate the heat and dust

These changes where only done after close examination of a dozen real examples.

Compare http://www.racesimcentral.net/://sytex.8m.com/wsc_new5-filter-n-noise.jpg

Any comments?

Impressive!

The motion blur really makes the image come alive.
The asphalt looks a lot better. Much less 'mip-mapped' look.

Hi Leroy,

Very nice work to add realism to this image.  However I have mixed feelings on whether this will work in a sim.  My thinking is that
the eye and brain are processing in similar ways already.  For instance while driving and focusing on the next curve a few hundred feet
ahead, distant vistas or stationary objects passing by quickly on the side of the road are  out of focus since the attention is on the
upcoming curve.  The driver however can choose to look at mountains in the distance (or follow a roadside object) at this time, and
they could be in reasonably good focus before he runs off the road :)
I don't know what the balance would be, or if there is a balance.  I think your levels of blurring are excellent for a still image,
don't know how they would feel while rolling along in a sim.
