I was wondering if anyone has any thoughts on how to create a desert mirage effect in a game. Something like the effect you see on the runway in the picture at http://www.defenselink.mil/photos/Mar1998/980312-F-7910D-007.html
It's basically a very strong refraction that effectively is creating a reflection of the sky, so I was wondering if one could start with the water shader and either go with the surface reflection method or even crank up the refraction to match how a real mirage works. Modify it so that it was only visible at a long distance and high incident angle between the viewer and the normal surface. Then create a flat thin brush of the "mirage material" over the surface of a large flat area such as a runway or desert floor.
