Heat Shimmer

This shader is an attempt at simulating the shimmering quality of hot air, (for example, the heat rising off the road on a hazy summer day, or the warm air coming out of a chimney or a vent on a cold winter day.)

Parameters:

Granularity
Frequency
Amplitude

SGI movie (0.3M)

Remarks

The only fading functionality built in at the moment is based on the direction of the surface normal with respect to the viewer, eg. using a model which curves away at its edges.
In the example flipbook, however, only a flat grid is used (the grid is perpendicular to the road and stops about halfway up the skeleton.)
