Wrote some codes in java to simulate the effect as Pov ray's turbulence warp.

I like this but 18 hours render time! What is the resolution of the image?

If the sun is on the horizon should it not be redder?

BTW can your sky sphere map generator, create a green flash?

When the sun is on the horizon it can be yellow, red, or invisible, just depend
on the atmosphere condition.
My program could be rich on the atmosphere condition settings. But still work in
progress.

The video is so perfect!(maybe with the music)

Green flash is due to air refract, my program can turn on air refract, but have
bugs and still not implement for different wavelength.
