Smoke columns

POV-Ray, 2001

This trick extracted from the txt on the great strike.jpg, from Glenn McCarter & N.B., winner of the FIRST ENCOUNTER IRTC round.

It consists on using several copies of a main smoke column constructed out of transparent spheres containing turbulent media, varying slightly the parameters for each copy, and also rotating the copies around the vertical. It's not easy to setup, mainly due to speed reasons, but gives excellent results.
