Can anyone give me a quick pointer or two on creating "realistic" tornados?
TIA, Greg.

i think bob hughes was working on one a while ago.  he was only lukewarm
about his results and i think he may have been the only person to ever
try.  check his pics and animations in the appropriate ng's and his web
site.

Yep, media used of course so it's not easy to adjust.
There's a "tornado.pov for dust-devils, etc." posted to
povray.text.scene-files on April 18th of this year.
Maybe that will help.  Not easy to describe.

When I was a releatively new user to the program I tried to make an
animated tornado but my results were less than spetacular. I did
manage to get it to suck up a row of trees and tear down a wire
fence line as it passed by :)
 I may revisit this idea some day but I really have nothing to offer
someone else starting out that would prove useful.

I cheated by using a bozo pattern with phase applied and kept the
distance to the camera far enough away that you couldn't see any
details.

Well, oddly enough, the media I tried to do it with kept looking like it was
fitted to a surface instead of being filled into the 3D shape.
I just happened to think, I used 'sphere_sweep' in MegaPov after that other
pov script I made, it does a good elephants trunk kind of funnel.  Not sure if
I also posted that there or not.  If you need to ask anything more just speak
up Greg.

Thanks for the advice. I checked out the tornado.pov and have some ideas. If
I come up with anything I'll post. Greg.
