Awhile back,  I asked everyone here if they had accomplished "rolling"
ground fog.
(the kind you see in the jungle in the old world war 2 movies)
I am assuming this would HAVE to be accomplished using media effects.
I have tried myself to duplicate this effect,  but with sorry results.
So,  does anyone know how this "effect" could be accomplished ?


                                         Thanks,

                                          Johnny

I've done this using a particle system and media (this was in MAX, but the
same should apply to POV-Ray).  The way I did it was to create a particle
emitter that released only a few invisible particles every frame.  Then I
binded a particle based media system to it and set the fractal turbulence
very low.  Then all that was necessary was to animate it.  (the system for
the particle media I used was called FreePyro, a free version of
PyroCluster).

Unfortunately I've lost the original file :(  Otherwise I would have posted
it here for you.

Maybe you could use that particle system that was talked about here a while
ago... and use the particle positions for spheres of media (this is
essentially what FreePyro does)...

I have an irrelevant question.  How does a 16 year old afford Max?  I
can't even afford the student version.

It was actually a present to me :)

My Mum and Dad got really extravagant once and said that I could have
whatever I wanted as a present...  he he he, what can I say, I took
advantage of the situation :)  he he he

        Still fog... I used the word "rolling" because I didn't know how
else to describe it.

Oh, well mine was animated... you can do it anyway... it's just an
alteration of the still... (particle rotation and spliting, media phasing...
that kind of stuff)

  Please show me an example. I would be interested to see how you would
solve this particulr modelling task in Pov-Ray. To me it sounds like a
2 week project but you seem to have it all figured out and I would love
to learn by your experienced insight on the subject.
