i'm wondering how would you create a marco that where you could set the
radii of the funnel at the top, then the radii of the bottom part, then the
marco would make a funnel cloud like a torando, but have it curveing this
way and kind of swirling around. and also look like it is an torando?

I have one, sort of. Uses MegaPov sphere_sweep and media.
It's very imperfect and not flexible to use, meaning putting it into any new
scene would require adjustments aplenty from the user.
And of course it's the media that makes it the most difficult. Whole thing
is far from being finished. I was working with it a year ago and quit.
Still interested?

I tried animating one once in POV-Ray v2.2. Was pretty good for 2.2 (had it
ripping out fence posts and trees) but pitiful by today's standards. Maybe
someday I will revisit the idea with ISOs but not today :)

hehe the first few time i use the Torando probably would be more of an
still picture, later on i might attept to animate it but that's very doubful
but i'm still interested, i'm no expert on povray or megapov just btw.

Hope you already have MegaPov, if you do it should be easy just to get a
render of a tornado-like object (minus any clouds). It's no trouble to use
MegaPov anymore now that it works with the POV-Ray CodeMax Editor DLL's as
is anyway.
There are few true "experts" of POV-Ray I believe.
The macro is in the zip file at povray.binaries.scene-files, message subject
is Tornado macro WIP (not "Torando) :-)

BTW, the spelling is "tornado", not "torando", and "macro", not "marco".
I normally wouldn't say anything, but your misspellings seem to be
persistent, not just typos.
About your question, a bunch of media-filled spheres following a spline
might work. MegaPOV will make using media a lot easier, but isn't
absolutely necessary.
Do you want a still image or animation?

My news reader checks my spelling when I send messages. It's a pain
when I paste code into my messages, but I think it's worth the extra
effort.

IMHO it is forgivable to misspell in the body, but misspelling the subject line
is a pain, since searches later on will suffer. "Hmm, wasn't there a recent post
with 'tornado' in the subject - nope..."

My searches give equal weight to the body text, and the total relevance of
a particular post is proportional to how many times the search terms appeared.
So a search for "tornado" would turn up this post before any of the other
posts on the subject, even without fixing the spelling in the subject line.

But searches through only the subject are a lot faster than searches that
look through the bodies as well.

That's highly platform- and archive-format-dependent:
[ron@fwi news]$ date;search -iindex/povray.off-topic qwyjibo;date
Wed Jun 13 15:37:53 EST 2001
# results: 0
Wed Jun 13 15:37:54 EST 2001
[ron@fwi news]$ ls povray/off-topic | wc -l
26515
What this says is that I searched my entire archive of off-topic (26515
articles) in a second or so. That includes subjects, authors, bodies,
and everything else. Surprisingly, nobody has mentioned the word
'qwyjibo' there yet.

Oh, yeah, this is a Pentium 200 with 96M of memory and a Quantum Bigfoot
hard drive. The search would go more quickly on a machine with some
horsepower.

But you are using an index that was generated before, a sequential search
through all files would take much longer even on a faster machine.

I doubt it... having all messages as text files with their names as the subject,
I could perform a pattern search through the whole text and it would give me
back the files that got that pattern but also the lines, having 10000 files of a
few kilo bytes would probably take a few seconds, 1-5 mins max...
time foreach f (`\ls News/*`)
> grep -n "My topic" $f
Although, this would be using the News directory of my system, but I use
netscape and therefore I can't search through files... I'm thinking on using
some kind of fetchmail and fetchnews and use my plain old text programs such as
Emacs!

Of course. As I said, how long it takes to search depends on how you
have it stored.

Emacs supports images, I can't get any of the news readers for it to
work though.
