Surprisingly, I am unable to make wind and gravity work in Rune's
particle system. I read and re-read the doc and I seem to follow the
rules. These are the corresponding lines of code (see also the image in
p.b.i.):
#declare particle_drag = 10;
#declare particle_transfer = 1.0;
#macro particle_gravity (Clock,Point) <0,-1,0> #end
#macro particle_wind (Clock,Point) <10*Clock, 0, 0> #end
So, if Rune, or anybody familiar with the macros can help me, I shall be
most grateful.
Thomas

Hi Thomas,
I see that you have no answers so far. I cannot answer so fast since Rune's
system seems to be far away from the particle system I programmed in java for my
diploma some years ago. My system was only an input for statistical
condiderations and I lost the code due to a headcrash unfortunately. But I will
investigate this issue further (when time allows) and have a solution hopefully.
This is a very interesting program.
Regards,
Michael

I forget to request a thing. I rendered the example scene from Rune with your
settings and yielded an error due to an unknown identifier #IND. Was this your
problem?
This stands for an overflow in a float value (infinity). If POV (or Visual C++
which is used to programm POV, I cannot judge at the moment which of the both
caused that error) gets a value to high to represent in a float it will produce
such an output in a text file. Since Rune's particle system writes its output to
file and included it the next round (round means not frame, he has several
"rounds" during one frame), it reads this representation of infinity and POV
cannot interpret it. The first remedy to your problem seems to be: Don't go for
a hurricane which blows a hole in the entire earth. Try a value lower then 6 for
particle_drag. I yielded this error at a value near 6.25 with Runes smoke-scene.
And to your convenience: I have not found a contradiction to your settings in
the manuals of Rune.
Regards,
Michael

Thanks Michael,
I have abandoned for the time being but will get back to this shortly.
My problem was not an error message but the inability to create a smoke
trail responding to my input, especially wind. I am sure it is due to my
misunderstanding of something essential...

Hi Thomas,
particle system again after a long time. So to answer one of your questions.
#macro particle_gravity (Clock,Point) <0,-1,0> #end
Should be #macro particle_gravity (Clock,Point) <0,-9.81,0> #end
In the metric system and #macro particle_gravity (Clock,Point)
<0,-32,0> #end in our quaint imperial system. If the clock runs from 0
to 1 you will only get 1 seconds worth of animation so you will need to
extend the Final_Clock (+KFn.n) to however long you need.
environment settings yet.

Frankly, I don't know what went wrong because now everything works as
expected and with identical settings. Very strange indeed...

And beat it when it glitches.
It only does it to annoy
Because it knows it itches.
With apologies to Lewis Carroll.

Wow! wow! wow! :-)
There are none better than Lewis Carroll for this.
Twinkle, twinkle, little bit
How I wonder what you did!
Back behind the screen you glitch
Until I - to off - you switch. [ouch! this is really crooked]

Edward Lear and Ogden Nash have a good go, too.

Don't you mean:
Twinkle, twinkle, little bat!
How I wonder what you're at!
Up above the world you fly,
Like an iso-surface in the sky.
You know that you have been Poving too long when...

Definitely needs more keywords ;)
