I think it would be nice to have media-oriented patterns in order to easily
get some volumetric effect like smoke (does anyone saw the smoke pattern in
Lightflow?) It's so hard to make it work with common pov patterns...
thanks in advance,
JRG.

Well, it's not as straightforward as one would like, but Kevin Wampler (+
some rewrites by Mick Hazelgrove)came up with some nice cloud code using a
blob-density pigment function that might be the kind of thing you are after.

What kind of "media oriented" patterns are you looking for? As far as I
know, the spherical, boxed, cylinderical, and planar patterns were added
specifically for media...
For smoke, have you looked at the blob pattern patch? Maybe that will do
what you want, and it was also designed with media in mind...otherwise,
you are going to need to give more information.

I mean something like this:
density { smoke {type ,start_point, height_of_smoke,turbulence,
something_else}}
And voila' , I get a great looking smoking shape.
I know this can be reached with a bit of work around the blob pattern, but I
think it would be nice to avoid this hard way.
thanks anyway
JRG.

The problem is that this is too specific and narrow, and attempts to do
too much...it is useful for smoke, and only smoke, and would only be
capable of a few specific smoke effects. Also, smoke requires much more
than just a density pattern. It would make a good include file, but not
an internal pattern.
And smoke can already be done with other features, which are much more
versatile.

An easier way would be to use the particle_system patch as a pattern,
but the particle_system pattern isn't functional yet...you could use the
particle_system to position blob pattern components, though.

You can?? Great. I was wondering about that yesterday for mud
splashes on a wall, didn't have time to try it out though.

I'm working on a macro, 2_yr_old_child.inc, which should handle this for you
with very little input. ;)

Just use the get_particle() function to retrieve the needed information,
and use it to position a bunch of blob components.
