Just thought it's about time to start the winter season, the first
christmas trees are also being grown, so here is some fresh snow...
It's written new from scratch in about 1-2 hours, i wonder if there is
already a good snow macro available, but i don't remember anything.
The construction is quite simple, blob compontents positioned by trace
(47000 in total) so a lot of things are not yet very realistic.

I like this very much!
I can see some imperfections but it's promising to say the least.

There are some regular patterns from the fact that you used a grid to
position the components...maybe a random placement would be better. You
could also use eval_pattern() or eval_pigment() to control the density
of the snow, make it look more uneven on the flat areas.

You cheated, you used shaving foam instead.

The snow looks thicker than it probably should, but it is very very cool. It
needs icicles. Also, it looks like the snow fell straight down, does your
method allow you to defind a wind direction that would place the snow to one
side of everything?

We had a snow that looked exactly like this a couple days ago...all you
need is a damp snow that is constantly drifting straight down, with
little wind and no sun.

Very funny...

Isosurfaces!

I think he just used the trace() function going straight down from the
sky. Slanting the direction you give trace() should give you something
like that effect.

I think foam would probably need a bit less 'heavy' texture.

I don't think completely random would be good, but some 'jitter' could
probably help.

That's a good idea, thanks.

Just changing the direction would not be that good, because the snow
should much depend on tho slope, so you would have to take the normal
vector into account (right now it isn't used). Usually the snow on the
wind side of objects is thinner and less regular.
icicles would be nice, but they would involve pretty much calculation to
be placed properly.
