So, latest installment. After the macros for dropping snow onto objects were
working, I tweaked a few hours (parsing times can get high at times, and
small tweaks can have great impact, and thus, you quickly add up to long
hours...) and went on with the image. A selection of four more trees were
generated with Arbaro and are used with a randomization process to create
the forest, which actually consists of roughly 3200 trees.
Some cleaning up of the sources is in order soon, as I've had to move quite
some things around for several lightgroups. The main tree's trunk casts an
arealight-shadow, but doesn't receive arealights itself, the foreground
casts and receives arealights, the background only point-lights... I'm
pondering what to place above (image-wise speaking, not in 3D) the cat. I've
been experimenting with a small macro to create some random houses and
create a little town, then again, I'd also find it fitting to somehow
encircle the cat with a space of white, to further point out that it is
alone and waiting for it's friend, the bird, to return (which is "back in
spring", hence the small note on the tree).
The sky will of course get some clouds in due time.
Suggestions, comments and questions welcome,
regards,
Tim

i dont think you need anything in the gap, seems to emphasize the
emptiness already
couple of nit picks
do you really get snow that deep on branches ( two stand out )?
sorry, i'm in the uk, odds for xmas snow are rumoured to to be
significantly lower this year !
maybe snow on 'Back in Spring' board ??
snow at base of tree, applicable to all trees in forest or just say 2/3
in from edge ?
trees on the leeward side of forest would logically get less
slightly more bark effect on main tree ?
did you repeat the same tree throughout ? maybe some variation in height
is needed at random
but as usual for you - WOW

That's what I thought. The gap is a little too large, so I think I'll pull
the forest closer unless I find something suitable for the expanse.

It is a little overdone, true. I want to tone it down somewhat, problem is,
reference pics I found so far have that much snow on them, the branches are
all drooping under the weight... Additionally, the amount of snow makes it
easier to see how much there really is, and to get a sense of when it's too
much.
> maybe snow on 'Back in Spring' board ??
That should actually be paper, nailed to the tree, but I'm not yet sure if
that's final.

Yup, that's on my to-do list. The forest was just a rough first
implementation to spread it, the snow was added as an afterthought to every
tree within a 250 unit range.
> slightly more bark effect on main tree ?
I'll try, though I like this one. Too much makes it obvious that it's just a
normal map, so it has to be carefully checked.

Nope, four new different trees for the forest, with random height/size and
position. Maybe I need to enlargen the randomness in height a little.

Eh, thanks for the praise... :-)

How about the moon?
And nice cat/snow/tree, etc!

Great idea, excellent execution but ....
Please look at the colour of tree trunks!
Sorry to bug you with this but it's one of the few things that really annoy
me.

Is it because tree trunks tend to be generally more gray/green than my
wooden brown? I'll test it, but sometimes, a little artistic license is
required...

Tim

I didn't mean the sky, but the landscape, but thanks for the suggestions
anyway. The sky will get some media clouds, I'll have to see if a moon fits.

Thank you!

le message de news:41c5c477@news.povray.org...
This is becoming very nice!!
Just a suggestion: usually, along the border of a wood, trees tend to be
smaller and have branches starting lower than inside the wood because they
don't have to seek light.
Well another suggestion: two or three fences across that wide field
range....
regards
Marc

I'm floored every time you come out with a new image, time. Very
impressed...and inspired too.
One comment, one suggestion and two questions. First the comment, the
face on the cat looks a little strange. Maybe it doesn't at a higher
resolution, I don't know. It's just a little difficult to tell where the
facial features are. It almost looks like the cat's head is tilted to
its left about 45 degrees, but then it also looks like it's pointing its
nose at the sign and smiling. Is this just an illusion at the smaller
size or am I right somehow? :)
Now for the questions. I was taking the garbage out this morning and had
POV and snow on my mind (I promised myself I wasn't going to open up
POV-Ray for about a month, but so far I've broken my promise twice and
it's only half past nine.). I was trying to figure out what made the
difference between real snow and raytraced snow - somehow the fake stuff
always looked, well, fake...yours has excellent distribution, the right
"blobbiness" - yes, it looks that way in real life, I checked - but it's
missing that granulated powdery look. The snow at the base of the tree
has it somewhat, but that's all.
I suppose this could be accomplished with a bump map or some averaged
normals or something, but I was trying to think of a better way to do
it. There seems to be a general sentiment running that bump-mapping is
cheating somehow, and I don't like using normals to simulate actual
shapes (personal preference, probably completely unfounded). So I
wondered...would it be possible to use Surcoat to do the general snow
layer with a good blob factor, then to do it again on top of that and
shrink the blobs to a really tiny size so that they don't join at all,
but rather look like little crystals sitting on top of the snow layer?
Kind of like powdered sugar, in a way.
Second question: how does Surcoat handle the snow layers? Does it call
them all blobs as a union or a merge or is it handled after the scene is
created? I'm wondering whether it's possible to do extra
texturing/finishing/interiors/normals on the snow particles without
having to internally modify Surcoat.
Lastly, the suggestion...it seems likt there's a high "blue factor" in
your snow. With such strong shadows I think it would be a tad more
realistic if it were more blindingly white. Maybe it's that "artistic
license" again...just a thought.
Overall incredible work. You're in my HOF book now. :)
