WIP 4 IRTC
Now with traced trees - 20,000 of them. Took me a while to find a way of making
trees that didn't eat up memory. Managed it by combining meshes and cylinders
and adapting quality depending on distance.
There were meant to be stars as well, but I made a boo-boo...

I like it a lot. I if render time is reasonably then I have idea: animate it
with camera moving along footprints. After each set of frames apear new
footprint but no person at all. I mean invisible Yeti.

very nice scene!
I think the trees are standing a little bit too loose.
Lighting is quite bright for a night... even in case of full moon.
What about adding footprints of animals to the snow? Most likely Rabbits,
Birds and Squirrels?
How did you build the mountains in the background so that the snow doesn't
cover the tip independently of the mountain's height?

I did the same with my fern. Otherwise 106000 objects blew up PC's memory...
now reduced to few thousands.
Cool picture anyway!
BTW: what is current the theme of the IRTC?

Cool idea. Only there aren't Yeti in Narnia IIRC. I do remember invisible
footprints, but they weren't in snow. Maybe the witch made herself invisible?

yikes,
looks like a lot of the country around here, especialy the places I go
snomachining
(except the mountains are further away here) In other words: Realistic!
It never ceases to amaze me what you guys can acomplish.
Gary
P.s. Would you be willing to share some code for the trees and the snow? :-)

Hmm, I've been thinking of animating (just out of curiousity - I wanna see
what's over the nearest hill). Render time is pretty reasonable, so I'll see
what I can come up with.

Hey, well remembered! They were in Voyage of the Dawn Treader - one of the
islands had one-legged invisible gnomes. The queen didn't turn herself
invisible, but she did turn herself and her no. 1 dwarf into a rock and a tree
iirc.

Hmm, well I just use a y slope, so I suspect that all the tips are covered - it
just leaves the shearer faces uncovered.

very nice Tom, but shouldn't the snow near the base of the tree be lower
than that in the open? (because the snow collecting on the branches.)

I'm working on it, I'm working on it. ;) - well actually, I was thinking more
that there should be a small indented cone at the base of each tree since, iirc,
you get some melting close to the trunk - I'm not sure how much general indent
there would be, what with drifting and so on.

Hi Tom.
Nice mountains, trees and snow. Very realistic.
Great image. Waiting to see your next version.

This is looking really nice, especially the work on the trees, although I'm
not totally convinced by the mountains.

Although neither the mountains nor the trees are extremely realistic it
looks somehow beautiful, concerning the trees, if you make only about 5-10
different ones each as one mesh and place multiple instances this will
save a lot of memory, even if you don't reduce detail for the more distant
ones. In addition grouping the trees into several unions would can also
speed up the render a lot.

Even a small indent would go along way. I would not worry about being exact.

The short trees look a bit squashed; did you use the same object as for
