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?

That's a very dramatic, striking picture! I can't wait to see the finished
product...

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?

Wow. Trees are very very nice.
Don't forget the lamppost.

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.
