This scene makes use of the eval_pigment function to place trees on 2
hight_fields. There are more than 10000 trees and palms.
Strange thing is that it is not possible to render this scene with the
official POV-Ray 3.6 version on my system (3.6 GHz P4 with 2 GB RAM under
Win XP Home with SP2). I allways get memory allocation errors. So I tried
MegaPov 1.1. Bingo!! Parse time reduced by at least a factor 4, no memory
allocation issues. Render time seemed much faster to me too, although this
is hard to judge because the scene crashed with the official version if
rendering all elements. Did anybody else notice similar behaviour?
About the image: The trees were made with POVTree, palms are freebies from
the internet (sorry, I forgot where I downloaded them)textured in POV-Ray,
clouds are made with Gill Tran's MakeCloud and the parrots are Poser
models. The scene rendered in 4.5 hours at 1600x1200 and peak memory used
was about 350 MB only.
Regards and have a nice easter weekend, Christoph

Nice image. I like it very much.
The only thing that looks odd is the the bright red pixel in the middle
of the image. Is it a bird?
Happy easter to all!

Wonderful image! The red is a bird. I wonder how a super
high resolution image would look, this makes me want to
see more of the details. It'd make a great large canvas work.

Great scene, great theme. Where I have been heading myself. Are you
working from a reference?

Gorgeous!!
It could do an excellent picture for an adventure book.
Do you use eval_pigment to choose which specie will be found at this or that
place or do you use it instead of trace()?

Actually both functions are needed. The principle is not new, it has been
discussed here earlier. In this scene I used eval_pigment() and a spotted
pigment to distribute the trees and trace() to find the exact height of the
height_field at a given position.
You could do the same thing with random distribution of the trees but I
think a little structure in the forest looks better.

That was my guess :-)

Very impressive, Christoph! I had not yet had the time to use the
eval_pigment function, but I confess that you have pushed me to it. Like was
said above, it would make an excellent illustration for an adventure
book.... I hope to write one myself, one day...
