Hi All:

    Google image search is becoming my first source for unexpected
inspiration... as usual, I was searching for something else, when found a
nice aerial pic of the Amazon river.

    Here are some details about this "quick hack":

    + The base terrain is a heighfield, hand-painted over a googlemaps
screen-shot.

    + The river is just a plane, with a bump map also hand-painted in The
Gimp, and a simple orange scattering media for the "muddy water" effect.

    + There are 50,000 POVTrees, using only 4 different meshes. The tree
sizes and distribution are half-guided by a pigment function.

    + The huts were made with Wings3D in about a minute (well, maybe two...)
and the smoke column was borrowed from my office scene (the cigarette smoke).

    + Of course, skylight.inc was used for the lighting.

    + render time was 40 min for the first pass, and just 20 for the final one.

    Regards,

Hmm, out of curiosity, do you have the full stats output?

   Not exactly from that render, but from a later one, and it's the one for
the second pass (load rad data). But now that you mentioned it, I had a look
and I don't see the memory usage reported anywhere...

What fun!  Keep it simple.

I take it the shadows are from clouds?  Nice touch.

You're making me wonder if Avatar is such an achievement after all.

For being a "quick hack", this render is very nicely done! A little more color
variation could help the trees, and the smoke looks a little off, possibly
because it was designed for a smaller-scale scene. For the most part, though, it
looks good!

It must be nice to have inspiration :(

"Quick hack"... you are joking Jaime! Such a scene would take me a couple of 
days at least.

Excellent, as always. Very photographic.

Please, keep us in wonder.

   I'm sorry but a shot inside the forest will reveal there is nothing under
the trees, apart from a pixelated soil texture... it was intended as a sort
of "aerial impressionism". :)

   Yes, I forgot to mention the clouds: it is just a plane with a turbulent
leopard pattern, to cast some shadows.
