Not very inspired lately, so I've been playing with height_fields and
isosurfaces.
This scene has one hf, skewed, about 200 isosurface rocks, also skewed,
3 area_lights and one greenish isosurface sitting on the ground.
For the most part the rocks blend in with the bedrock, which I suppose
is a good thing. They use the granite pattern for displacement and were
given the same texture as the hf.
I purposely made the color of the sky a little extreme, attempting to
emulate the great turn of the century painter, Maxfield Parrish.
The greenish isosurface is a cylinder displaced with multiple cos
functions added in a while loop. I think it may be related to the
Fourier Series, though I don't really know much about them.
Render time was just shy of 20 minutes, thanks to the very simple
area_lights (all 2x2).
Any questions, comments etc. are always welcome!

Gotta say that that is some pretty nice texturing there on a very convincing
rock. It's a shame the little rocks don't show up some more and some look
rather strangely placed, but all in all a very nice image.

i do not know if the part of image is (only) well chosen. but it looks very
realistic to me. ain't there an IRTC for realistic pics? that is one for it.

Thanks! Actually, I *almost* used post-processing on it, but that's bit
like cheating. I ended up using an assumed_gamma of 1.3. To add my
signature I used Gimp.

The rocks aren't placed using any kind of special technique. I need to
learn how to #write to text files soon so I can make more complicated
'spot finding' code to place the rocks.

With hf data? Maybe I can compress it into a jpeg... the thing is, the
original code to produce the height_filed has changed!

Actually, I chose the part you see so you wouldn't be able to see the edges of the hf
:)
