Has anyone already suggested making a (cross-eyed) stereo-pair?

Women are the canaries of science. When they are underrepresented
it is a strong indication that non-scientific factors play a role
and the concentration of incorruptible scientists is also too low

I think this is possible with an L-System. You need an L-System which is open
and has random rules at least. Then you can introduce a rule which replaces a
stem-segment with the same stem-segment and a new bud with an open parameter.
Within the processing of the open parameters you introduce a second random rule
which find a free place at the rocks e.g. by trace and place the bud there, or
just place a new branch at the existing stem.

This should be possible with the L-System I used for growing plants to light
(http://news.povray.org/povray.binaries.animations/thread/%3Cweb.5105b31b81d10535153a49f10%40news.povray.org%3E/).
The source to that is in the p.b.s-f. But one must spend some more effort into
the modelling of the plants...

Best regards,
Michael

That's an idea. I only have a method for a (wide-eyed?) stereo-pair  
though. Do you have any code, or do you do it with separate renders?

Here are some more renders.

The "grin" in #19 is purely by accident :D

You only need to reverse the positions of each parts. If you have a 
parameter for the eyes separation or parallaxe, just negate it.

Unfortunately that wont work for my method. My method is simply a camera  
with a repeated spherical warp normal - one for each eye. so it's not  
physically correct, it just works in one render :)

Can you give me an example of how to do this? ATM the only other method I  
can think of is two renders stitched together in Photoshop.

Among the headings in Chapter IV:

* Chemical and Mechanical Deposits.
* Cementing together of Particles.
* Hardening by Exposure to Air.
* Mineralization of Organic Remains.
* Impressions and Casts: how formed.
