Yet another try with the eval_pigment function

Maybe usful for lightning, wires, alien plants ...

I am working on some branching function

The textures on the objects are the same pigment used for eval_pigment

Comments ?

It's freaky and I don't understand it.  How's that for a comment?

Better than nothing :-)

For understanding: It works similar to a L-System, except there is no
branching (yet) and the rules are defined by the pigment:

-Direction according to the color values and a general "drift" direction
-size according to luminance

And of course the different lines use different multiplication factors.
The rest is cones and spheres.

I hope that made things clearer, If I have time to improve it, I will
also post the code.

Thanks, more clear, yes.  It's the image you rendered that is confusing me I
guess.  I was trying to see what pigments were deciding which
objects/transformations and wasn't getting anywhere so I gave up, thinking
maybe it was all unseen but you had said it was textured with the same...
Sometimes you can only waste time teaching me anyhow  ;-)
