Hi tracers!

Here I'm again with some cube fractals rendered according to K's (I
think it's the time for me to learn how to make a link to a Usenet
posting... any hints?) already about two weeks ago... a short
description of the variable names used in the captions:

sf: scale factor, size of each subsequent cube union relative to the
union before;
w: variation width of the randomized scale factor: note that in the
first four images, I used a simple arithmetical definition of the width
- after scaling the union by sf, it is rescaled according to the formula
(1+w/2)-w, so with an original scale factor of 0.5 and a width of 0.8,
the actual scale factor ranges between 0.3 and 0.7;
f: variation width in the other four pictures, but now geometrical:
sf*pow(f, 1-rand(seed)*2). An original scale factor of 0.5 combined with
a width of 3 would actually yield results between 0.15 and 1.5.

I think K's method would be quite useful to generate pyrite (fool's
gold) crystals, when used with an appropriate texture...

See you in Khyberspace!

Yadgar

very nice (more!)

try to avoid pure R G B colours, jpg compression really does not like it
