IMAGE DESCRIPTION: 

Many of the websites I visited while trying to get an idea for this comp. listed
Chaos as being part of Physics and fractal patterns as part of Chaos. The
defination of Chaos is something like a small change in a well defined equation
( or picture ) resulting in somthing that got totaly out of hand ( or something
like that. )
 
My intent was to construct an image composed as much as possible of fractal
shapes and Math formulas 
So for your consideration I present Kaos 

DESCRIPTION OF HOW THIS IMAGE WAS CREATED: 


Ceiling and Floor
  Each round tile is a seperate julia_fractal. These were set using a series of
loops. 2 plane were used for "grout"

Gray back wall
 This was made of indidual blocks with the mandel pattern used as a normal.

Green/white right wall
 This was made of indidual blocks with the mandel pattern used as a texture. Its
off screen and only in the mirror wall because I ran out of room.

Mirror Wall 
  There was a math reason having to do with symetry for putting this in, but I
forgot what it was. In any case having it allowed me to put more stuff in.

Wall Hanging
  Mandel texture.

So much for the easy stuff. The next job was to get PovRay to plot formulas. I
chose Sierpinski to start with because all the descriptions said it was
blindingly simple to program. Yeah, right. I ended up converting an old C demo
into Pov code.
 
Starting from left back: 
Sierpinski, Lorenz, GingerBread, Henon ,ButterFly

Left front:
Rossler, Forcefield

These are encased in Glass display cases and setting on julia_fractal bases

The Maze
  The formula for the partitions ( those would be the gray stone stretched
spheres ) came from a demo program called winfeed? 

The vegetation 
 Groups of Spleenwort ferns arranged tastefully ( or smashed together
haphazerdly depending on how many ferns you've already viewed ).

The tree size bushes are on a julia_fractal that kinda looks like a log if you
look real quick. The scaled down bushes in the center are in a hollowed out
box.

The Foutain
  The top spray of water is produced by a parabola formula.
The middle and bottom sprays of water are The Spleenwort fern again with just a
really tiny change in the formula

General

 I started out on useing spheres to plot with since they produced the
best results but with over 200000 frame level elements a 4 hour parse time and
an additional 6 hours to render the math portion of the picture I looked for a
better way.

The current version uses triangle meshs for everything but the maze.
There is one light sourse and the final render uses "alot" of radiosity. It
compiled and rendered in about eight hours.

The source code is provided. As usual I will accept no responsibility for damage
to your sanity from viewing it.
