I didn't use POV, I made a program in Matlab and exported the resulting
matrix to a 48-bit PNG. I had to do extensive image processing to stretch
the contrast and luminosity of the image and some minor cosmetic
adjustments.

I also had the idea of adding different values for the colors of the pixels.
Basically, the colors are related to the change in position. The bigger the
change, the more intensity is put into the pixel.

I used 10 million point. If I have time, probably I'll do a 100 million
points.

The image was generated in 3 minutes and less than 200 Mb of RAM.

I hope you like it.

Fernando

I do!

can you explain further, how you colored it? How bright is a
pixel and what color does it have depending on what values?

Thanks,
    Manuel

100 million points :)

and a different color scheme. I must go to class now, but I'll post my
coloring scheme soon.

Great! I love those colors! (And I got a new wallpaper, too :)

Could it be possible to zoom-in a little, so we don't see it is 
contained in a sphere.  And would it be possible to have it rendred in 
at least 1280x1024?  I'd love to have it as my desktop image!

Nice work!

BTW, it reminds me of a screen-saver in linux that animated such kind of 
thing... it was called 'strange' I've included a screenshot.

Here's the Matlab code based on your POV code.

I changed a few of the variable names, but it should be understandable.

Here's the basis for the coloring:

Red = change in x coord
Green = change in y coord
Blue = magnitude of the curvature (estimated)

I hope I made myself clear.

Thanks! Yes, I remember that screensaver in linux. There's another one,
called 'flow'. I love that one.

Here's the URL where you can find the wallpaper version of the image

Is it possible to get the Java-Source of your programm? I would like to 
play around with it.

Not Java, but Matlab :)

Anyway, the syntax is very similar I think.

If you have any question, let me know.

Fernando

flow is also very nice, but my prefered one is IFS...  and I hope I'll 
get to remake it with OpenGL one day!
