Here are a couple of nice pics which resulted from
my playing around with fractal image programming, with the GIMP
and with the
raytracer POV-Ray. The fractal images were created in the full resolution
and then downscaled for this web site using anti-aliasing. The raytracing pics
were rendered anew in the desired resolution. Enjoy. (By the way, here is the POV-Ray source code for the mask on the side
as a gzipped tar file.)
Another raytracing picture: A glass
figure-eight knot and a brushed-steel dodecahedron frame float on a piece of
wood on a glittery sea, surrounded by a burning horizon. Here are the POV-Ray source files and the brushed metal image
map in a gzipped tar archive. The "brushed steel" look is from a
theme of the window manager IceWM.
My first raytracing picture, consisting
of a helecoid mirrored in a perfectly reflecting sphere. Here is a tar archive containing the two source files.
This is the fractal of Newton's method for solving
exp(z)=1. The starting points for which the iteration diverges to infinity are
plotted in black. The beautiful curved structure results from inverting the
complex plane with respect to the unit circle. A maximum of 50 iterations were
executed, and the conditions for aborting earlier were numerical overflow
(divergence) and a modulus <0.5 (convergence to 0). You can download the full-sized 1392x1990 image, in gzipped PCX
format.
The well-known Mandelbrot set, computed
with unusual zeal: The original picture was computed ages ago on an 8 MHz
Atari computer. It took several days to render and was large enough for a 140
by 120 cm poster in 180 dpi resolution. I have since repeated the calculation
on a 600 MHz Pentium III in under a minute. For poster freaks (and paint
program crash testers), here is the
full-sized 9712x8634 image, again in gzipped PCX format (512 kB). Also
available is the source code (Linux port, not
Atari version ;)), documented in German.
