"Gravitational Composition II"



Author:TAKASUGI Shinji
Format:JPEG, 640 x 480 x 24bit
Software:Borland C++
Fractal: Julia set of Newton-Raphson method

Newton-Raphson method was applied for f(z) = z5 - 1
The height h was determined as follows:

z0 = (x2 + y2)1/4 exp((atan(y / x) + sin((x2 + y2)1/2))i)
zn+1 = zn - f(zn) / f'(zn)
dn = the distance between zn and its nearest solution
h = limn →∞ 1 / (2-n log dn - 1)
Texture: Flannel shirts and a muffler.
Rendering Time: 42 minutes for 1600 x 1600 x 24bit on 486DX2/66MHz, 28M RAM, OS/2 Warp 3.0J
