Here is a fractal I have been using to test improvements to Fracton's 3D Model Export. I switched from a grid based approach to a more sophisticated algorithm that searches for the edges of the fractal. Here is a quick loading web page with a few pictures and a short QuickTime movie that flies through the fractal. http://www.fracton.org/fmlposts/halley_jjp.html If you would like to view the fractal in FractInt, here is the parameter file. The complex parameter p1 is the exponent. halley_jjp { ; Exported from Fracton. reset=2004 type=formula formulafile=fracton.frm formulaname=F_20101016_1116 passes=1 float=y center-mag=0.4115234375000001/0.002148437499999963\ /0.8533333439999999/1/-90/0 params=7/0/0/0/0/0/0/0/0/0 maxiter=100 proximity=0 colors=UzJ<2>znP<1>B`3<4>H1C<3>i6X<2>znP<237>znP } frm:F_20101016_1116 { ; Type: Halley ; From Computers, Pattern, Chaos, and Beauty by Clifford Pickover ; See p277 for a related image and formula derivation ; Formula and par by Mike Frazier, public domain z=pixel: lz=z, f=z^(p1+1)-z,; Function z(z^p1-1) f1=(p1+1)*z^p1-1,; First derivative f2=(p1+1)*p1*z^(p1-1),; Second derivative z=z-2*f*f1/(2*f1*f1-f2*f), abs(|z|-|lz|)>=0.01 } -- Mike Frazier www.fracton.org
