Tangling Tendrils
by Mike Frazier 29 Mar '16

Here is an animation of a fractal I found back in 2012. The fractal mixes z * (cosh(z) - 1) and z * z * sinh(z) at locations -1 and +1. Varying the locations of the two components causes the tendril arms to be more or less curled. The animation moves the locations by changing the parameters p3 and p4 from -1.1 to -0.8 and +1.1 to +0.8. Moving the component locations also causes the center of the desired area to move so the animation moves the fractal center to follow that as well. To keep the render time reasonable I made the movie only 5 seconds long (61 frames). It still took 1.5 hours to render. Here is a link to the movie (2.5 MB): http://dl.dropboxusercontent.com/u/33642054/image/pr_3cosh-3sinh_F.mov Here is a link to an image at about the 1/3 point of the movie at locations -1 and +1: http://dl.dropboxusercontent.com/u/33642054/image/pr_3cosh-3sinh_F_640_5.jpg The FractInt compatible PAR file for the image is: TanglingTendrils { ; Exported from Fracton. reset=2004 type=formula formulafile=fracton.frm formulaname=F_20160309_1314 passes=1 float=y center-mag=0.008301665151149345/0.1582340776519129\ /566.2672882912181/1/0/0 params=-1/-1/0/4/-1/0/1/0/0/0 maxiter=2000 inside=0 periodicity=6 colors=000C10O40ZA0hI0oS0ua0ym0zy0ym0ua0oS0hI0ZA0O\ 40C10000C10O40ZA0hI0oS0ua0ym0zy0ym0ua0oS0hI0ZA0O40\ C10000C10O40ZA0hI0oS0ua0ym0zy0ym0ua0oS0hI0ZA0O40C1\ 0000C10O40ZA0hI0oS0ua0ym0zy0ym0ua0oS0hI0ZA0O40C100\ 00C10O40ZA0hI0oS0ua0ym0zy0ym0ua0oS0hI0ZA0O40C10000\ C10O40ZA0hI0oS0ua0ym0zy0ym0ua0oS0hI0ZA0O40C10000C1\ 0O40ZA0hI0oS0ua0ym0zy0ym0ua0oS0hI0ZA0O40C10000C10O\ 40ZA0hI0oS0ua0ym0zy0ym0ua0oS0hI0ZA0O40C10000C10O40\ ZA0hI0oS0ua0ym0zy0ym0ua0oS0hI0ZA0O40C10000C10O40ZA\ 0hI0oS0ua0ym0zy0ym0ua0oS0hI0ZA0O40C10000C10O40ZA0h\ I0oS0ua0ym0zy0ym0ua0oS0hI0ZA0O40C10000C10O40ZA0hI0\ oS0ua0ym0zy0ym0ua0oS0hI0ZA0O40C10000C10O40ZA0hI0oS\ 0ua0ym0zy0ym0ua0oS0hI0ZA0O40C10000C10O40ZA0hI0oS0u\ a0ym0zy0ym0ua0oS0hI0ZA0O40C10000C10O40ZA0hI0oS0ua0\ ym0zy0ym0ua0oS0hI0ZA0O40C10000C10O40ZA0hI0oS0ua0ym\ 0zy0ym0ua0oS0hI0ZA0O40C10 } frm:F_20160309_1314 { ; Similar to the parallel resistance formula a=real(p1),b=real(p2),d=imag(p1),f=imag(p2), z=0,c1=pixel-p3,c2=pixel-p4: z=1/(1/(a*z*(cosh(z)-1)+c1)+1/(d*z*z*sinh(z)+c2)), |z|<100 } -- Mike Frazier www.fracton.org

I have a Cubby link of Albrecht's that works -- and he has previously given me permission to host images of his on my server -- so, when I found a few interesting images of his that I hadn't seen before, I thought I'd make them available to anyone who would like to see them: Notes: The leading 2 digits & "_" were generated by Cubby cloud hosting service.

FW: Please post [this animation] to the list - From JoTz

> Please post to the [Fractint] list. Sure. Very nice animation! I like to watch everything go by at 1/2 speed so I can see a little more of your detail before it's zoomed off the screen: For: Windows Media Player: Right click window frame > Enhancements > Play speed settings > slider: 0.5 The motion is still smooth enough to not appear as stepping between frames at this speed. At (0:47...) I like the "figure/ground" effect from the pale background glowing "behind" the fractal. I'm wondering how you found the central figure that appears at (1:00)... It initially seemed similar to other areas in the image -- but, what a difference! Stopping playback at (1:13) and (1:17) give very nice still images. Thanks, JoTz! - Hal Lane ######################## # mailto:hallane@earthlink.net ######################## From: LLOYD GARRICK [mailto:lgarr@colorado-hiking.net] Sent: Tuesday, March 8, 2016 9:42 PM To: Harold Lane <hallane(a)earthlink.net> Subject: Please post to the [Fractint] list I finally succeeded in animating one of the recent Mike Frazier "electronic" fractals; the pattern is very complex, rivaling Niekamp's works. Difficult to color however; I scanned over 400 MAP files in my collection, found only about 4 that were acceptable. Again, compressing the video would make it pointless, so I upload the hi-rez AVI file, 600MEG for 100 seconds. http://www.fractal-animation.net/special/DeepPurple800.zip Enjoy!

Slow down

Quite a few of us have health concerns. Most likely you find that this interferes with a steady learning and creative endeavor. Why be informed and creative ; because this is how we overcome the limitations that have always been imposed upon us . For most persons the harsh reality of our situation is something that's just beyond our comprehension and many shy away from even contemplating this whilst others over indulge in contemplating their mortality. I'm in both categories. So my request to YOU , consider how fractint knowledge might be applied to solving some of these problems . Edward.

A Fractint box?

If I were just a little younger and less shaky I'd be tempted to solve Jim's problem by— " Run DOS on the Raspberry Pi – Use rpix86 to turn your Pi into a 1980s supercomputer " . John W.
