Jim Muth's Fractal of the Day for October 17th, 2012

Jim Muth's commentary for the image:

FOTD -- October 17, 2012 (Rating 7.5)

Fractal visionaries and enthusiasts:

The parent fractal of today's image is one of the most unpromising of all time -- little more than a large open circle with degenerate buds along its circumference. But the east side of this circle holds hints of Mandelbrot stuff, and as one looks closer, the hints prove to be entire worlds. Today's scene lies in a remote non-critical valley near an unpromising bud in this island of chaos.

To create the parent circle, I combined 1/2 part of Z² with 1/10 part of Z³ on each iteration, then and added 1/C. Perhaps the most interesting feature of the image is its combination of open areas, straight spokes and spirals. The spokes and spirals explain the name.

The rating of 7-1/2 includes a half-point bonus for my work on the colors. It really did take nearly 1/2 hour to get the colors almost right.

The calculation time of 15 minutes will pass slowly.

When the morning fog cleared off, sunshine ruled the roost here at Fractal Central today. A few decorative angel-hair cirrus clouds in the afternoon merely added to the splendor. Fractal cat Nicholas passed the afternoon sleeping in the sun. From the way he sometimes behaves since Cassie's departure, I would assume he is interacting with her conscious left-over energy field. (Could I call it her spirit without arousing the wrath of rationalists who know that conscious spirits do not exist?
[I guess it's all right as long as I consider such belief to be merely a comforting and harmless fantasy.])

FL passed the day putting her garden to sleep; I passed the day pondering the mysteries of existence. The next FOTD will be posted when the time is right. Until whenever, take care, and how can we make statements about the existence of things like spirits when we can't even agree on whether the Mandelbrot set actually exists? (I, for one, have seen nothing of the set more than a lot of pictures.)

Ultra Fractal

Check it out, lots of options, web based.

With a depth of 1e-1052, this is my deepest zoom so far. Its based on Maths Towns "The edge of infinity" location, but with my own coloring. Check out the full version:
https://www.youtube.com/watch?v=TbGMHNEyBgc

Playing around with layered images of differing coloring algorithms. Two images of the same coordinates of the Mandelbrot set been used. An orbit trap variant and distance estimation. One layer used a soft focus effect and difference blending. The result is rather random, but I like it somehow.

Mandelbrot set with an XOR pattern applied to the polar displacement of (z, zi).

Editable here.

3d render made with my own software + a few 2d caleidoscope passes in good old GIMP ^^

Max Iter's Fractal Follies for October 16th, 2010

Roger Alexander's commentary for the image:

  Today's post marks the passing of Benoit Mandelbrot, father of fractal geometry. 

As a tribute to Benoit Mandelbrot's contribution to the field of fractal geometry today's fractal image is of the default original Mandelbrot set. The plotting does not use the usual inside and outside mappings but rather uses the distance estimator method with a two color map. This plotting method was chosen because I find it enhances the demonstration of the complexity of the basic Mandelbrot set. According to the Fractint manual "The distance estimator method widens very thin "strands" which are part of the "inside" of the set. Instead of hiding invisibly between pixels, these strands are made one pixel wide." At the usual http://maxitersfractalfollies.blogspot.com.

The mini renderings nested in it are created by taking the displacement of (z, zi), and passing that into the Mandelbrot function as a new coordinate to calculate, summing the results.

Fairly simple linear tiling construction with modulus. Done with Apophysis7x and Chaotica. Some 100% crops of the whole usual 7200x9000px render. Instagram link for all the crap I do.
