All my investigations of Jim's FOTX -- June 03, 2016 are (unless otherwise noted): - 5X oversampled (to 27 mega-pixel images) - anti-aliased with slight sharpening Full size image viewing recommended. Jim's FOTX -- June 03, 2016: http://www.emarketingiseasy.com/TESTS/FOTD/2016/F160603.jpg The FOTX's "parent" fractal: http://www.emarketingiseasy.com/TESTS/FOTD/2016/F160603Z.jpg Out the negative X-axis and up a little in Y has this area: http://www.emarketingiseasy.com/TESTS/FOTD/2016/F160603Y.jpg A zoom into the center of "Y": - MaxIter changed from 1500 to 3000 http://www.emarketingiseasy.com/TESTS/FOTD/2016/F160603X.jpg I believe the large red areas in the images are a product of: - the range of values produced by Fractint at this magnification, plus - Jim's having to use work-arounds (if I understand him correctly) in creating his color map because Fractint's LogMap feature did not function correctly for this fractal. Jim's color map: http://www.emarketingiseasy.com/TESTS/FOTD/2016/F160603M.jpg I very rarely change Jim's color maps in any way -- except to remove any non-zero LogMap value when rendering a fractal's "parent" and the first few zooms into it, if Jim has used Fractint's LogMap feature. I do this because it gives a much better parent image. If I do make changes to his color map, I always let you know how and why. A zoom into the center of "X" reveals mostly very garbled-symmetry Mandeloids: - MaxIter changed from 1500 to 6000 http://www.emarketingiseasy.com/TESTS/FOTD/2016/F160603W.jpg Those odd circular areas between/around the bays in "W" appear to be some more of the "anti-minibrots" Jim describes in his post (forwarded below.) Here's one, shown in its surroundings: http://www.emarketingiseasy.com/TESTS/FOTD/2016/F160603V.jpg You can see the number of elements decreasing as the circles get smaller: 16, 8, 4. - Hal Lane ######################## # hallane@earthlink.net ######################## -----Original Message----- From: Fractint [mailto:fractint-bounces@mailman.xmission.com] On Behalf Of Jim Muth Sent: Friday, June 3, 2016 3:15 PM To: fractint@mailman.xmission.com Subject: [Fractint] FOTX -- June 03, 2016 FOTD -- June 03, 2016 (Rating A-8,M-9.5) Fractal visionaries and enthusiasts: Hopefully, I now have the dates in order. These mixed-up dates are what happens when I find fractals on one date and post then on a different date. Today's FOTX shows a rather colorful basin of attraction around a minibrot near the tip of the negative X-axis of a Mandelbrot set that has been corrupted in its depths by mathematical energies of the sixth order. But look closer! Something is not right. The color palette rotates in the wrong direction. The point at the center is not a pit that wants to suck everything into a minibrot at its center; it is a hill that repels everything from the peak at its center. And the number of elements converging on the center does not keep doubling in powers of two as we go inward; it keeps being divided in half, from 16 at the outer edge to 2 at the center. And the actual center is not an open hole; it is a blank area of the lowest iteration count surrounded by higher iteration stuff -- an anti-minibrot! Unfortunately, the center part of the image lies beyond the range of resolution, but we can come close enough to see that the number of elements there has divided to 2. Nothing lies beneath the number two but the ultimate fractal oblivion of unity. One problem of today's anti-minibrot is that with the higher iteration stuff lying around the edges, Fractint's automatic logarithmic color palette, which is activated by entering the numeral 2, does not work. It leaves the center of the image, where the number of elements divides to two, a featureless flat area. This curiosity is not too bad in today's image, but I have seen it result in an almost totally blank screen. Most of the shapes in the image were created by rendering it with the outside set to 'tdis', which colors the points according to how far they have traveled before escaping. (The points closer to the center of today's image have not gone very far.) The extra brilliancy of the colors was created in a separate color manipulation program. (It's not a sin, since Fractint drew the shapes.) In my opinion, the art value of the image rates an 8. Its vivid colors put it at least a little above the average. But the math rates a superlative 9.5, since these anti-minibrots are some of the most unusual things I have yet discovered in the world of fractals. The day here at Fractal Central left much to be desired. The high temperature of 79F 26C was fair enough, but occasional rain kept a damper on things. The fractal cats spent the day in the watch window, watching for other cats. The other cats spent the day keeping dry. The fractal humans simply made it through another day with nothing unusual happening. The next FOTD will be posted whenever it is. Until that unknown moment arrives, take care, and watch for those quantum erasers. No one knows exactly what they might do.
