FOTD 22-12-10 (Everyday Event [5])
by Jim Muth 22 Dec '10

22 Dec '10

FOTD -- December 22, 2010 (Rating 5) Fractal visionaries and enthusiasts: Today's image is a very lucky one. My finger was one inch from the delete button that would have sent it to neverland when I decided to make it FOTD for the day. Nothing is really wrong with the image, but nothing is really right either. It's an *everyday event*, the kind of image I turn up all the time in my never ending search for a better fractal. This is what I named it. The formula behind the image is Z^(1.95)+C, iterated at ground level. The parent fractal is quite a bit more distorted than what might be expected from a formula so close to Z^2+C, but all the parts are there, even though they are not so easily recognized. There is nothing wrong with the rating of a 5. It's equal to a grade of 'C', which means average performance. If its calcula- tion time had been a bit faster than 6 minutes, the image might have rated a point higher. Those who do not calculate may view the finished image on the new FOTD web site at: <http://www.emarketingiseasy.com/TESTS/FOTD/jim_muths_fotd.html> The original web site is still there, though it is not up to date. The original site may be accessed at: <http://www.Nahee.com/FOTD/> Wall-to-wall sunshine and a temperature of 36F +2C made the shortest day of the year somewhat pleasant here at Fractal Central on Tuesday. The fractal cats must have agreed, for they spent most of the day on the shelf by the sunny southwest window. Most everything else went according to plan. The next FOTD will be posted in 24 hours. Until then, take care, and they say it's all a dream.

FOTD 21-12-10 (Test Pattern [6])
by Jim Muth 21 Dec '10

21 Dec '10

FOTD -- December 21, 2010 (Rating 6) Fractal visionaries and enthusiasts: Today's image shows a minibrot of order 1.1. For some reason I continue to search for interesting minibrots down in this range, even though I rarely find anything worthwhile. (Today's image shows a rare exception.) The parent fractal of today's image came about when I calculated the formula Z^(1.1)+C at a level 11 turns up the logarithmic hyper-spiral with no function applied. This parent is shaped like a cut-off parabola with a few areas of chaos along its edges. Not surprisingly, today's image is found in one of these chaotic areas. I named the image "Test Pattern" because of the flat, highly colored, sharp-edged shapes filling it, which might be only a test of what might lie deeper in the parent. The rating of a humble 6 indicates that I do not consider it one of the better FOTD images. With a calculation time of a mere one-minute however, the image is worth the effort despite its modest achievements. Calculation may be totally avoided by viewing the finished image on the currently active FOTD web site at: <http://www.emarketingiseasy.com/TESTS/FOTD/jim_muths_fotd.html> The classic FOTD web site at: <http://www.Nahee.com/FOTD/> might not be up to date, but it is worth a quick check. A mix of sun and clouds, with a high temperature of 34F +2C, made Monday pretty close to normal here at Fractal Central. The fractal cats spent their time alternating between the shelf over the heat and the shelf by the window, which is also pretty close to normal. The rest of the activity at FC was totally routine. The next FOTD will be posted in 24 hours. Until then, take care, and maybe we're all serfs, laboring on the lands of our overlords, the big corporations.

FOTD 20-12-10 (Holiday Seasons [5])
by Jim Muth 20 Dec '10

20 Dec '10

FOTD -- December 20, 2010 (Rating 5) Fractal visionaries and enthusiasts: Today's image is another quickie, worth only a 5. Something is wrong with the colors, (muddiness), and this keeps the rating at such a modest level. But with a rather fast calculation time of 4 minutes, the image is still worth at least a brief look. The name "Holiday Seasons" refers to the mood here at FC on Sunday as I was trying to find a fractal and make holiday preparations at the same time. The image lies in one of the typical double-negative fractals that results when various portions of Z^(-1.6) and Z^(-6.1) are mixed together and (1/C) is added. There are two ways to view the image: first, by running the included parameter file and seeing it almost at once; second, by checking the current FOTD web site at: <http://www.emarketingiseasy.com/TESTS/FOTD/jim_muths_fotd.html> where, if the image is not already posted, it soon will be. And keep checking the original FOTD web site at: <http://www.Nahee.com/FOTD/> It's far too early to give up on it. Sunday here at Fractal Central began with a temperature of 14F -10C, and with total sunshine, reached a high of exactly freezing. And speaking of freezing, the Susquehanna River, which flows only 1/4 mile from FC, is almost frozen solid, the first time I have seen it so. The fractal cats, who will never see the river, spent the day on their comfortable shelf over the heat. The shelf has become a surprisingly big hit with them. FL spent much of the day watching a couple of those latin soap-novellas. The next FOTD will be posted in 24 hours. Until then, take care, and do well.

Fractint under Windows Vista
by Bob Lester 19 Dec '10

19 Dec '10

Good Day to everyone, I've been following the discussions lately about running Fractint under various platforms, DOSBOX (never heard of this before), etc. I absolutely LOVED the DOS version of Fractint but have not been able to use it for a long time now with the advent of the newer Windows OSs. I don't have the experience in computer operations that a lot of you here obviously have. I would really like to be able to use DOS Fractint again. How would I go about setting it up to run under Windows Vista? I would need a very detailed listing of what to do. My computer is an Acer Aspire M5100, 32 bit OS, AMD Athlon 64 X2 Dual core processor 4400+, 2.30 GHz, 3GB of RAM. Thanks for your attention! Bob Lester

. My Alienware has Athlon 64 dualcore, GeForce 8600, it is about 4 years old, WinXP Media. And it runs fractint screamin' demon fast - all i do is click on the file. My other system is a pig. I think it is hardware, NOT WinXP itself - this proves it. For running animations (thousands of images, 24/7 for long periods), I boot up with a DOS boot CD and use a FAT partition on the HD - works fine. This may be a good option for all you with modern systems also. .

FOTD 19-12-10 (Theme and Variations [7])
by Jim Muth 19 Dec '10

19 Dec '10

FOTD -- December 19, 2010 (Rating 7) Fractal visionaries and enthusiasts: Today's image is a variation on the theme of the western suburbs of the large minibrot on the main spike of the Mandelbrot set. Even though the image is so distorted that nothing at all of the Mandelbrot shape remains, the name "Theme and Variations" still seems appropriate. Perhaps a name like "Fiery Cataclysm" would have been more appropriate. There certainly is a suggestion of an erupting volcano in the image. The extreme distortion was achieved by applying the exponential function to initial C, which in effect places the viewer in the middle of the fractal. The color palette is merely a slightly tweaked version of the Fractint default palette, which is for test purposes and pretty terrible as color palettes go. But in today's image the exaggerated colors give just the right touch to the scene. The more adventurous might check deeper into the solid parts of the chaotic areas. They hold a nearly limitless variety of Moire patterns. The rating of a 7 is on the liberal side, and the calculation time of 8 minutes is admittedly slow. The way out of this dilemma is to stop by the new web site at: <http://www.emarketingiseasy.com/TESTS/FOTD/jim_muths_fotd.html> where the completed image soon will be posted for immediate gratification. The original FOTD web site may be accessed at: <http://www.Nahee.com/FOTD/> though I have not checked to see if it is up to date. The temperature actually rose well above freezing here at Fractal Central on Saturday, to a high of 36F +2C, with lots of sun for good measure. But the milder weather was too little for the fractal cats, who spent most of the day on their new favorite spot -- the shelf over the large radiator in the hallway. Except for a brief sprint for some last-minute seasonal stuff, my day was quiet enough. The next FOTD will be posted in 24 hours. Until then, take care, and I sometimes wonder whether the faculty of reason is up to the task.

. DOSBOX rocks? Uhh ... maybe, but why not just use real genuine DOS ? You gotta be losing some performance with all the hardware/software translation in any emulation setup. What am I missing here? Does a given fractal actually render faster in DOSBOX on a current system then it would in DOS/Win9X on a P3-933 for example? .
