<Albrecht> Thanks for the MFR020F valentine!

Albrecht, All, Thanks for the MFR020F par file. I'm pretty sure that my DOS Fractint calculated it correctly (it's a red heart). I'm glad that your Fractint email list serve problems appear to be over. You said: > saw that the par-file was corrupted again. ... > Maybe someone can tell me how to avoid this bug. My understanding is that many email systems don't like long lines in their text. The email system automatically divides long lines into two or more pieces and places them onto separate lines. Fractint has a feature that allows controlling the length of the lines written when writing out a fractal's parameter file. I don't know whether any other fractal software has this feature. To control the line length when writing out parameter files in Fractint: - while viewing an image, - type <b> - type <down-arrow> to highlight the "Maximum line length" setting. - I set this to 55 and this length doesn't seem to bother email systems. - set any other parameters as needed - type the <Enter> key to write out the file. This long line length problem is most bothersome when a very long web address is cut in half and only the first half is treated as a link by the email system. (What the email system thinks is a link is usually underlined and colored blue.) When a "half-an-address" is clicked on, the intended web page *fails* to load. In these situations one can manually copy and paste the 2nd half of the web address onto the end of the 1st half of the address in your browser's address bar (address text window) to get the page to load. By the way, I also had to correct the name of the formula in the *parameter* definition to make the case of the letters exactly match the case of the letters in the formula definition: Multifractal_ni versus: multifractal_ni to get the parameter and formula file accepted by DOS Fractint. - Hal Lane ######################### # hallane(a)earthlink.net # #########################

FOTD 03-04-11 (Deceptively Simple [8])
by Jim Muth 03 Apr '11

03 Apr '11

FOTD -- April 03, 2011 (Rating 8) Fractal visionaries and enthusiasts: Today's image appears to show a minibrot near the surface of the Mandelbrot set, most likely the large minibrot on the west branch of the filament extending out from the large period-3 bud on the north side of the main bay. Well, in a way this is right, but appearances can be deceiving. The scene does show such a minibrot, however the filament it lies on does not extend from the main period-3 bud, it extends from the period-3 bud of a minibrot near the tip of the main spike of the M-set, at a depth of over 10^33, a depth that is not to be sneezed at. The thing that granted the image the honor of being declared FOTD is the smoothness of the color bands, almost giving the impression of a true-color image. (Such as those *other* fractal programs create.) A curious change may be achieved by resetting the bailout to the default 4. In fact, some may prefer the added detail achieved, though I prefer the pseudo-true-color smoothness. The name "Deceptively Simple" refers to the surprisingly large magnitude of the scene. The smoothly blended coloring earned the rating of an 8. If I had worked harder, I might have totally eliminated the color bands and raised the rating to an 8-1/2. The calculation time of 11-1/2 minutes is quite fast considering the arbitrary precision math and the magnitude. The finished image may be viewed on the active FOTD web site at: <http://www.emarketingiseasy.com/TESTS/FOTD/jim_muths_fotd.html> Don't forget the original web site with all the past images at: <http://www.Nahee.com/FOTD/> My own web site needs only a brief written introduction to fractals before it will be ready to face the judgement of the fractal world. Saturday turned rather pleasant and sunny enough, though a bit chilly for the season. The fractal cats would have preferred things a bit warmer, but were happy enough with the temperature of 52F 11C. The day of the humans was busy, which is getting to be a routine condition here at FC. The next FOTD will be posted in 24 hours. Until then, take care, and never be a slave to common sense.

Hi, saw that the par-file was corrupted again. In order to run press "delete" at the end of the line previous to the "\", so it is at the correct spot. Maybe someone can tell me how to avoid this bug. sincerely, Albrecht

FOTD 02-04-11 (An Island Universe [7])
by Jim Muth 02 Apr '11

02 Apr '11

FOTD -- April 02, 2011 (Rating 7) Fractal visionaries and enthusiasts: The minibrots in some fractals are connected to the main body of the larger fractal in which they exist. The minibrots surround- ing the Mandelbrot set are all connected by thin filaments to the main body of the M-set in this manner. Other minibrots have no connection to the rest of their fractal, and exist as island universes, scattered around the fractal's main body like moons frozen in time. Today's FOTD image shows one of these disconnected minibrots. The parent fractal is a tiny Mandelbrot set surrounded by a cloud of minibrots, which in turn are surrounded by smaller clouds of minibrots, etc, etc., all the way down. The image shows a minibrot near a larger minibrot in one of these sub- clouds. Since the larger minibrot is itself disconnected, the pattern surrounding the minibrot in today's image consists of disconnec- ted patches, filled with still smaller clouds of minibrots, all of which are well beyond resolution. In my fractals, I usually try to avoid overly busy and brilliant colors, but in today's image the excessively gaudy color palette actually seems to improve the overall appearance. If I had had more time, I might have gotten a bit more action from the under- lying iteration bands, but even as the image is, it earns its place as FOTD for April 02. The name "An Island Universe" tells it like it is. The image is part of an island, and it has a universe within its depths. The rating of a 7 is becoming so common that the FOTD rating system is starting to become redundant. The calculation time of a fireball 18 seconds seems too good to be true, but take my word, the image calculates in just that time. Another way to see the image is to view it in finished form on the currently active FOTD web site at: <http://www.emarketingiseasy.com/TESTS/FOTD/jim_muths_fotd.html> The venerable original FOTD web site is still available at: <http://www.Nahee.com/FOTD/> My own web site is almost ready. All I want to do is prepare a proper home page with a brief introduction to the world of fractals. I have also decided to include a gallery of several hundred images that I saved to disks in the years before I began the FOTD. These old images, which go back to the late 1980's, were created with various fractal programs. Most have no parameter information embedded. They are not up to current standards, but they are still interesting images, showing how I launched my fractal explorations. Friday here at Fractal Central began with wet snow that melted as it fell. By midday the snow had changed to rain, which slacked off to sprinkles in mid-afternoon and ended by sunset. The temperature reached a chilly high of 43F +6C, keeping the fractal cats within leaping distance of the heat. The rest of the day was filled with routine everyday stuff such as making money. The next FOTD will likely be posted in 24 hours. Until then, take care, and if you know what a lemac is, you're probably not a teen-ager.

<Albrecht>Is this the correct fractal?
by Hal Lane 01 Apr '11

01 Apr '11

Albrecht, all, You said: > hope YouÂ´ll like this image. I do. > Please advise, if You have any difficulties generating. > Probably will not run under Windows. If the image I calculated is the one you created, then, yes, I like it a lot. Is this (below) the correct fractal, Albrecht? I adjusted the .PAR info and calculated the image using DOS Fractint 20.04.4 under WinXP. Here's the adjusted version of your .PAR file that I used: http://www.emarketingiseasy.com/TESTS/FOTD/MFR149F.PAR I also applied Damiscena Korwin's Leather Gem color map. Her 1998 Fractal Art Contest entry Leather Gem is here: http://www.fractalartcontests.com/1998/entries/01-013.htm My anti-aliased 1200x900 pixel image is here: http://www.emarketingiseasy.com/TESTS/FOTD/MFR149G.jpg For the adventuresome who might be interested in the greater (unanti-aliased) detail in the image before it was downsampled, here's the 3MB 4096x3072 version: http://www.emarketingiseasy.com/TESTS/FOTD/MFR149F.gif Both Firefox & IE7 can show the large file OK on my WinXP system. Be sure to click the image once to see it at full size. (I like to use an image viewer that allows me to "drag" different areas of an oversize image onto the screen -- instead of having to find and "aim for" and exactly "hit" the scroll bars in my browser.) - Hal Lane ######################### # hallane(a)earthlink.net # #########################
