'Black Pearls on pseudopods in ChaosLand'
by Hal Lane 29 Mar '07

29 Mar '07

######################################################### This is a zoom into Doug Stewart's fractal 'Suspended,' which is derived from Jim Muth's FOTD 07-03-28. The color map is the rotated 'Sunfish' color map from David M Fisher with black added for the 'lake.' This image could be called 'Black Pearls on pseudopods in ChaosLand.' I was able to count about ten complete cycles through the color map in the image -- which is a range of iterations of about 10 x 512. This means that I was able to see pixels that had at least 5000 iterations of the mandelbrotmix4 formula. In actual point of fact I believe that the image has many more iterations per pixel on average because of the fact that the image took about 20 seconds to calculate one horizontal row of pixels that had no 'lake' pixels in it on my 400MHz Pentium II. My setting the maxiter= to 16000 lets the details at the edges of the 'lake' features be crisp. The 1280x1024 version of this image took more than 7 hours to calculate so if you calculate it I would recommend your using Fractint's "Disk" Video mode and letting it calculate while you do something else. Calculating the image at this high resolution allows the pixels in the chaotic areas to turn into an almost invisible 'pixel broth.' - Hal Lane ######################### # hallane(a)earthlink.net # ######################### START PARAMETER FILE======================================= Suspended_F070328E { ; Hal Lane 07-03-28 7:18:09 P400 ; 1280 x 1024. ; Fractint Version 20.04 Patchlevel 4 ; Zoom into Doug Stewart's fractal: ; 'Suspended,' a zoom into Jim Muth's ; FOTD 07-03-28.

How to fix Doug Stewart's "second pond in Jim's FOTD" PAR file
by Hal Lane 28 Mar '07

28 Mar '07

######################################### Doug, it turns out that the name for your fractal: dougs_fotd_03_24_07 in your par file has one more character than Fractint allows. I just dropped an underscore ("_") from the name and the fractal now calculates fine. I also tried raising the maximum iterations to 2.5 million to see if the pond filled in more. It did, but not too much. - Hal Lane ######################### # hallane(a)earthlink.net <mailto:hallane@earthlink.net> # ######################### >-----Original Message----- >Date: Fri, 23 Mar 2007 22:11:12 -0500 >From: Doug Stewart <dastew(a)sympatico.ca> > >Subject: [Fractint] A second pond in Jim's FOTD for march 24 07 >To: Fractint and General Fractals Discussion > <fractint(a)mailman.xmission.com> >Message-ID: <460496D0.5050501(a)sympatico.ca> >Content-Type: text/plain; charset=windows-1250; format=flowed > >Thanks Jim!

RE:<Richard> [Fractdev] 'o' (Orbits) works again
by Hal Lane 28 Mar '07

28 Mar '07

Richard said: >I removed mem_init and mem_alloc and replaced them with >malloc() and free(). 'o' works again. [In my personal copy of the developer's Windows port of Fractint.] [I believe that this 'orbits fixed' version is not yet available in a Windows' beta -- but you can see the Fractint <O>rbits option using the original DOS Fractint using the instructions below. - HHL.] Great! When I use 'o' (orbits) I find that today's processors are so fast and screens so large that the tiny pixels showing all the calculations are lit up so fleetingly as to be barely visible. Thank heavens the writing and 'erasing' of each of the 'iteration pixels' significantly slows down the overall calculation process to let you catch a fleeting glimpse of the 'orbits' pixels... I found that on the original DOS version of Fractint: - reducing the resolution to, say, 800 x 600, - turning off Periodicity on the <Y> screen and - setting Passes = 1 on the <X> screen can make the dancing pixels be large enough to see better. Turning up the brightness and contrast helps. <O>rbits works well on the default Mandelbrot set using a color map like GOODEGA.MAP. You just have to hit that <O> key quickly or the fractal will be mostly completed before it appears on the screen! Thanks for all your work on the program. - Hal Lane ######################### # hallane(a)earthlink.net <mailto:hallane@earthlink.net> # ######################### >-----Original Message----- >From: fractdev-bounces+hallane=earthlink.net(a)mailman.xmission.com >[mailto:fractdev-bounces+hallane=earthlink.net@mailman.xmission.com]On >Behalf Of Richard >Sent: Thursday, March 22, 2007 8:25 AM >To: Fractint developer's list >Subject: Re: [Fractdev] Out of memory errors > >I removed mem_init and mem_alloc and replaced them with malloc() and >free().

Re: DOS prompt
by jackoftradez＠comcast.net 28 Mar '07

28 Mar '07

Marty, I assume you have Win9X? Reboot and tap the F8 key every half second or so. You should get a menu of boot options. You can choose "command prompt only" or "command prompt safe mode". No need to use a floppy; also, some "non-MS" DOS versions are not fully compatible with windows if you want to do diagnostics or repair. You can configure Win9X to boot directly to DOS each time anyway normally (then type WIN to get to windows). With this you would not have this problem. .

FOTD 28-03-07 (FOTD for March 28, 2007 [Rating 5])
by Jim Muth 28 Mar '07

28 Mar '07

FOTD -- March 28, 2007 (Rating 5) Fractal visionaries and enthusiasts: Today's image lies in the fractal that appears when 6 parts of Z^(-1), which is (1/Z), are combined with one part of Z^(-2) and straight C is added. This parent fractal is not unusually prom- ising -- an oversized egg-shaped open oval with pointed ends and a string of circles mounted on stems, stretching down the mid- dle. There is almost none of the semi-chaos that promises good fractal hunting. But hope springs eternal in the breast of every devoted fractalist, and those who search deeply enough will find this parent fractal loaded with goodies. All right, I admit that I did render today's image with the inside set to 'fmod' and the outside set to 'summ', but a little something extra really was needed to bring the image to life. When rendered in my normal manner, with the inside=0 and the outside=iter, the resulting piles of flat splotches arehardly worth FOTD status. Though I rated today's image at a 5, I gave it no name. After studying it for 5 minutes, I saw nothing that reminds me of any- thing familiar. The 9-1/4 minutes required to run the included parameter file may be saved by going to the FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and viewing the image there. Unexpectedly warm weather arrived here at Fractal Central on Tuesday, when the temperature reached a high of 82F 28C. The plentiful sunshine and light winds made it feel more like mid- summer than early spring. Of course, the fractal cats did not concern themselves with the outside conditions. As long as it is reasonably comfortable inside, they do not complain about the weather. My day was again a little busier than I would have liked, but things are definitely slowing down. The slow-down should lead to better fractals, the next of which will appear in 24 hours. Until then, take care, and a fractal visionary, like all vision- aries, is one who sees things that others miss. Whether those things are 'real' or 'all in the mind' is irrelevant.

PAR for parent fractal of March 27, 2007 FOTD;
by Hal Lane 27 Mar '07

27 Mar '07

######################################################### Jim Muth often makes a comment about the appearance of the parent fractal that a FOTD image is calculated from. His description of today's FOTD encouraged me to create the parent fractal: >FOTD -- March 27, 2007 (Rating 6) > >Today's parent fractal came about when I combined 0.1 part >of Z^(10.5) with 1 part of Z^(1.05) and added straight C. >It reminds me of a Mandelbrot set with a clumsily trimmed >peacock's tail. ... Today's scene is located in the >peacock tail. The .PAR file below to create the parent image with the peacock's tail was easily created by: - calculating Jim's March 27th, 2007 FOTD, - repeatedly hitting <PgUp>, making the zoom box be as small as possible, - hitting the key combination <ctrl><enter> to calculate the new image formed when the original full screen-sized FOTD is shrunk to the size of the tiny zoom box -- ('zooming out' instead of 'zooming in'). - repeating the 2 previous steps until the original 'peacock's tail' image described by Jim appears. - hitting the <B> key to write the .PAR file. I have oriented the parent fractal differently than Jim did (I rotated and translated it) in the image created by the PAR file below -- to fit as much of it into a 3:4 aspect ratio image as possible. With this particular image if you create the parent fractal yourself, note that as you repeatedly zoom out you create a couple of completely dark blue screens. Have faith and zoom out 3 or 4 more times and you will see the 'clumsily trimmed peacock's tail" attached to the Mandelbrot set described by Jim. Feel free to rotate and translate the final image to better frame it as I did in the .PAR file below. To speed the process up, note that you do NOT need to wait for the current image to complete its calculation before you repeatedly hit <PgUp> to make the zoom box be the smallest it can be -- before hitting <ctrl><enter>. Here are two ways to get to Jim's 'clumsily trimmed peacock tail': 1) Give the PAR file for Jim's peacock tail below a try -- it only takes 30 seconds to calculate on a 400MHz Pentium II. 2) Also, please let me know of your success (or lack thereof) if you try the sequence of steps given above to get to the peacock tail. Be sure to use Jim's original FOTD PAR for March 27th, 2007 to create the first image and NOT the PAR below before you start zooming out. - Hal Lane ######################### # hallane(a)earthlink.net # ######################### START PARAMETER FILE======================================= FOTD27Mar07_parent { ; Hal Lane 07-03-27 0:31 P400 1024x768 ; Parent fractal of Jim Muth's Fractal ; of the day.

Re: [philofractal] PAR for parent fractal of March 27, 2007 FOTD;
by jackoftradez＠comcast.net 27 Mar '07

27 Mar '07

. Good technique Hal, I used to do that, sometimes still do. But there is an easier quicker way. Generate the original Muth image, then generate the PAR file from fractint (or you can just use Muth's posted PAR). Look at the "center-mag" numbers, usually there are six separated by a "/" character; you want the THIRD one - that is the magnification factor. Manually edit it in notepad to be a number corresponding to the parent default, like 0.667 in fractint for the Mandelbrot, or as in your case, 4.411155. Anywhere around 1.00 should do. Then calculate that image from the new PAR in fractint. I do this when investigating posted fractals from the "allinone" and "mandelbrotmix" type formulas Muth often posts. It is revealing to see the parent fractals - often quite bizarre and looking nothing like the zoomed-in. JoTz .

OT - Need a DOS prompt!
by Martin Krikorian 27 Mar '07

27 Mar '07

My apologies in advance for an OT post. Fellow Fractint Fanatics: My fractal explorations are on hold right now, as my PC refuses to boot because of a file my son downloaded. I can't even get to safe mode. I have figured out what to do to fix the machine, but I need to get to a DOS prompt, and I can't seem to do it. I made a rescue floppy with Dr DOS on it, but each time I try to exit to DOS I just get another re-boot. Can anyone pass advice as to how to get to a DOS prompt? Maybe a DOS only disk I could boot with? I have used PCs since before Windows existed, but the lack of what used to be basic tools (like floppies to boot from) has got me stymied. Marty K
