On 8 April 2006 I wrote: 'I have a puzzle. I've been using Fractint since 1991 and greatly appreciate the work of Jim Muth and Paul N Lee, as well of course the Stone Soup team.

'Secondly, if I render a fractal the process seems to go very slowly unless I move the mouse, when it speeds up. I find this odd. 'Third, after rendering the screens other than those with the image are randomly coloured and usually hardly legible.' Paul N. Lee kindly replied, saying, in part: 'You may also need to play with the various property settings that can be set for running the application, especially on the MISC and COMPATIBILITY tabs of the PROPERTIES, such as the IDLE SENSITIVITY.' I have now again had to accept the inevitable and upgrade to Windows XP Home -- again not without hassle, including among many things eventually having to junk my HP scanner as after 10 hours work and consulting HP support three times I couldn't get a driver for it. (The Canon replacement is much better.) I was surprised and delighted to find that I could run Fractint much as before, despite doing a clean install and letting Windows reformat my C drive as NTFS. I fiddled with the various property settings as Paul N. Lee suggested. However /*there is a problem*./ If I render some fractals that take a fair time, like Lee H Skinner's 6090168 (thank you for these), then unless I move the mouse every few minutes, I get a rude message from Windows saying that the pesky MD-DOS application was too slow responding to something and must be cancelled.

Re: FOTD 3_15_07

. Zoom animation into Jim Muth FOTD 3_15_07 is posted: http://www.fractal-animation.net/vid/ehz.zip 640x480, 40 sec, 6.6 MEG A strange formula. Altering the iteration count from the original 5000 to billions makes very little difference in the image. And the terminal mutantbrot never fully resolves (unless it is supposed to look like that). Altering the parameters very slightly makes little difference in the image, altering them more than that creates a blank screen. So a morph animation seems not possible. (But the zoom-in is cool anyway). Cheers JoTz .

FOTD 18-04-07 (FOTD for April 18, 2007 [7])
by Jim Muth 18 Apr '07

18 Apr '07

FOTD -- April 18, 2007 (Rating 7) Fractal visionaries and enthusiasts: The parent of today's image came about when I subtracted 0.6 parts of Z^(1.618) from 0.6 parts of Z^(-1.4142) and added straight C. This fractal can hardly be called a fractal. It is more of an oversized universe of fractals, consisting of one large and very distorted Mandeloid, a smaller less-distorted Mandeloid, and two prominent but shapeless holes. Scattered around these obvious features lie countless smaller holes of all shapes. Today's image is located in the East Valley of the largest Mandeloid. I didn't dare name today's image. I would not want to admit what it reminds me of. I did rate it at a 7 however, mostly because of the extra snap I added to the color palette. It is really a rather striking image. Perhaps the best feature of the image is its extreme speed. It calculates from the included parameter file in a mere 1 minute and 43 seconds, which is less time than it would take to go online and view the completed image on the FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> No special tricks were used in today's image. It was rendered with the inside set to number zero and the outside set to show the traditional equal-iteration bands. The slightly milder temperature of 48F 9C here at Fractal Central on Tuesday failed to compensate for the continued heavy clouds, brisk winds and occasional sprinkles of rain. The fractal cats had an unexpectedly good day despite the weather. They spent much of their time in the window, watching two doves that were hanging around the porch most all day. My day was quite peaceful for a change; I hope tomorrow can be a repeat. The next FOTD will appear here in 24 hours. Until then, take care, and don't let a stubborn fractal get you down.

FOTD 17-04-07 (Another Visitation [8])
by Jim Muth 17 Apr '07

17 Apr '07

FOTD -- April 17, 2007 (Rating 8) Fractal visionaries and enthusiasts: Today's image lies in the same stubby Seahorse Valley of the same parent fractal that produced yesterday's image. But it lies far enough away from the scene of yesterday's action to appear quite different. About 1/10th of the image consists of 'inside' stuff made visible by the 'zmag' inside fill. The rest of the image is made of good old equal-iteration bands. I named today's image "Another Visitation" because it is the second visit in as many days to the same scene. I rated it an 8 because I think it makes quite an interesting screen full. The render time of 12 minutes can be avoided by visiting the FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and viewing the image there. I am involved in writing a discussion of how I find good parameters to enter into the MandAutoCritInZ formula. To my surprise, I find that I am not sure how I find some of the good parameters. But I almost always start by setting one of the exponents to an absolute value between 1 and 2. How I find the alternate critical point to enter as the (p4) parameter is another story, which I will explain in detail in the discussion. Finding good parameters for the MandelbrotBC2 formula, which I used in today's FOTD, is a far simpler task. Either I choose an exponent between +1 and +2, or an exponent very close to a positive integer, such as today's 1.99. A value of 2.01 would have created an equally interesting parent fractal, though the fractal would have rotated in the opposite direction as the logarithmic ladder was ascended. A chilly temperature of 43F 6C, heavy clouds, strong winds and occasional showers of mixed rain and snow made conditions less than ideal for those whose business took them outdoors here in Fractal Central country on Monday. A tuna treat that was late made the day less than ideal for the fractal cats also. With the work getting lighter and the fractals getting better, my day was pretty good however. And the best part is that tomorrow looks to be a repeat. Until then, take care, and beware of scam fractals.

. That seems to be working, that fixed it! I tried the mathtolerance line but I was using the wrong numbers apparently. (maybe that would have worked for my deep zooms as well - but I sure ain't gonna go back and redo them now!) I am a man of my word - a free fractal DVD has your name on it. If interested, email me private with your shipping address. Cheers JoTz .

FOTD 16-04-07 (Alphabet Fractals [8])
by Jim Muth 16 Apr '07

16 Apr '07

FOTD -- April 16, 2007 (Rating 8) Fractal visionaries and enthusiasts: In today's image we have a glimpse of what happens when a Mandeloid with an exponent of 1.99 is calculated 10 levels up the logarithmic ladder. This exponent is so close to 2 that any midgets in it will be almost perfectly quadratic, yet it is far enough removed from 2 that the fractal it creates rotates and changes as we move up and down the log ladder. In today's case, the parent fractal is a near Mandelbrot set that has rotated about 7 degrees CCW. Most of the details of the M-set are still undisturbed, but the rotation has totally changed the northern branch of Seahorse Valley, where today's scene is located. Instead of coming to a sharp point, the valley has changed into a blunt, rounded stub filled with rampant discontinuities. I have named today's image "Alphabet Fractals" after the prominent letter'X' that dominates the frame. I rated it at an 8 because it is unusual enough to draw attention, and I rather like the contrast between the purple foreground and the brilliant green letter 'X'. And yes, there is a midget at the center of the 'X', a rather attractive midget at that. The calculation time of 3-1/3 minutes is close to average for a FOTD fractal, though I have no idea what the exact FOTD average might be. But the calculation time becomes irrelevant when the finished image is viewed on the FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> Heavy clouds, intermittent rain and an unusually chilly temperature of 43F 6C made Sunday a totally indoor day here at Fractal Central. The fractal cats took the weather in stride, since they are indoor cats every day. In my department, things continue to relax, but such pleasantly slow periods rarely last for any length of time. The next FOTD will appear almost by magic in 24 hours. Until then, take care, and think fractal thoughts.

FOTD 15-04-07 (Festive Occasion [7])
by Jim Muth 15 Apr '07

15 Apr '07

FOTD -- April 15, 2007 (Rating 7) Fractal visionaries and enthusiasts: The parent fractal of today's image came about when I subtracted 3 parts of Z^(1.1) from 3 parts of (Z). This parent fractal is quite oversized and needs an outzoom before it fits onto the screen. It looks like a Mandelbrot set rotated 180 degrees, with its East Valley pinched off. Some might see it as a lead plumb. Today's image is located in the angular, star-like debris on the southeast shoreline of the main bud of its parent. I named it "Festive Occasion" and rated it at a 7. Much of the effect is due to the colors, and when rating the image I decided to reward myself for the extra effort. It's really a rather pleasant image to look at. If it has a flaw, that flaw would have to be the rather slow calculation time of 14 minutes. But this small inconvenience can be quickly eliminated by visiting the FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and viewing the already-calculated image there. A sunny morning gave way to increasing afternoon clouds here at Fractal Central on Saturday. The high temperature of 55F 13C was not too bad, but it should be in the 60's F (around 18C) at this time of year. Fractal cats do not concern themselves with weather however. Their concern is playing and eating. The duo did a lot of both on Saturday. My day was average; more of the same is expected on Sunday. The next FOTD will appear in 24 hours. Until then, take care, and infinity is as close as your computer.

Re: Fractint Mystery
by jackoftradez＠comcast.net 14 Apr '07

. Anyone who has seen my deep zoom viddies has noticed the occasional jerk frames. I do not know what causes this, but it seems that fractint reads the PAR file wrong and scrambles the numbers for some reason. Thus with off-parameters or coordinates the image(s) are a bit distorted or off center. Now, attempting a zoom animation of Muth FOTD 3_15_07 I have encountered this again, only the error occurs in the magnification number - the first time I have seen this! I need someone to verify that I am not hallucinating. Here are PARS for 3 images in the sequence: '''''''''''''''''''''''''''''''''''''''''''START PAR'''''''''''''''''''''''''''''''''''''''''''''''''''''''''' 782.0000 { ; reset=2004 type=formula formulafile=allinone.frm formulaname=mandelbrotbc2 passes=1 center-mag=-0.63982851388294900/+1.17265143805666000/1.35148269130032e+12 params=1.5/0/85/0 float=y maxiter=5000 inside=0 periodicity=10 } 783.0000 { ; reset=2004 type=formula formulafile=allinone.frm formulaname=mandelbrotbc2 passes=1 center-mag=-0.63982851388294900/+1.17265143805666000/1.37763961568162e+12 params=1.5/0/85/0 float=y maxiter=5000 inside=0 periodicity=10 } 784.0000 { ; reset=2004 type=formula formulafile=allinone.frm formulaname=mandelbrotbc2 passes=1 center-mag=-0.63982851388294900/+1.17265143805666000/1.40426842987625e+12 params=1.5/0/85/0 float=y maxiter=5000 inside=0 periodicity=10 } frm:MandelbrotBC2 { ; by several Fractint users e=p1, a=imag(p2)+100, p=real(p2)+PI q=2*PI*floor(p/(2*PI)), r=real(p2)-q Z=C=Pixel: Z=log(Z) IF(imag(Z) > r) Z=Z+flip(2*PI) ENDIF Z=exp(e*(Z+flip(q)))+C |Z| < a } ''''''''''''''''''''''''''''''''END PAR'''''''''''''''''''''''''''''''''''''' You clearly see the mag factors are 1.35e+12, 1.37e+12, and 1.40e+12 respectively. The first and last render correctly, but the middle one ends up with a mag factor of 6.88e11 ! Why is this and where does the number come from? It is totally reproduceable too! You dont have to render the entire image (they take awhile). Just a couple lines then hit TAB key to see the numbers. A clue might be that this only occurs in the last third of the sequence - beyond e12. There are so many messed up frames an otherwize awesome zoom is not now good for posting! Whoever solves the mystery gets a free DVD! Cheers JoTz .

FOTD 14-04-07 (Merging Dry Valleys [7])
by Jim Muth 14 Apr '07

14 Apr '07

FOTD -- April 14, 2007 (Rating 7) Fractal visionaries and enthusiasts: Today's image mixes Z^(1.95) with Z^(2.05) before adding C, making the overall power an average of 2. The parent fractal created by this formula resembles a perturbed Mandelbrot set. And today's scene is located on the edge of what appears to be the remains of Seahorse Valley. The things in this valley are like nothing found in the real Seahorse Valley however. The peanut-shaped hole at the center of the image lies at the center of what I call a dry valley. Dry valleys are areas that start out with 2-way symmetry, giving the impression that a quadratic midget lies at the center, but they come to dead ends. Today's dry valley is unusual in that a peanut-shaped hole lies at its center. The peanut shape is actually two circular holes which have partially merged. The edge of the hole is actually a discontinuity, making a greater maxiter useless. No more detail can be found inside the peanut hole regardless of how high the maxiter is raised. I named the image "Merging Dry Valley", which is a full descrip- tion of what we are looking at. I rated it at an above-average 7. Unfortunately, the calculation time is a rather slow 14-1/2 minutes. But this wait may be bypassed by visiting the FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and viewing the pre-rendered image there. In my collection I have 6 MandelbrotMix type formulas. 'MandelbrotMix1' has long been discarded. It simply combines 2 powers of Z and always initializes Z to zero. It makes no effort to find a critical starting point. 'MandelbrotMix2' appears to be identical to the 'MandAutoCritInZ', which I just wrote. It automatically initializes Z to a critical value and allows initial Z to be manually reset to a second critical value. If I had checked this formula carefully, I would have had no reason to write the 'MandAutoCritInZ' formula. 'MandelbrotMix3' mixes 4 powers of Z and allows Z to be initialized manually to a critical value that has been determined by calculation. 'MandelbrotMix3a' is the same as 'MandelbrotMix3' with the added ability to change the escape radius. 'MandelbrotMix4' is the workhorse formula, which automatically calculates a critical value of the entered formula and initializes Z to this value. 'MandAutoCritInZ', the newest formula, takes the 'MandelbrotMix4' formula and adds the ability to manually initialize Z to a second critical point, which must be calculated separately. I also have a 'JuliaMix1' formula, which calculates the Julia sets of the fractals crated by the MandelbrotMix family. This formula can draw some very attractive fractals. It has been grossly under-used. And finally, there is a formula named 'ParabolicMix3', which graphically and rather laboriously determines the critical values of entered formulas. Heavy clouds, blustery winds, occasional sprinkles of cold rain and a temperature of 43F 6C kept spring at bay here at Fractal Central on Friday. The two fractal cats sat on their shelf by the sunniest window in vain. They never got the warm sun they were waiting for. They consoled themselves with an extra treat of tuna in the evening. My day was notably average. Saturday will likely be the same. The next FOTD will appear in 24 hours. Until then, take care, and walk with your head in the stars and your feet on a fractal.
