FOTD 09-03-02 (Deuce and a Half [5])
by JimMuth＠aol.com 09 Mar '02

09 Mar '02

FOTD -- March 09, 2002 (Rating 5) Fractal visionaries and enthusiasts: There's a lot of emerald in today's image, and I was first going to give it a name describing something emerald. But before finding the proper emerald name I decided to name the image after the exponent of Z, which is 2-1/2. It's an image of a midget in a valley of its parent fractal, which is located 31.8 levels up the abstract logarithmic spiral. Although the Z^2.5+C Mandeloid comes in many shapes, the shape of today's midget is one of the most frequently seen. The broken spiral arms are an inescapable feature of images with fractional exponents of Z. In fact, the BC in the name of the generating formula stands for 'branch cuts', one of the names by which these discontinuities are known. After a few moments of thought I found the name "Deuce and a Half". A few more moments passed before I decided to rate the image at a 5. The render time of 4 minutes is not too much to spend on a merely average image, but those who would rather spend even less time may find the image posted at Paul's web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and at Scott's site at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The weather Friday was quite spring-like, which made the fractal cats quite happy. The temperature of 70F 21C and warm sun brought out the best in them, giving them nothing more to do than lie on the porch and sleep the afternoon away. I however have much to do -- a little real work and quite a bit of work on the upcoming FOTD CD. So until next time, take care and be patient. The FOTD we know and love will return on a new and improved daily basis when the CD is ready in a few months.

CPU Speed
by Lee Skinner 09 Mar '02

09 Mar '02

A few weeks ago, I was mentioning that I was considering a CPU upgrade. I have now done that, and I wanted to mention the following single benchmark that I made. I went from a 233Mh Pentium 1 to a 2Gh Pentium 4. I used DOS 4DOS under DOS 6.22 on both machines. (Sorry, Rich!) I was told that the P4 emulates 16-bit applications slower than the original Pentium does, so I didn't know what increase in speed I'd get. There was an 858% increase in CPU processor speed for the two machines, but what would be the increase in Fractint calculation speed? I ran an arbitrary precision mandelbrot on both: Pentium 233Mh: 0:37:44.42 (2264.42 sec) Pentium 4 2Gh: 0:06:04.33 ( 364.33 sec) or a 621.53% increase speed for the Fractint CPU time. The ratio of the Fractint speed increase to the CPU speed increase is .7244, the penalty for running a 16-bit application on the P4. This ratio is higher than I expected, and I do get more than a 6-fold increase in Fractint calculation speed. But what if I had upgraded to an AMD Athlon? I would like to know what this ratio would have been for that! Lee Skinner

>> Instead of changing back to text mode, it changes to some mode that my monitor can't even display (it just complains that the signal is out of scan range). << Interesting. That happened to me (just once) yesterday - I had to reboot by pressing the physical button! I wonder if that is an intermittant problem with the latest developer's patch of Fractint! (It happened to me when I hit the tab key to go to the tab screen - it's never happened before, and I've had the video card for years. It may be related to the high CPU speed we're both using. A message box appeared saying "Out of Scan Range" and the machine was dead. Is that message coming from Fractint, Jonathan?

Jim, >> I am also watching with interest the current thread on the Fractint list about CPU speed, since I plan on soon purchasing a new machine and want to be sure I choose the one that works the best and fastest with Fractint, and not one that can't even display the VESA video modes. << I also kept my old Millenium video card which runs 1600x1200 VESA mode. I can't play all these new 3D video games, but I can still run Fractint very fast! I also didn't post the benchmark here on the list because it measures the time to compute the 309th line of a very slow and deep arbitary-precision mandelbrot that took several hundred hours to get to that line. I sent the benchmark image to Pedro who will run it on an AMD Athlon and he will post the results tomorrow. (Running it in batch mode with savetime=-1 will time the line regardless of how long it takes, as savetime only saves at end of the row - a very handy feature for setting the showdot at the beginning of a line and on the next batch run - timing a line.)

FOTD 06-03-02 (Somber Center [6])
by JimMuth＠aol.com 06 Mar '02

06 Mar '02

FOTD -- March 06, 2002 (Rating 6) Fractal visionaries and enthusiasts: The FOTD CD preparation is in full swing, the main hold-up being the time required to re-render the old images, most of which are SF5 and SF7, at the SF6 800x600x256 resolution. I am also locating hundreds of my very early fractal efforts, which were created with several fractal generating programs and need to be converted to GIF format for inclusion on the CD. These very early images, some from before 1990, are of variable quality, but they do show the route I took on the way to the present stage of my fractal development. I am also watching with interest the current thread on the Fractint list about CPU speed, since I plan on soon purchasing a new machine and want to be sure I choose the one that works the best and fastest with Fractint, and not one that can't even display the VESA video modes. Today's fractal diversion is a quick trip to the Z^3+C Mandeloid for a quick, (if 18 minutes can be considered quick,) glance at a cubic midget. I named the image "Somber Center" because the brilliant and lively detail in the outer areas grows ever more dull and somber as the midget is approached. The completed GIF image will be available in a few minutes on Paul's web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and Scott's site at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The fractal weather Tuesday here at Fractal Central was sunny but quite cold. Starting at 11F -12C, the temperature rose to 38F 3C by the afternoon, which was not nearly warm enough for the sensitive ears of the fractal cats, who demanded and got two treats of consolation tuna. As for me, I've got a couple customers demanding their jobs, which I had better get started on if I hope to finish by this afternoon. And of course, there's the work on the FOTD CD always waiting in the wings when I run out of other things to do. Until next time, take care, and a cube is sometimes better than a square.

FOTD 03-03-02 (Second Chance-01 [6])

06 Mar '02

FOTD -- March 03, 2002 (Rating 6) Fractal visionaries and enthusiasts: Today's image, which rates a 6, is a zoom into one of my old FOTD images. This is why I named it "Second Chance-01". And yes, the '01' part does imply that I will be featuring many more zooms into old FOTD's. Those old images each hold infinities of scenes that were missed the first time I passed that way. It's time to give them a second chance at life. Today's image is found in one of the images that appeared in December of 1998. At the moment I forget which one. The formula is the direct precursor of my overworked MandelbrotMix4 formula. And the time required to see the second chance is 23 minutes, for those who choose to run the parameter file. It is far less when the GIF file of the image is downloaded from: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The fractal weather Saturday was cloudy, with rain beginning in the afternoon. The cats were quite unhappy. The rain is still falling today, so the cats will once again be unhappy. A rainy day however is perfect for gathering and formatting old FOTD's. And I've still got an impressive amount of gathering to do. So until next time in a few days, take care, and start anticipating.

FOTD 22-02-02 (2-of-4 [4])
by Jim Muth 01 Mar '02

01 Mar '02

FOTD -- February 22, 2002 (Rating 4) Fractal visionaries and enthusiasts: The CD is progressing on schedule, with (so far) only minor problems. If things continue this way, the disk will be ready by this Summer, Winter, wet season, or dry season, depending on the climate where this letter is being read I named today's image 2-of-4, not because it reminds me of a Star-Trek episode, but because it is the second FOTD created with my new experimental formula, which mixes four powers of Z. The formula has been changed since I used it for the most recent FOTD, but the parameter files that were written using the first version of the formula will also work with the present version, (if the function is set to <ident>), so I did not change the formula name. Today's image rates only a 4. But this does not make the formula a failure. Rather, it is a sign that I have not yet become familiar with the things that might be possible when four powers of Z, some negative, some positive, are combined in a single iteration. To be honest, today's image resembles many images that I have passed over while using the M-Mix4 formula. I suspect that adding ever more powers of Z in a single iteration will soon result in diminishing returns, much as raising the exponent does in a formula such as Z^100+C. But I'll give my new formula a fair trial before consigning it to the graveyard of forgotten formulas. (Formulae for the over-educated.) The six-minute render time is bearable. Downloading the completed image is even more bearable. And the image can be downloaded from Paul's web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from Scott's site at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The fractal weather Thursday was ideal for man and cats alike -- warm sun, mild breezes, and a spring-like temperature of 66F 19C. Now that the midday sun has cleared the holly trees, the porch was ideal for Thomas and Tippy, who passed the afternoon there, sunning themselves and watching the robins. As for me, it's back to work and back to the FOTD CD, which is now 14 percent completed. Until next FOTD, take care, and things can only get better.
