Hello Gerald et al: I like your solution. It is cleaner then mine, but I am having trouble with implementing it. I am not sure how to use erase 'F= ' recursively. I do not have a method in my turtle set for doing this. I am also not sure about how to translate this into a recursive method using Java and turtles.(If this is the wrong place to be asking this question, then just let me know. I am new ot the group, and I am not sure what constitutes an on topic or off topic post) Here is what I hacked out. It works but in kind of a 'wonky' way. So P becomes my method call. R and Q are executed after the respective method calls. angle 4 axiom P P = FPRPQPF R =+F-F Q=-F+F private void drawSkyline(Turtle t1, int itr, double distance) { if(itr == 0) { return; } drawSkyline(t1,itr-1,distance/1.5); t1.turn(90); t1.move(distance); t1.turn(-90); t1.move(distance/3); drawSkyline(t1,itr-1,distance/1.5); t1.turn(-90); t1.move(distance); t1.turn(90); t1.move(distance/3); drawSkyline(t1,itr-1,distance/1.5); //t1.move(distance); } Thanks j.

FOTD 30-11-05 (Deep in the Jungle [6])
by Jim Muth 30 Nov '05

30 Nov '05

FOTD -- November 30, 2005 (Rating 6) Fractal visionaries and enthusiasts: Today's image is an evaporated one. It once was there but now is gone; it leaves its ghost to carry on. The original image, which consisted of the usual inside-outside stuff, was created by combining two negative exponents of Z, (-1.5) and (-8.5). The image was then evaporated by raising the bailout radius to one-googol, which is quite a large number. When the original image vanished, nothing was left but a blank screen consisting entirely of 'inside' stuff. The situation looked hopeless, but hidden in the inside stuff was the ghost of the original image, and it took only the ghost-hunting 'bof61' inside fill to manifest the spirit. The resulting image reminds me of a scene in a jungle. I named it "Deep in the Jungle". Since I have done several similar images in the past, I could rate it no higher than a 6. I am a strict rating master. The render time of 1-3/4 minutes means that no one will succumb to boredom while waiting for the included parameter file to run. At the same time, those with computers over-qualified for Frac- tint can find the finished image posted on the FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> The rain held off long enough on Tuesday here at Fractal Central for the cats to enjoy the unusually warm temperatures in the mid 60's Fahrenheit (for the backward USA), around 18 Celsius (for the rest of the world). They lurked in the holly patch several hours, and by the time the rain arrived they were about ready to come inside on their own. The next FOTD will appear in 24 hours. Until then, take care, and if you can find a bald eagle, walk with it. If not, walk with an eagle with feathers.

FOTD 29-11-05 (Get the Point [7])
by Jim Muth 29 Nov '05

29 Nov '05

FOTD -- November 29, 2005 (Rating 7) Fractal visionaries and enthusiasts: Today's image pictures part of the empty inside of a Julia set of the Z^(1.009)+C Mandeloid as it appears 109 levels up the infinite logarithmic spiral. This empty inside was brought to life not by a bolt of lightning, as the Frankenstein monster was, but by the bof60 inside fill. So far, so good. But something is wrong. The image has no 'bof60' feeling to it. It consists of a cloud of floating daggers arranged into a large broken spiral, with the bright blue background barely showing through. Normally, the bof60 inside fill produces a scene with circular bubbles, much like the 'fmod' fill does. It is this unexpected nature of the image that adds the interest which raises the rating to a 7. Also interesting is the fact that the exponent of Z, at a value of 1.009, is so close to unity, a value that does not make fractals. Curiously enough, in this almost-linear range, most of the action is in the inside parts of the fractals. The con- ventional inside-outside fractals tend to resemble rather boring mis-shaped eggs. The coloring appears quite full, but actually only 20 or so different colors appear in the scene. Luckily, 20 colors are all that is needed to "Get the Point", which BTW is what I named today's image. The image is just the center part of the whole inside of the parent fractal. For an additional surprise do an outzoom and check the entire parent, which is nothing like what one would normally expect. Today's FOTD render time of 8 minutes borders on slowness. But the finished image may be downloaded from the FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> which will eliminate the task of rendering. The partly cloudy skies and mild temperatures of 68F 20C on Monday here at Fractal Central were spoiled by occasional light sprinkles and wet grass, which limited the cats' outdoor adven- ture time to under 30 minutes. My outdoor time was limited by the work that needed to be done after the holiday. The next FOTD will appear in 24 hours. Until then, take care, and the FOTD images will one day vanish, but the fractals themselves are eternal.

FYI: Lee Skinner posted about 17 par files a few issues ago. He said some would take a while to render. He was right. They have been cruising 3 days now in auto-mode on my P2-300 and still not done! Some of them look real good. I will post the completed pix/pars on my server in a few days when done if NY1 is interested. Hey - NY1 know when fractint 1.0 was first released? Gotta be getting near the 20th anniversary soon!? Fear God. Nothing else. JoTz

Disk video/ram
by David Fisher 29 Nov '05

29 Nov '05

I have what is probably a minor problem with writing and saving to "Disk video/ram". Briefly, I edited the config file and added a line for another resolution. Works fine for almost all my saves, but there are six fractals (out of 293 processed do far) that will not save in the new mode. Can anybody tell me why?, and what I can do to fix this? Just for general info: The newly added mode is at 2560x2048. The next resolution down at 2048x1536 works on all the pictures, 'cause I've tried both. Is the problem with the cache size? Can this be adjusted? Any help, information, etc, would be greatly appreciated. Even a negative response is good, if the problem is intrinsic and I'm wasting my time trying to fix what can not be fixed. David M Fisher

FOTD -- November 28, 2005 (Rating 6) Fractal visionaries and enthusiasts: The string of low-order Julia sets is unintentionally turning into a kind of running theme. Today's image pictures a Julia set of the Z^(1.1)+C Mandeloid calculated 109 levels up the spiral. Despite the unusually intricate features, the image was rendered in the traditional way, with the inside, (of which none is visible), a flat black and the outside set to 'iter'. I named the image "Glorious", letting the viewer decide what is the glorious aspect of it. The rating of a 6 indicates that I consider the image just the slightest bit above average. The render time of under 2 minutes should try no one's patience, unless they are using a Fractint-challenged computer, that is, in which case they will need to download the pre-rendered image from the FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> Alto-stratus clouds moved in on Sunday here at Fractal Central, but the temperature reached a relatively balmy 52F 11C, which was mild enough to give the fractal cats the time in the holly patch they needed to keep them happy. Tippy actually climbed half way up a holly tree after a bird, which as expected, flew away long before he reached it. A minor treat of tuna in the evening kept the duo happy. My day was uneventful. To some this might seem a bit dull, but actually, I consider myself lucky to have escaped being dragged to a holiday dinner. The next glorious or not so glorious FOTD will appear in 24 hours. Until then, take care, and after wondering, be sure to recognize the answer when you find it.

Rendered at higher res - 800x600 also. At 6.5 meg, this is only for serious fractal explorers. Grayscale is hard enuf to see as it is - you need maximum detail in the viddie / pix. Compressing to MPEG4 (WMV) format causes unacceptable loss in detail and resolution, even if the file is much smaller.
