Today's image pictures one of these fractal trees. I originally had named the picture "Tree", but since the tree in the picture is but one of an infinity, I finally decided on the name "Fractal Forest". The image is almost, but not quite, part of a Julia set of the (-Z)^1.618034+C Julibrot figure. It is not a Julia set because the direction of the slice is rotated 1.8 degrees from the Julia direction. This slight rotation makes little difference in the overall appearance of the image, though it does give the 'tree' a more stylized appearance. This type of image is quite common in the world of fractals, and it is closely connected to a rocky-landscape type of image that I occasionally investigate. In a day or so, I'll give an example of the rocky landscape hiding in today's tree-like image. I used John Goering's formula to draw the image and do the rotating. This formula can draw more orientations within the Julibrot than any other I know of, though there are still some directions that it cannot reach. The attached parameter file renders in a couple minutes, which is fast enough for all but the busiest fractaliers. For those busy fractaliers, the GIF image will soon be posted on Paul's web site at: and on Scott's site at: The fractal weather today was near-perfect, with blue skies, puffy clouds, and a happy-cat temperature of 82F (28C). Unfortunately, the cats were so happy that they spent most of the day sleeping. As for me, I'll have to spend most of the day working. And the day is just starting. But I shall return with a new FOTD in 24 hours or so. Until that glorious moment arrives, take care, and enjoy the day.

A while back I wanted a way to visual the many, many .MAP files I've accumulated for FractInt, so I wrote a utility to create small .GIF files (256 x 100) displaying the .MAP. Did I miss an existing tool (seems kind of a no-brainer, so I can't believe I'm the first)? Is there any interest? I can offer: a unix-based version that should compile under any decent C compiler, or a Windows version for VC++ v6. NOTE: both use the gd 1.3 library that is no longer supported by its author (that GIF legal mess). I couldn't *fully*legally* make the images I've made available, at least not as .GIFs. (Also, the Windows version is a console program.) So,... if there does seem to be any interest, I might put all the common .MAP images up as .JPG and/or .PNGs. It'd be fun, again assuming anyone wants this, to have an image generator that you could upload a new .MAP file to and get back an image. But again, I don't know if anyone cares. - -- |_ CJSonnack _____________| How's my programming? | |_ http://www.Sonnack.com/ ___________________| Call: 1-800-DEV-NULL | |_____________________________________________|_______________________| - -------------------------------------------------------------- Thanks for using Fractint, The Fractals and Fractint Discussion List Post Message: fractint@lists.xmission.com Get Commands: majordomo@lists.xmission.com "help" Administrator: twegner@fractint.org Unsubscribe: majordomo@lists.xmission.com "unsubscribe fractint" ------------------------------ Date: Sat, 14 Jul 2001 14:16:51 +1200 From: "Morgan L.

For each point (X,Y,Z) in space, the texture specifies a fourth number which which (via the colourmap) gives the colour of that point. To come at it from the other direction. If you're trying to reconstruct the texture used on a given set of points (the surface of a sphere, let's say) you need to know more than just the three spatial coordinates of each point, you need to know where they lie along the colourmap dimension as well. Just as you need more than just latitude and longitude to locate an aircraft, just as Newtonian mechanics uses three numbers for position and another three for momentum, and just as you need three numbers to position and another three to orient an object in space unless it's circularly symmetric along one or more axes.

But instead of viewing the scene from close to the Julia direction, today we view it from the Mandelbrot direction. I named the picture "Monolith Monsters" after one of my favorite old sci-fi movies. I rated it a perfectly average 5. What once was a figure-eight edged with tree-like shapes has now become a valley edged with monolithic rocks -- a scene on an alien planet if you wish. The alien rocks, which once formed the crown of a tree, decrease in size as they fade into the distance, and the alien sky above, not quite like earth's, has an unearthly rusty tinge near the horizon. I would estimate the average temperature on this planet, which is circling an orange class-K star, to be -40F, which is also - -40C. The atmospheric pressure appears to be about 250mb, 1/4 that of earth's. But unfortunately, there is no water, and life never had a chance to get started. The curious rocks have obviously been formed by volcanism, though the chemical composition that would crystallize into such strange shapes is yet to be determined. Several deep fault lines extend diagonally through the scene, and even a short way into the sky. I'll not attempt to explain how an atmosphere can support fault lines, but the atmospheric discontinuities *are* there. Finally, the trip to this exotic place takes only 2-1/2 minutes, via the parameter-file spaceship. For those without a ticket, the scene will soon be showing at the following web sites: and: The fractal weather today was once again perfect, with blue skies, puffy clouds, (which are also possible to create with fractals), and a very earth-like temperature of 82F (28C). The fractal cats, who really have little interest in fractals, spent most of the day on the porch, taking it easy. I've been taking it a little too easy for several days, and I now find myself with a yard of grass in need of a trimming. Oh well, there's only one way I know to get the job done -- and that's to get started. So until next time, take care, and do fractals exist on other planets?

By guess is that they're cached as files for each request, to cut down on blob queries to the database. Morgan L.

The question now becomes whether a fractal really exists if no intelligent life is there to be aware of it. Perhaps a better way of stating the question is to ask whether fractals existed on earth 2000 years ago, before we knew of them. And this is simply another form of the old philo- sophical question of whether we create reality by considering certain things of which we are aware to be real, or whether the things would be real even if no intelligent life existed to be aware of them and declare them real. Today's modest offering most certainly is real. (I think.) It is an example of a very common fractal feature I call a 'dry lake'. All too often while tracking down a midget, I come upon features of a class I call 'dry lakes'. One of these dry lakes exists at the exact center of today's image, and is the reason I named the picture "Dry Lake". A dry lake is surrounded by the symmetrical type of features that point the way to a midget, but before the midget is reached, the basin bottoms out in a saddle-shaped surface. These saddle surfaces indicate a failed search, and as soon as I see one, I usually turn away to search elsewhere. I consider these dry lakes to be near misses. A midget does exist nearby in the surrounding Julibrot, but the slice on the screen misses the midget by a narrow margin. Still, if the slice comes close enough to the actual midget, some of these dry lakes display nearly perfect surrounding features. In these cases, the presence or absence of a central midget makes little difference. But I sometimes wonder whether a program designed to automatically track down midgets would be fooled by these dry lakes. Today's image, which misses the midget by a rather wide margin, shows a relatively imperfect dry lake, with symmetry that is unbalanced and does not go beyond the stage of 2. Because of its imperfection, I rated the image a below-average 3. With a render time of 15 minutes, the parameter file tries one's patience. A download of the GIF image is the way to see today's FOTD. That download will soon be available at: and at: The fractal weather today here at Fractal Central may safely be passed over. But for those who have an interest in such unimportant things, it was another perfect day, with blue skies and a temperature of 84F (29C). The cats were happy all day. It's now time to do other things. So until next time, take care, and we have the fractal saddle, all we need is the fractal horse.

Forno" Subject: (fractint) Another use for fractint Some time ago, I discovered another practical use for fractint. I created a batch file f.bat which simply called fractint.The f.bat file was under the /bat directory, which I included in the path. Then, when some program under DOS lets the screen in an abnormal state, for example with different colors or letter size, I simply type f and when fractint appears I press Esc. This easily returns the screen to its normal state. - -------------------------------------------------------------- Thanks for using Fractint, The Fractals and Fractint Discussion List Post Message: fractint@lists.xmission.com Get Commands: majordomo@lists.xmission.com "help" Administrator: twegner@fractint.org Unsubscribe: majordomo@lists.xmission.com "unsubscribe fractint" ------------------------------ Date: Mon, 16 Jul 2001 11:05:11 -0400 (EDT) From: Jim Muth Subject: (fractint) C-FOTD 16-07-01 (Corona [7]) Classic FOTD -- July 16, 2001 (Rating 7) Fractal visionaries and enthusiasts: With today's image, we rise out of yesterday's abyss. Today's image resembles a something -- I am not sure what -- but while studying it, searching for a name, I had the impression of the sun during a total eclipse, with the arcing colors surrounding the central circle being the coronal loops. True, the central circle with its horizontal stripes bears little resemblance to the black disk of the new moon, but with a bit of imagination, the resemblance to the eclipsed sun with its coronal streamers is there. Yes, I have noticed the area at the bottom of the striped circle, which looks suspiciously like a midget. Since July is quadratic midgetless month, this object, if it is in fact a midget, has no right to be there. But it is so unobtrusive that even if it is a midget, it does not violate my pledge to have no more midgets in July. Perhaps I'll investigate this area after the end of this month, when quadratic midgets will once again be permissible. The formula behind today's image is number 13 in my series of 14 MandNewt formulae. Some of the image is outside material, some is inside colored by the bof60 option, and some is open inside, which should be colored by the inside fill, but for some reason is not. Turning on the logmap adds color to the black areas of today's image, but I like it better the way it is. After a short period of pondering, I named today's FOTD "Corona", and rated it at a 7. And seven minutes are required to render the image from the parameter file. The image will also soon be available in GIF form on the Web at: and at: The fractal weather today was once again perfect, with blue skies, puffy white clouds, and a cat-pleasing, wading-pool- splashing temperature of 86F (30C). Unfortunately, we've now come to the end of another FOTD, but additional FOTD's are lined up into the indefinite future, and the next one will appear within 24 hours. Until that golden moment arrives, take care, and fractals are as real as we consider them to be.
