FOTD 09-02-02 (Mandelbrot-02 [5])

FOTD -- February 09, 2002 (Rating 5) Fractal visionaries and enthusiasts: The job of preparing the FOTD CD grows ever more formidable. The current difficulties are caused by the total lack of uniformity of the early FOTD's. Due to bad line breaks, etc., many of the parameter files will no longer run, and need to be re-created from the original GIF images. Also, the size of the saved images is anything I was in the mood for at the time. The off-size images need to be re-rendered in the SF6 (800x600x256) format, which will be the standard size of the images on the CD. Luckily, when I realized that the FOTD would become a major project, I settled into a uniform style, but I still have a year or so of haphazard format to struggle through before I reach the easy part of the job. I'll keep everyone updated on the FOTD CD progress. Today we have another simple scene -- a midget deep in a spiral in the north branch of Scepter Valley of the Mandelbrot set. Due to the cursory coloring, the image rates an average 5. A better job of coloring would raise the rating to a 7. The render time of 6 minutes is a bit much to ask for a merely average image. The more efficient way to view the scene is to let Paul and Scott render the image and pick it up from one of their web sites. Paul's site is at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and Scott's is at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The fractal weather Friday pleased the cats, who spent several hours on the porch, waiting for the sun to clear the holly trees and bathe them in solar radiance. Unfortunately, it will be a couple weeks before the sun angle grows high enough to rise above the trees and reach the porch. The temperature of 56F 13C made up for the lack of sun however. It's now time to get back on a bit of regular work, and when that is finished, to tackle the FOTD CD. Until next time, which will come in 2 or 3 days, take care, and see you then.

FOTD 07-02-02 (Mandelbrot-01 [5])
by JimMuth＠aol.com 07 Feb '02

07 Feb '02

FOTD -- February 07, 2002 (Rating 5) Fractal visionaries and enthusiasts: Because the FOTD CD will be more work than I had originally estimated, I have decided to continue posting some new FOTD's, though not at the one-per-day rate. I will try however to post two or three new FOTD's per week. My spare time will be divided between working on the CD and posting new FOTD's. I will concentrate on the classic Mandelbrot set for my new FOTD images, since the built-in Mandelbrot formula is far faster than the type=formula fractals, and I will need all the time I can muster for the CD. Also, the Mandelbrot set is the world's richest fractal. The extra effort on the CD will be devoted to rewriting the many passages whose awkwardness has become obvious only long after I wrote them. And since I will need to sell the CD, it will need to have sufficient new material to make the product worth the yet-undetermined price. Luckily, I have ample never-posted material ready to be included. Of course, pictures of myself, Fractal Central, and the fractal cats will be included. It is too early to estimate when the CD will be ready, but I'll keep those on the lists posted. Today's image is a scene in a very high iteration spiral in a remote valley of the Mandelbrot set. It rates only an average 5, and has been given a catalog number rather than a name. The render time of 16 minutes can be avoided by downloading the completed GIF image 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 Wednesday here at Fractal Central was nondescript. In response, the fractal cats had a nondescript day. The discomfort of the lack of sun was mitigated by the above-average temperature of 50F 10C, leaving the dynamic duo in a state of indecision. They didn't decide until I offered them a dish of tuna, at which time they decided to eat. Well, I've got to get busy on that FOTD CD, among other things. Until the next Mandelbrot FOTD, which will appear in a few days, take care, and see you soon.

Some development suggestions for L-systems
by Tony (Anthony) Hanmer 06 Feb '02

06 Feb '02

I have been familiarising myself with Fractint's L-system types for about 3 years now, and while I still have a long way to go, I have some ideas about how to further develop this part of the programme. It isn't, perhaps, used nearly as much as some other parts, but could still stand some modifications, which might attract a new set of users. The first improvement would be to allow for colour *vector* output, e.g. dxf or ai, instead of only bitmap output. L-systems are linear-based, not pixel-based. (I have a mutant version of Fractint sent to me by one of Fractint's developers which allows for dxf output, but without colours. This has enabled me to render L-systems as large as 1 GB, which fortunately compress to about 4% of their size when imported into CorelDraw and saved there!) A probability function would allow for more realistic-looking trees and other living forms to be emulated. For example, the option of setting a probability that any given part of the L-system string would occur, be it an angle change, size change or whatever. This seems to be a feature of some other L-system generators I have read about in books on fractals. I suppose that there would have to also be some way of ensuring that every somewhat "randomly" generated L-system could be produced more than once, e.g. by recording the actual variables used in each case of allowing the probability function. if...then, etc. could also be incorporated. If the line(s) resulting from iteration x reach or surpass an angle of y in relation to the horizontal or starting angle, do z: introduce an alternate text string command. If the total number of line segments resulting from iteration x reaches number y, do z; etc. A final modification, which is rather specialist so far but again which could enlarge the group of L-system uses, would be to allow *animations*. Currently, by using d instead of f, and setting angles instead of using Angle x, angles can be varied to the limits of Fractint's precision, allowing one L-system to mutate into another. The start and end parameters could be set, along with the intervening number of pieces to produce, and then the programme allowed to generate the whole set of pieces, which collected together would form a smooth animation from starting form to finishing. Actually writing a separate L-system for each piece would not then be necessary. I have many pairs of L-systems which would benefit from this proceedure. (IFS types and, I suppose, most fractal types could also be treated similarly. There are already a number of fractal animators out there; but can any of them handle L-systems?)

FOTD 04-02-02 (A Fractal Hiatus [4])
by JimMuth＠aol.com 04 Feb '02

04 Feb '02

FOTD -- February 04, 2002 (Rating 4) Fractal visionaries and enthusiasts: Today's simple image is named "A Fractal Hiatus". I gave it this name because it is the last FOTD that I will be able to post until I finish the job of organizing and producing that long-talked-about FOTD CD. There is simply too much work involved to efficiently handle both the ongoing FOTD and the FOTD CD. I have no idea how long it will take to finish the CD, but if no new problems come up, I should have it finished in a few weeks. When the CD is ready, I will resume the ongoing daily FOTD. In the meantime, I will continue reading the lists and will post an occasional comment on the progress of the CD, or whatever comes to mind. But right now, I've got a pile of serious work in front of me, so I'd best get started. The parameter file of today's image runs in 7 minutes on my P200 machine. And the GIF file is available on Scott's web site at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> Paul's whereabouts remains a mystery. With a temperature of 43F 6C, the Sunday weather here at Fractal Central was normal winter fare, which, despite the sun, did not please the cats. Until next FOTD, take care, and see you soon.

FOTD -- February 03, 2002 (Rating 3) Fractal visionaries and enthusiasts: Gathering and organizing the material for the upcoming FOTD CD is proving to be a more difficult task than expected, which I suppose is not unexpected. I present today's weak effort as a little scene I found with almost no effort. There's not much in it to speak of, so I'll let the image speak for itself. As always, the GIF image can be downloaded from Scott's web site at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The weather Saturday was cold and blustery. The cats were happy to remain indoors -- 39F 4C is far too cold a temperature for such intrepid felines. As for me -- I've got tons of work to do on that CD. The new FOTD's might appear at somewhat irregular intervals while I'm busy, but I'll be here every day reading the lists, which is not much of a task. Hopefully, the next FOTD will appear in 24 hours. If not, it won't be too far off.
