FOTD 20-02-10 (Sesquioxidizing [4])
FOTD -- February 20, 2010 (4) Fractal visionaries and enthusiasts: NEW FORMULA ALERT! Today's formula is new. Actually, this new 'SliceJulibrot5' formula is almost exactly the same as the old "SliceJulibrot4' formula. Only the sign of iter- ated 'Z' is changed. The new formula has potential, but due to lack of time, I was unable to do much experimenting with it. I did find a minor scene in a near-Julia-set of the East Valley area of a minibrot on one of the main stems of the (-Z)^(2.5)+C Mandeloid. Unfortunately, I had no time to do much with the image, which I post here for some mild interest and amusement. Searching the image, I could find nothing in it worth more than a rating of a miserable 4. To add to the insult, the calcula- tion time of over 8 minutes is more than the image is worth. The name "Sesquioxidizing" has something to do with chemistry and little to do with today's image. I chose it because it is the word that scored the most points in Scrabble history for a single word -- around 1050 points. Those who enjoy less-than-mediocre fractals may view today's failure by running the included parameter file or by surfing out to the FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> A few clouds Friday morning here at Fractal Central cleared out by noon, leading to a pleasant afternoon with lots of sun and a temperature of 43F 6C. The fractal cats thoroughly enjoyed the afternoon sun on their shelf in the southwest window. As stated above, my day was rather hectic. The next FOTD will be posted in all of 24 hours, that is unless FL gets the urge to visit and explore a local flea market or antique emporium or something. Until whenever, take care, and why do women who claim to dislike all the violence in the world, read so many murder mysteries?

Subject-Was: [Fractint] FOTD 20-02-10 (Sesquioxidizing) I do not remember the period during which Jim posted fractals from hard-coded types. I remember that it was some of his best work. I made a post about one that was clearly a white noise jenerator of some kind. Your initialization code typically very complicated, Jim. I would like to see more creativity in your loops. My initialization code is the same for most of my formulas: z=fn1(pixel), c=fn2(pixel), s=P1: Parameters in my fractals are typically integers. I regard MandelBroh as public domain in that respect: MandelBroh { ; Anglicized spelling. Recommends sticky functions. z=fn1(pixel) +P2, c=fn2(pixel) +P3: z=z^real(P1) +c |z| <= imag(P1) } Last time I checked, the default functions were sin, and every time I changed fractal type, they were RESET to "sin". I would like to see the default functions changed to "ident", and the function reset operation deleted. That way I could go through a formula file looking for an appreciable outside=atan result without manually changing the functions BACK to "asin" and "atan" (or whatever): Set and forget. Notice that in my above formula, if fn1=ident, fn2=ident, and P1=(2,4), then you get our first example (with six bells and two whistles to play with). fn1=zero does not make much difference.

Yummy, yummy - that's great! Looks like Pakman grabbed ALL the power pills! -- David gnome@hawaii.rr.com authenticity, honesty, community
Jay,
Last time I checked, the default functions were sin, and every time I changed fractal type, they were RESET to "sin". I would like to see the default functions changed to "ident", and the function reset operation deleted. That way I could go through a formula file looking for an appreciable outside=atan result without manually changing the functions BACK to "asin" and "atan" (or whatever): Set and forget. Notice that in my above formula, if fn1=ident, fn2=ident, and P1=(2,4), then you get our first example (with six bells and two whistles to play with). fn1=zero does not make much difference.
Insert the following line in your sstools.ini file: function=ident/ident/ident/ident or any other desirable combination. Jonathan

So nothing is here for you do to, thanks: [FRACTINT] function=ident/ident/ident/ident FLOAT=YES PERIODICITY=0 INSIDE=0 TYPE=FORMULA MAXITER=255 FASTRESTORE=YES MAXLINELENGTH=70 ________________________ The float choice is a choice for performance, at least in formulas. The ident choice lets me get a rough idea of what a formula does. The peridocity choice is about accuracy on deep zooms and inversions, even in the mandelbrot set, not a performance choice. I might change the inside colour choice, because it does not allow border tracing, and those are more fun to watch than the other pass options.

Usually it is fairly easy to play "editor" and correct the slight mistakes in the FOTD postings, but not sure about the above two. The first one says it is a new formula, but it has been used before in the past. And the second on has "XXXXXX minutes", but it actually renders in a few seconds.
