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.
