I can give no ; logical reason for choosing such a name -- the triangular holes ; in the image certainly appear harmless enough -- I simply felt ; like naming the image that way. And there certainly are enough ; junky old sci-fi horror movies with similar names. The most ; likely reason for the name could be the doom the triangles would ; bring if the fractalist who found them were to become obsessed ; with them, and stare at them until he starved. ; ; The rating of an above-average 7 was earned by the coloring, ; most notably the effect of the translucent foreground features ; being illuminated from behind. This effect is achieved by ; filling the holes with the maximum value of blue, and varying ; the red and green only slightly from the maximum. This tricks ; the mind into thinking that it is actually viewing the sky ; through holes in trees. ; ; The parent fractal of today's image appears as a scattering of ; small Mandeloids and an assortment of other, more oddly shaped ; holes. The most prominent Mandeloid has both a negative stem ; that points northwest and a positive stem that points southeast. ; The positive stem springs from East Valley and terminates in an ; irregularly shaped hole that passes through the neck of many ; smaller hourglass-shaped holes on the way. Today's scene is ; found close to the point where this spurious stem terminates. ; ; When colored in my usual inside=0 outside=iter manner, today's ; scene is dull and flat. But rendering the image with the ; inside=bof61 and the outside=tdis, results in the interesting ; terraced effect seen in today's image. I am not an absolute ; purist when it comes to fractals, but when I work with them, I ; try to keep the simplicity that existed when I first discovered ; them some 16 odd years ago, and had only the Mandelbrot set to ; explore. Maybe one of these months I'll devote a month to ; scenes in the M-set, just to show that it is nowhere near being ; exhausted. ; ; The render time of 2-1/2 minutes is reasonably short. And this ; time can even be cut a bit more by downloading the completed GIF ; image from one of the FOTD web sites at: ; ; ; ; and: ; ; ; ; Monday featured nothing but blue skies and sun here at Fractal ; Central. The temperature of 50F 10C was a bit on the chilly ; side, but the fractal cats ignored the chill as they explored ; the holly thicket at the bottom of the yard. The day ended with ; happy cats sleeping soundly (Thomas snores). Today is starting ; sunny and promising to be warmer. The warmth is due to be temp- ; ered this afternoon however by clouds and perhaps a few showers. ; We'll just have to wait and see how it goes with the dynamic ; fractal feline duo. ; ; As for me, I have a bit of work to accomplish before the ; fractals can be found. Until next FOTD, take care, and don't ; take life too seriously. It won't last forever. ; ; ; Jim Muth ; jamth@mindspring.com ; jimmuth@aol.com ; ; ; START PARAMETER FILE================================ Triangles_of_Doom { ; time=0:02:23.90--SF5 on a P200 reset=2002 type=formula formulafile=allinone.frm formulaname=MandelbrotMix4 function=recip passes=1 center-mag=+0.72147391460799470/+2.077828375552933\ 00/16687.84/1/25/6.03698577933409197e-009 params=-1.5/-1/0.15/5/0/0 float=y maxiter=1250 inside=bof61 outside=tdis periodicity=10 colors=000Kt_MubOudQufSvhUvjWvuYwn_wpawrcwtcvrcuqc\ upctocsncsubnlajzafj`bi_Zh_Vgb_hedhhihknvrsznrzjre\ frcbq`ZqYVqWRpTNpQJpOFoLBoI4qDAtGAmJDiMGePIaRK`QL`\ PM`ON`NPXMQTLRSKSMJULIVKHWJGXIFZHE_FD`ECaDBcCAdB9e\ A8f97gC6gF6hH6hK6iM5iP5jR5lU5mX5oZ4pa4rc4rf4rh4ni6\ li8iiAgiCdiEbjG_jIYjKVjMTjOQjQOkSMkUKkWIkYGk_ElaCl\ cAle8lg6li4ljHkoUksTgrTdrS`rSYqRUqRRqRNpQKpQGpPDoP\ 9oP6oQ8nR9mSAmTBlTDkUEkVFjWGiXIiXJhYKgZLg_Nf`Oe`Pe\ aQdbSccTcdUbdVaeXafY`gZ_g__fRSeILd9Ed17f79gCAhHBiN\ CjSEkXFlbGmhHnmHnlIljJjhKhfKfdLcaMa_M_YNYWOWUOTRPR\ PQPNQNLRLJSHERJHSLJSNLTPOTRQUTSUVUVXXVZZW``WbbWcaX\ c`Xd_XdZXeYXeYXfXXfWYgVYgUYhUYhTYiSYiRYjQZjPZkPZkO\ ZlNZlMZmLZmLZeQVZVRR_NKdJCiF5mB6nF7nJ8nN9nRAnVAnYB\ naCneDniEnmEnnEnoGlnIkmJjkLijMghOfgPeeRddSbbUaaV`_\ X_ZYYX_XW`WUbVTcTReSQfROhQNmPGiPMePRbPWZP`VPeSPjOP\ oKPtHPyJRuKSqLTmMViVjUPoX } frm:MandelbrotMix4 {; Jim Muth a=real(p1), b=imag(p1), d=real(p2), f=imag(p2), g=1/f, h=1/d, j=1/(f-b), z=(-a*b*g*h)^j, k=real(p3)+1, l=imag(p3)+100, c=fn1(pixel): z=k*((a*(z^b))+(d*(z^f)))+c, |z| < l } ; END PARAMETER FILE================================== ;
