; June 30, 1997: Bursting Bubble ; ; bubble ; ; Fractal visionaries: ; ; My Fractal of the Day series seems to have taken on a life of its own. ; You can imagine my surprise when I returned from my short break and ; checked my mailbox only to find the F.O.T.D. 29-06 waiting. Lee did a ; fine job in my absence. The image itself is most interesting. It took ; about an hour to draw a 1024x768 version at 100mhz, but it was worth the ; effort. ; ; I can see why Lee named his picture "Land of the Lost". It reminds me ; of a view from high overhead of a devastated area, with smoke, fire and ; ruination still everywhere. I've never been too interested in the PHC ; trick of overlaying different images to get the effect of more colors ; than are actually available. Of course this may be because I've seen ; such images only at a resolution of 1024x768 -- the limit of my ; monitor. And at that resolution the checkerboarding is still visible. ; Later this year when I purchase my new machine, I'll pick one with ; 1600x1200 capability. Maybe then I'll change my mind. ; ; But even now, I see potential in this method. I especially admire the ; effect of overlying haze, most evident in the lower right part of the ; picture. This method could be used to create atmospheric effects in ; fractal landscapes. Perhaps some fractal artists are already doing ; this. ; ; One thing is immediately apparent: when true true color arrives, we're ; going to need something other than those awkward and unattractive ; equal-iteration bands to define the colors. Some of the methods I've ; seen discussed in this group have great potential. I'll be glad when I ; have the equipment to give them a fair test. ; ; Today's fractal is named "balloon". I named it because it appears to be ; a square pattern printed on an inflating balloon. It's a version of the ; Z^(-3) mandeloid turned inside out by the C^8 in the reiterative ; section. I colored it rather hastily, but it's still an acceptable ; picture. ; ; The finished image has been posted to a.b.p.f. and a.f.p. Tomorrow, ; I'll explore one of the more remote planes of today's figure. ; ; Jim Muth ; jamth@mindspring.com ; ; START FILE FOR 19.6======================================== Bursting_Bubble { ; time=0:00:07.03-SF5 on P4-2000 reset=1960 type=formula formulafile=basicer.frm formulaname=JimsCompMand passes=1 center-mag=0/0/\ 0.6397608 params=-3/0/8/0/0/0 float=y maxiter=300 inside=bof60 logmap=yes symmetry=xyaxis periodicity=10 colors=00000R70U06RT9RbCRdFReIRgLRhORjRRlURmXQo_Qp\ bQreQshQukQvnQxqQxpRwoSwnSwnTvmUvlVukVujWuiXtiYthY\ tgZsf_se`rd`rdarcbqbcqacq`dp_epZfoZfoYgoXhnWinVinU\ jmUkmTllSllRmlRmkSljSliTkhTkgUkfUkeVjdVjcWjbWjaWi`\ Xi`Xi_YiZYhYZhXZhW_gV_gU_gT`gS`fRafQafPbfObeNceMce\ LceKddJddIedHecGfcGfcFgcEgbDgbChbBhbAia9ia8ja7ja6k\ `5k`5k`6ja6ia7hb7gb8gb8fc8ec9dc9cc9bdAbdAadB`eB_eE\ bgHeiKhkNkmQnoSpqTopTopUnoUnoVmnVmnVlmWlmWklWklXjk\ XjkYijYijYiiZhiZhh_gh_gg_fg`ff`ef`eeadeaddbcdbccbc\ c`beZafX`hW_iUZjSYlQXmOWnNWpLVqJUrHTtFSuERvCQxAPyB\ QxDRwESvGTuHTtJUsKVrMWqNXpOYoQZnR_mT`lU`kWajXbiZch\ _dh`egbffcgeehdfhchibijakk`ll_mmZonYpoXrpWspVuqUvr\ TxsSytRxsSxqTwpUvoVumWulXtkYsi_rh`rfaqebpdcobdoaen\ `fmZglYhlXikVjjUkiTliRmhQngOpfNqfMreKsdJtcIucGvbFw\ XLuRStLYrFcp9jo3pmvznuyluyktxiswhrvfrvdqucptahXvhY\ whYxhZygWufSqePmdMicIebFa } frm:JimsCompMand {; Jim Muth z=c=pixel: z=z^p1*(c^p2)+c, |z| <= p3+100 } ; END FILE FOR 19.6========================================== ;
