; May 30, 1997: At the Limit ; ; limit ; ; Fractal visionaries: ; ; Today's fractal has a squeezed, uneasy feeling about it. It is not ; beautiful. It is a picture of a rather ordinary midget buried deep in ; the northeast corner of the Mandelbrot set. What makes this midget ; unusual is that I caught it as it was being squeezed by an ever ; decreasing bailout radius, and ready to be swallowed up. ; ; When a midget is very close to the escape radius, (something that can ; happen only when the escape radius is set to less than two), the ; character of its surroundings totally changes. Instead of lacy chaos, ; such squeezed midgets are surrounded by blobs of color pushing in toward ; them. The iteration count of these blobs is not in order, but jumps ; around in a random manner, which makes coloring these fractals ; difficult. ; ; This same effect is what makes the tiny midgets far out on the negative ; x-axis so attractive when the bailout is set to 4 and they are therefore ; near the escape radius, and so plain when the bailout is set to 100 or ; so. ; ; The exact bailout setting where a particular midget distorts like this ; is rather critical. It must be found by trial and error, bracketing and ; closing in on the exact point where the screen goes blank. It cannot be ; done with the hard-coded Mandelbrot formula because Fractint permits ; only integer values to be entered for the bailout. ; ; The picture takes 25 minutes to draw on a 486-100mhz machine at 640x480 ; resolution, and is posted to a.b.p.f. and a.f.p. ; ; Jim Muth ; jamth@mindspring.com ; ; START PARAMETER-FORMULA FILE FOR 19.6============================== At_the_Limit { ; time=0:02:29.45-SF5 on P4-2000 reset=1960 type=formula formulafile=basicer.frm formulaname=Mandelbrot center-mag=+0.3511154645682\ 388/+0.4139810894457739/1.624429e+010/1/-95/0 params=0/0/0.950077/0 float=y maxiter=14000 inside=0 logmap=1526 periodicity=10 colors=000KBZ`byKQjsCBMlUHcVCVW7MX9Fk7Ef5DaZyR0vi1\ je2_b3O_BqF9fK7XO5NTIdKEYOARR6KUN7EI9JDAO8CTduXMZX\ vAjhBfVCcHD_sWaPp2HbDAQNknCXaJIPQlDecB6LCKobYXY`4m\ b3V_vzRVaURyFLlKF`O9PTJOrCGv58zei5Bi_HWWNJTT6QPDJM\ JCTGJZEQQLJHSDZ3LNOJCgHFcRI``LYjOVsvSa1lmDqoOupZyq\ HXS042ed_WYZUaEMRYCKXWJcMH`CFZGBNBCR7DU3v2J4ctvEfj\ JU_OGOTp9wcApSBiFCbvvPV_ToC0ISGAKPUnJGWQ_AxJCjJINF\ GQBFS7EVhYdoeabY_RRZFKYQKhKIeEGb8E_isoOYeCGTt5KC4g\ s3fe6cT8aGBZTJgMHdGGa9EZ1h72`E2TK3LRvVsGqSBcU7QWwP\ ChMIVJNHGSYpjIXccLzLHkrb``UZKLY`h`KTZsitTThNXSCSUf\ D2TDDGDNI66E8DAAK6CRyRC0VG1PM2JSr3FT8OkQZ_MYPJYEGX\ 3Ic3F_FMfBJb7G_utFbeLLRRuH3gGBUFIGEQj_NPOSvV1VMH`O\ GPKMEGSsmoa`hKPbfOHXLLNIPDFT0Xx2Nj_Pg8yR5`UonCbdIR\ WNFMSDgPzSTLYqz7bI9`zBZzFtzBPzzTzzxZzEzzzQzrIzkAzc\ zz0zzHzzuRzzzzrFzkzzcazgzzazzCzzJzzQzzFzzKzzOzzTzz\ ZzzYzzXzzmzzgzzazzezzbzz` } frm:Mandelbrot {; Jim Muth z=p1, c=pixel: z=sqr(z)+c, |z| <=p2 } ; END PARAMETER-FORMULA FILE FOR 19.6================================ ;
