When I ; started the FOTD on the Fractal Art list, I expected to post ; maybe 5 or 10 images, showing that complicated formulas are not ; necessary for interesting fractals. Since then I have posted ; over 4500 fractal images, and the supply of new images is in no ; danger of running dry. ; ; I think today's image is the only one I have created with the ; formula named 'bubbles'. The formula resembles one of my ; MandNewt series however, so I might have simply used the same ; formula under a different name. Curiously, the formula has no ; variable parameters. ; ; Most of the interest, which is in the bubbles, was created by ; rendering the image with the inside set to bof60. When the dust ; settled, I gave the result a rating of an 8, despite the fact ; that it is not entirely new. ; ; The name "Bubbles from the Past" needs no explanation. ; ; The calculation time of 1-2/3 minutes will seem like 30 seconds ; once the bubbles start popping into view. Or, to escape the ; popping, the finished image is instantly available on the FOTD ; web site at: ; ; ; ; Wednesday began with fog here at Fractal Central, but a strong ; sun cleared away the fog by 10am, leading to a sunny day with a ; temperature of 66F 19C, all of which kept the fractal cats happy. ; ; My day, as well as FL's day, was happy also. The work was light ; and the fractal, despite its venerable age, turned out pretty ; good. The next FOTD, perhaps another blast from the past, will ; be posted in 24 hours. Until then, take care, and dream fractal ; dreams. ; ; ; Jim Muth ; jamth@mindspring.com ; jimmuth@aol.com ; ; ; START PARAMETER FILE======================================= BubblesFromThePast { ; time=0:01:40.72-SF5 on P4-2000 reset=1950 type=formula formulafile=basicer.frm formulaname=bubbles float=y center-mag=+0.26701697\ /+0.92776452/101.211/1/50/0 float=y maxiter=250 passes=1 inside=bof60 logmap=yes periodicity=0 colors=000zzzzskzl`zdUs_HpUOnPMmJLkHKjFIhDHgBGe9Fd\ 7Db5Ca3BZ4CW5CU5DR6DO6EJ7KJ7RUUtUUtUUoUUoqaapaaoba\ obanbambalcakcajcajcaidahdaafZUhVNjSFlO8nL8nN8nQ8n\ S8nZ8nc8nh8nm8mr8pv8sz8vz8tz8qz8pw8lsGhoO`iXXcdcXl\ mRzzLrmNpcQnUSkKViLXgN_ePacQdaSf_UiYWkVYnTZpR`sPbu\ U_nZWgbT_gPTlMMjPMhSMfVMdYLb`L`cL_fLYhLWkLUnLSqKQt\ KOwKMzKKxLJuMHsMGqNEnOClPBjP9hQ7eR6cS4aS3ZT1XU4ZS6\ `R9bPBdOEfMGhKJkJLmHOoFQqETsCVuBYw9_y8`t9ap9bl9chA\ ddAe`AfXAgTAhPAiLBjHBkDBk9BnKJqVRtdYrdVpeSnePlfMkf\ JifFggCeg9ch6ah3`h0Zj3Yl6Xm9VoBUpETrHSsKQuMPvP7hh6\ ce5Zb4U_3PX2KU1FR3WP5mMt8jbFeLN_LUaL_bLfdLleLsgMzi\ KveIraFnXDjTAfP8bK5ZG9aICcLGfNMTRSEVY0ZZ1Z`2Ya4Yb5\ Yd6Xe7Xa8VY9TUAQRCONDMJEKFFHBGFDJDENCGQAIT8JW6L_5M\ b3Oe1Ri9TmGWqOYuV`ybXuaUp_QlZMhYIcWF_VBVT7RS7SO6TK\ 6UH5VD5W9Cz5gOjjadhKolUnocmsmleLpeWqdfrdqsiAhn9`_J\ nUSkN`iHiffPrgctirwb9o_8n } frm:bubbles {; Jim Muth z=c=pixel: a=sqr(z)+(c-1)*z-c b=3*sqr(z)+c-1 z=z-2*a/b, .000000000000000000000000000001 <= |a| } ; END PARAMETER FILE========================================= ; ; ; ; _______________________________________________ ; Fractint mailing list ; Fractint@mailman.xmission.com ; http://mailman.xmission.com/cgi-bin/mailman/listinfo/fractint ;
