Forget about the ersatz ; 'new' formula posted on August 4th, which has already been ; discarded. ; ; ------------------------------------------------------------- ; BranchCutGen { ; Jim Muth ; Z=C=Pixel: ; Z=log(Z), ; Z=exp(real(p1)*(Z+flip(imag(p1))))+C, ; |Z|<36 } ; ------------------------------------------------------------- ; ; Given impetus by Hal Lane, I decided to see how much I could ; simplify the BC formulas and still get the same fractals. ; Today's formula is about as far as I could take the process. ; When I analyzed the old formulas, I was surprised at how many ; terms simply canceled out or had no effect. Today's new formula ; is the result. The by-product is a 33-percent increase in speed. ; ; I named today's image "The FMOD Cycle" mostly because the image ; was rendered with the inside set to 'FMOD'. The cycle part of ; the name refers to the complex logarithmic hyperspiral of the ; Z^sqrt(2)+C fractal, which, starting at zero, repeats every ; 4.442... levels. Today's image is located 2.221... levels up ; the hyperspiral, which is exactly halfway back to the starting ; point and produces a parent fractal with X-axis symmetry. ; ; The art worth of the image impresses me as a 7; the math rates ; an 8, which is perhaps overblown. After all, the basic math is ; old stuff. Only the streamlined formula is new. ; ; Today's image is the actual parent fractal, made somewhat ; unrecognizable by the 'FMOD' inside fill. This is why it ; calculates in a matter of 22 seconds. If this is still too ; slow, the web sites can make things a bit speedier. ; ; Check the finished images at: ; ; ; ; ; ; ; ; ; ; A mix of puffy clouds and blue sky, a temperature of 79F 26C, a ; passing afternoon shower, refreshing low humidity, and a gentle ; north wind made today a day worth waiting for here at Fractal ; Central. The fractal cats missed much of the day when they ; slept all afternoon. The fractal humans had an uneventful ; though busy day. ; ; The next FOTD will be posted in the appropriate time. Until ; whenever this might be, take care, and the governments tell the ; people what they can and cannot do, the big corporations tell ; the governments what to order the people to do, but who tells ; the big corporations what to tell the governments to order? ; ; ; Jim Muth ; jimmuth@earthlink.net ; ; ; START PARAMETER FILE======================================= The_FMOD_Cycle { ; time=0:00:22.00 SF5 at 2000MHZ reset=2004 type=formula formulafile=basicer.frm formulaname=BranchCutGen center-mag=-0.0840312/0/\ 0.778816/1/0 params=1.414213562373/2.22144146907933 inside=fmod float=y maxiter=1500 symmetry=xaxis proximity=0.049 periodicity=6 colors=000MCcLCbKBaKB`KB`JB_JBZJAZIAYIAYIAXHAWH9WH\ 9VG9UG9UG9TF8TF8SF8RE8RE8QE8QD7PD7OD7OC7NC7MC6MB6L\ B6LB6KA6JA5JA5I95H95H95G84G84F84E74E74D74D63C63B63\ B53A5395294284284273263163152142142131031021010010\ 00cGFbFEaFE`ED_EDZEDYDCXDCWDCVCBUCBTBBSBARBAQAAQA9\ PA9O99N98M88L88K87J77I76H76G66F65E55D55D54C44B44A4\ 3933833722622522411311211100000ol5mj4li4jg4if4ge4f\ c4db4f`ngangbngcngdngengfnggnghnhinhjnhknhlnhmnhnn\ honhpniqnirnisnitniunivniwnixngvlftkericqhcpgbofam\ e_kcZjbYh`Wf_VdYUcXSaWR_UQYTOXRNVQMTOLRNJQLIOKHMIF\ KHEJGDHEBFDADB9CA7A8687565354232111shJqfIoeHndHlcG\ kaGi`Fh_FfZEeXEcWDaVD`UCZSCYRBWQBVPATNASM9QL8OK8NI\ 7LH7KG6IF6HD5FC5EB4CA4A83973762652431321110kyYiwXh\ vWgtVfsUerUdpTcoSbmRalR`kQ_iPZhOYgOXeNWdMUbLTaLS`K\ RZJQYIPXIOVHNUGMSFLRFKQEJODINCHMCGKBEJADH9CG9BF8AD\ 79C68B6795684563453342221 } frm:BranchCutGen { ; Jim Muth Z=C=Pixel: Z=log(Z), Z=exp(real(p1)*(Z+flip(imag(p1))))+C, |Z|<36 } ; END PARAMETER FILE========================================= ; ; ; ; _______________________________________________ ; Fractint mailing list ; Fractint@mailman.xmission.com ; https://mailman.xmission.com/cgi-bin/mailman/listinfo/fractint ;
