But it should have been no problem since I ; have posted the MandAutoCritInZ formula hundreds of times. ; ; A question has arisen about the calculation time of the FOTD ; images. The time listed in the parameter file is the time I ; estimate the images would have taken to calculate on the Dell ; P4-2000mhz unit, the up-and-down machine that is currently in ; down mode. All FOTD images are presently being calculated on ; the ancient nameless 11-year-old Pentium-200mhz machine, which ; still runs like new. (Not much to say for Dell hardware.) I ; simply edit the calculation time, cutting it by 75 percent to ; convert the time. Yes, the 2000mhz unit runs only 4 times as ; fast as the 200mhz machine. (That is except for the type=mandel ; and type=julia, where it runs 20 times as fast.) ; ; Today's image lies on the northwest shore line of the egg-shaped ; Mandeloid that results when Z^2 is subtracted from 0.5 part of ; Z^3 before C is added. ; ; To add a bit of interest I rendered the image with the outside ; set to 'tdis'. Then I named it "Pales by Comparison". The name ; came about when I had to tone down the too-intense warm reds. ; The listed calculation time of 3-1/4 minutes is actually 1/4 of ; the actual 13-minute calculation time on the Pentium 200mhz ; machine. The rating of a 6 is average. ; ; So why not forget all this calculation confusion by viewing the ; completely-calculated image on the FOTD web site at: ; ; ; ; Stifling 93F 34C heat and 75-percent humidity prevailed here at ; Fractal Central on Tuesday until it was broken up at 5pm by a ; cooling thunder-shower that dropped the temperature to a far ; more reasonable 73F 23C. The evening was then quite pleasant. ; ; The fractal cats would have been happier if the cool-down had ; come earlier, but they hung in there bravely and were finally ; rewarded. My day was busy. The next FOTD will be posted in 24 ; hours. Until then, take care, and never give up the search. ; ; ; Jim Muth ; jamth@mindspring.com ; jimmuth@aol.com ; ; ; START PARAMETER FILE======================================= PalesBy_Comparison { ; time=0:03:14.85-SF5 on P4-2000 reset=2004 type=formula formulafile=basic.frm formulaname=MandAutoCritInZ function=ident passes=1 center-mag=+0.582575936368227/+0.8363401268104876/\ 9.677674e+009/1/-20/0 params=0.5/3/-1/2/0/0/0/0 float=y maxiter=4200 inside=0 outside=tdis logmap=35 periodicity=10 colors=000u_Ov`LwaIxaFyaCxa9v_8tY8rW7qT7oR6mP6lN5j\ K5hI4gG4gD3fB3e92e72fD5fJ8fPAkVDq`GqfIqlLqrNosQnsS\ msVktXjtZitagucfufeuhcvjbvmavo`vqVwlQwgLwcFxZAxU5x\ Q8wSAvUCuWEtYGs_IraKrcNqePpgRoiTnkVmmXloZlq`kjbjdc\ iYehSggLhgFToyTpyTpyUpyUpyUpyUqyUqyUqyUqyUqy1`S2aT\ 2aT2aU3aU3aU3bV4bV4bV4bW4bW5bW5cX5cX6cX6cY6cY6cY7d\ Z7dZ7dZ8d_ThZ_oSfuLblNZdPWXQSPSOHUL9VGFkbXOym1nh2d\ d3V_4LW5ITPFQgCNz8cy5txGhoNekUch``efZbgNXhCSh1NlB_\ oLlZAjJ0iF7aBEUAIQ9LN9PK8SH8VE7SC7QB6N96L86J7GPBPV\ FY_IfeMojPbYUQLYVMWZNUbNSfOQkPOoPMsQKwQJpMKjJLcFLY\ CMR8NL5NP6UT7`U7YV7VV7RW7OW7LSESOLZLRdHYkEcqDXpDQp\ EQpEQpEQpERpERpERpERpERpESpFSpFSpFSpFSpFSqFTqFTqFT\ qFTqGTqGUqGUqGUqGUqGUqGVqGVqGVqHVqHVrUpxHVrHWrHWrH\ WrHWrHWrHXrIXrIXrIXrIXrIYrIYrIYrIYrIYsJYsJZsJZsJZs\ JZsJZsJ_sJ_sJ_sK_sK_sK`sK`sK`slThkTlkTokTskTvlUrmV\ onVloWipXfqXcrY`rYYsZUt_R } frm:MandAutoCritInZ {; 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)+(p4)), 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========================================= ; ; ; ; _______________________________________________ ; Fractint mailing list ; Fractint@mailman.xmission.com ; http://mailman.xmission.com/cgi-bin/mailman/listinfo/fractint
