What says fractal more than a spiral of self-similar spiral? Well if I get pedantic "fractal" says "fractal" more than anything else but I'm talking rhetorically here. This post has two graphics, a Fractint compatible gif and an anti-aliased jpg. I used my usual technique to anti-alias. The original 800x600 gif was regenerated to 3200x2400 resized to 800x600 in Gimp 2.6.8 sharpened a bit and saved as a 800x600 low compression jpg. To compare the two you'll have to go to http://maxitersfractalfollies.blogspot.com. fract279.gif { ; yas ; yet another spiral ; calctime 0:21:31.64 ; created Jun 27, 2010 ; Fractint Version 2004 Patchlevel 9 reset=2004 type=formula formulafile=_f.frm formulaname=F'ULI_8 function=sin/sqr center-mag=-1.09735/0.702671/14.63015 params=-0.09854426709799494/-0.3008209479049043/-0.8890957365642262/0.38\ 54182561723685 float=y maxiter=1500 inside=0 colors=000rC2rB1rA1rA1r91q81q71q71q61q51q51q41q31p20p20o20n20m20m20l20k2\ 0j20j20i20h20g20g20f20e20d20d20c20b20a20a20`20_20Z20Z20Y20X20W20W20V20U2\ 0T20T20S20R20Q20Q20P20O20N20N20M20L20K20K20J20I20H20H20G20F20E20E20E20D2\ 0D20C20C20C20B20B20A20A20A2092092092082082072072072062062052052052042042\ 042032032022022022012012001000000000000000000000000000000010010020040050\ 0700900B00D00G00I00L00O10Q10T10W10Z10a10e10h20k20o20r20v20y20z30z50z60z8\ 0z90zB0zC0zE0zF0zH0zI0zK0zL0zN0zO0zQ0zR0zT0zU0zW0zX0zZ0z_0za0zb0zd0ze0zg\ 0zh0zj0zk0zm0zn0zp0zq0zs0zt0zv0zw0zy0zz1zz3zz4zz6zz7zz7zy7zx7zx7zw7zv7zv\ 7zu7yt7ys7ys7yr7yq6yq6yp6yo6yo6xn6xm6xl6xl6xk6xj6xj6xi5xh5wh5wg5wf5we5we\ 5wd5wc5wc5vb5va5va5v`4v_4vZ4vZ4vY4vX4uX4uW4uV4uV4uU4uT4uS3uS3uR3tQ3tQ3tP\ 3tO3tO3tN3tM3tL3sL3sK3sJ2sJ2sI2sH2sH2sG2sF2rE2rE2rD2rC2 } frm:F'ULI_8 {; by Jon Horner - 100112,1700 - FRAC'Cetera z = pixel : z = fn1 (p1+z) + fn2(p2-z) |z| <= 16 ;SOURCE: uli.frm } Roger Alexander _________________________________________________________________ Learn more ways to connect with your buddies now http://go.microsoft.com/?linkid=9734388
