In addition to outside=atan and decomposition, tdis and outside=fmod can be used to provide smooth coloring. In today's post the fmod value was 0.1 instead of the default 0.01. With tdis high bailout values often provide the desired effect. Some formulas have the bailout as a user selectable parameter and I have rewritten some formulas to do this. Anyway on with the show. apr_21.gif { ; high fmod ; blank ; calctime 0:09:09.36 ; created Apr 21, 2010 ; Fractint Version 2004 Patchlevel 9 reset=2004 type=formula formulafile=_o.frm formulaname=Olio_Magnet function=cotan center-mag=-0.09106382978723393/-0.42499582637729420/5333.333 params=0/0 float=y maxiter=2600 inside=0 proximity=0.1 outside=fmod colors=000000111222333333444555666777777888999AAAAAABBBCCCDDDDDDEEEFFFGG\ GHHHHHHIIIJJJJJJKKKLLLMMMMMMNNNOOOPPPPPPQQQRRRRRRSSSTTTUUUUUUVVVWWWWWWXX\ XYYYYYYZZZ______``````aaabbbbbbcccddddddeeeeeeffffffggghhhhhhiiiiiijjjjj\ jkkkkkkllllllmmmmmmnnnnnnoooooopppppppppqqqqqqrrrrrrrrrssssssssstttttttt\ tuuuuuuuuuvvvvvvvvvwwwwwwwwwwwwxxxxxxxxxxxxxxxyyyyyyyyyyyyyyyyyyyyyzzzzz\ zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzyy\ yyyyyyyyyyyyyyyyyyyxxxxxxxxxxxxxxxwwwwwwwwwwwwvvvvvvvvvuuuuuuuuutttttttt\ tsssssssssrrrrrrrrrqqqqqqpppppppppoooooonnnnnnmmmmmmllllllkkkkkkjjjjjjii\ iiiihhhhhhgggffffffeeeeeeddddddcccbbbbbbaaa``````______ZZZYYYYYYXXXWWWWW\ WVVVUUUUUUTTTSSSRRRRRRQQQPPPPPPOOONNNMMMMMMLLLKKKJJJJJJIIIHHHHHHGGGFFFEE\ EDDDDDDCCCBBBAAAAAA999888777777666555444333333222111000 } Olio_Magnet (XAXIS) { z = pixel : z = z + p1 + 0.5 z = z * fn1(pixel) z = sqr(1/z) |z| < 4 ;SOURCE: olio.frm Go to http://maxitersfractalfollies.blogspot.com for the finished fractal _________________________________________________________________ Live connected.
