; Date: Wed, 14 Apr 2010 00:19:26 -0600 ; From: Roger Alexander ; Subject: [Fractint] Tdis Coloring ; Id: ; --------- ; ; The scaly (layered?) appearance of todays fractals is the result of the outside=tdis combined with high ; bailout values. According to the Fractint manual tdis "colors the pixels according to the ; total distance traveled by the orbit." In these two formulas the bailout value can be directly inputed. ; Other formulas can be rewritten to allow the user to select the bailout values. The value of bailout that ; produces a desired effect varies with the formula and determined by experiment ( also known as ; taking a blind guess). This method does't work all time but often enough to give it a try. And as a ; no strings attached bonus is an Apr.11 gif resized then resampled. ; ; fract018.gif { ;_leafy_scales ; blank ; calctime 0:06:37.18 ; created Apr 13, 2010 ; Fractint Version 2004 Patchlevel 9 reset=2004 type=formula formulafile=_m.frm formulaname=magnet_spirals1 center-mag=1.32164/-0.780518/13.84275/1/144.999999999999972/7.6716411001\ 5983169e-014 params=-0.1222876674703207/0.8740195928830836/700/700 float=y maxiter=1500 inside=0 outside=tdis colors=0000z00z00y00y00y00y00x00x00x00x00w00w00w00w00v00v00v00v00u00u00u\ 00u00t00t00t00t00s00s00s00s00r00r00r00r00q00q00q00q00p00p00p00p00o00o00o\ 00o00n00n00n00n00m00m00m00m00l00l00l00l00k00k00k00k00j00j00j00j00i00i00i\ 00i00h00h00h00h00g00g00g00g00f00f00f00f00e00e00e00e00d00d00d00d00c00c00c\ 00c00b00b00b00b00a00a00a00a00`00`00`00`00_00_00_00_00Z00Z00Z00Z00Y00Y00Y\ 00Y00X00X00X00X00W00W00W00W00V00V00V00V00U00U00U00U00T00T00T00T00S00S00S\ 00S00R00R00R00R00Q00Q00Q00Q00P00P00P00P00O00O00O00O00N00N00N00N00M00M00M\ 00M00L00L00L00L00K00K00K00K00J00J00J00J00I00I00I00I00H00H00H00H00G00G00G\ 00G00F00F00F00F00E00E00E00E00D00D00D00D00C00C00C00C00B00B00B00B00A00A00A\ 00A009009009009008008008008007007007007006006006006005005005005004004004\ 0040030030030030020020020020010010010010000000000000000 } frm:magnet_spirals1 (XAXIS_NOIMAG) { ;needs floating point! ;p2 is the bailout (default=100) b=p2,b=b+(b==0)*100 z=c=pixel: z=( (z*z+(c)) / (2*z+(c-2)) )^2-p1 |z|
