Here are some further variations on/investigations into Albrecht's recently posted (April 17, 2017) older fractal, mf102-x1. Albrecht's comment in his PAR file (below my signature) is: "PV from a preliminary MFR experiment" Be sure to view these images at full size in your browser! Parent Fractal ------------------- The parent fractal has two interesting discontinuities -- like fault lines -- one cutting across it, and the other cutting it off at the bottom. If you mentally expand the area between these fault lines outward from the center -- to "line up" the fractal's features above and below the top fault line -- it appears that the area between the fault lines has been "shrunk" by a small amount: http://www.emarketingiseasy.com/Albrecht/2017/A170417Z.gif The bottom left side of the parent fractal has a "tail" (anti-aliased X5): No "jaggies" (single pixel stair-steps) in the gentle curve at the left edge in the anti-aliased version! http://www.emarketingiseasy.com/Albrecht/2017/A170417Y.jpg The "fault tail at the edge of the world": http://www.emarketingiseasy.com/Albrecht/2017/A170417X.gif A muted study in brown: http://www.emarketingiseasy.com/Albrecht/2017/A170417W.gif The bottom center of the parent looks like it has a lot of potential: http://www.emarketingiseasy.com/Albrecht/2017/A170417V.gif There are definitely lots of places worth investigating here! : And that doesn't even reflect the possibilities of rotating the color map... http://www.emarketingiseasy.com/Albrecht/2017/A170417U.jpg Color map: http://www.emarketingiseasy.com/Albrecht/2017/A170417m.jpg Note: - The parameter sets below have X_Magnification_Factor set to 0.75 as a workaround for Richard's Fractint for Windows beta 5 (not for general distribution.) For use in DOS Fractint or XFractint, change the .75 to 1.0 -- either manually, after loading the parameter set into Fractint: <z> <F6> <edit XmagFactor> <Enter> <Enter> for each of my parm sets loaded using the <@> or <2> screen. Alternatively, edit each parm set's ".75" value in your copy of the parm file (pasted below.) E.g.: Change the ".75.": center-mag=317.131/2.27374e-013/0.0009910927/.75/90 to: "1.0" in the "center-mag" specification: center-mag=317.131/2.27374e-013/0.0009910927/1.0/90 Note: - My version: http://www.emarketingiseasy.com/Albrecht/2017/A170417A.gif of the fractal that Albrecht posted on 2017-04-17 is slightly different from his original: http://www.emarketingiseasy.com/Albrecht/2017/2017-04-17_MF215-X1.GIF In addition to a slightly different aspect ratio between our images, some areas of black in his fractal have non-black colors in them in my version. I don't know what caused the difference. - Hal Lane ######################## # mailto:hallane@earthlink.net ######################## ======= Albrecht's and my parms -- and his formula for 2017-04-17: ====== comment { This Image found today.
