HI, ; one of the "secrets" responsible for the indifinite versatility of MFR12 is my baby, the Warp Effect. The purpose is to mofify a part of the image from a light modification up to "Warp 9", thanks Gene Roddenberry. ; It consists of 3 elements: The warp factor taken from the input screen, the iteration counter and a function, 1 of 4 in the bottom line.That means the warp effect changes with every iteration. It is applied to "z" or P1, mandel or julia type. ; It works with every frm used and can be used separetely for every channel, main, outside, inside1 to 3. ; Pnncipally it can be used with most formulas and therefore should be interesting for all formula writers - questions are welcome. ; The link contains 7 modifications of the Secant formula plus the basic view. And - sorry, already a new version of the plugin, this time an important improvement ,not a bugfix and it?s necessary to calculate above images. ; It?s purpose is to generate better basic images, independant from functions and closer to the original formula. It is activated by adding "5" to digit 7, Real P2 after the dot. ; Within some days I will add new basic images to the Startup Basic Images folder.
