Possible to make a Collatz fractal in Fractint? Just wondering. https://en.m.wikipedia.org/wiki/Collatz_conjecture -David W. Jones It might be possible. It would also depend on which view of the Collatz Conjecture's properties you want to display.
It's easy (and fun) to write the code to calculate and display the sequence of "hailstone numbers" referred to in the Collatz conjecture in a normal development environment. However, if you want to use Fractint to show the sequence of hailstone numbers galloping along or the properties of the members of the sequence, like "stopping time" or "highest number reached," it could be a fussy proposition -- given Fractint's pixel writing sequencing assumptions... It may be possible to force existing Fractint built-in formula types to write a pixel to a given (X, Y) location... E.g.: I saw in the Fractint Docs that L-Systems have "Move Forward" and "Draw Forward" commands, although I don't immediately see a practical way to use this particular draw command because of the L-system framework it's included in. Anyone know if there's a way for a Fractint *formula* to write a pixel to a given (X, Y) location -- the way that Fractint's built-in orbit fractal formulas (like Lorenz) do? The 20.0 Fractint docs say that "scrnpix" is a "Predefined Variable (x, y)": scrnpix (col, row) pixel screen coordinates. (col, row) ranges from (0,0) to (xdots-1, ydots-1) but I don't know if it's read only or what Fractint's behavior is if you write to it.
