Beautiful. Too bad they didn't show the values of the a_n and b_n parameters.

- LegionMammal978 2y agoI thought to check the creation timestamps on the images, to see if I could bruteforce the RNG seed (which is just time(NULL)) and recreate the parameters. But the images currently shown on that page weren't created by the linked gen.c program; that only produces black-and-white images, as you can see in older versions of the page [0]. The current JPEGs were exported from Photoshop CS6 on January 23, 2019, according to their metadata. Presumably, the high-resolution curves came from some unpublished program, so one would presumably have to email Bourke to see if he still has it. (Though if you do still want to mess with gen.c, I'd note that the bitmaplib.c and paulslib.c dependencies can be found in S2PLOT [1].)
