the binding of fraactal

The function takes a bunch of pairs of starting pairs, then keeps squaring and adding until either it flies off to ∞, or it hits the max number of iterations (the sharpness value).

We can't just check if the number is going to ∞, but once it goes past a certain size, we can make a reasonable guess that it'll never settle to a value (I have the tolerance set to 16).

Once we have the full grid of values, we can generate a grid of white squares, then change their brightness based on how many iterations it took to fly off (or default to black if it reaches the maximum)

As for why? Well, I realized a while ago that making generic Isaac mods isn't as fun as making something completely unique and ridiculous, and I've kinda been acting on that philosophy ever since I made the Bejeweled mod last year. It's been fun so far, and I have a bunch of insane ideas that I want to try.

(I'm working on an Isaac RPG proof-of-concept as we speak )

@aviess
It's not as complicated as it looks (at least I don't think it is lol):

The way the Mandelbrot set works is by taking a range of values, feeding them into a function, then repeating that process until they either settle to a value or fly off to Infinity.

The function is y = x^2 + c, where x and c are complex numbers written as (a + bi). That sounds scary, but a complex number in this context is just a pair of numbers with slightly different behavior when you multiply them together, since i^2 is -1. There's some correlation between complex numbers and rotation around a circle that makes the visualization do a lot of the crazy stuff that it does, but that's not really important for this explanation.

You can technically use any pair of numbers for c, and any other value's graph is called a Julia set, but I used (-1, 0) for the classic image.

this is really cool actually. how did you do it, and why? LMAO

this is just like the FIST campaign kit MANDELBROT SET!

RG JUBILEE was right the mandelbrot is from god

a mod that nobody ever asked for, but we got anyways. thank you!

Am i stupid? i dont know what this is!

Thank god someone finally made this

this is insanely fucking cool

yeah that's cool

top tier mod

bro what

HOW just how

i did this in javascript at school once

This is bad-ass.

Benoit would be proud.

Science isn't about "why?". It's about "why not?".
