Genuary 24: Homegrown RNG
January 24, 2022
This is a sketch for Genuary 2022, which provides a creative coding prompt for each day of January. This is day 24: "Create your own pseudo-random number generator and visually check the results."
I tried to make something approximating p5's noise() rather than random(). To do this, I wanted to stack a bunch of sine waves together in a way that would appear noise()-like. It uses octaves of noise, similar to noise, meaning that for each sine wave it stacks, it decreases the amplitude and increases the frequency. I use a bunch of primes to multiply the frequencies by in hopes that they won't constructively or destructively interfere too much or repeat in too small an interval.
