1. Overview
This document implements monolith_fbm, a seed for
a stateless fractional brownian motion algorithm.
monolith_fbm takes in an xy coordinate pair, expected to
be normalized in range 0-1, as well as the number of
octaves. It will return a normalized amplitude. fbm calls
can be mixed and matched together and warped with time
to create 2-dimensional swirls of color.
This FBM algorithm is based on some of code snippets found in the book of shaders, except instead of shader code on the GPU, it's C code on the CPU.
