Improving the 2D Noise page #
One of my goals for 2019 is to improve my existing pages. Yesterday I decided to work on my old 2D noise page. We normally use Perlin/Simplex noise to make terrain heightmaps, but on that page I used Fourier transforms instead. Perlin/Simplex noise are a fast approximation of the things you can get from Fourier transforms.
The 3D renderer on that page always bothered me. It was one of my early experiments with WebGL. I had never been able to figure out exactly what I didn't like or how to fix it.
I decided to improve the renderer.
