Signal Processing in Computer Graphics #1: Overview

Rendering an image is essentially a sampling process: a continuous image, with its geometry, colors, and lighting, needs to be sampled and converted into pixels on the screen. These brief notes provide a quick introduction to signal processing, filtering, and aliasing. In the final chapter, there are some ShaderToy examples that demonstrate some anti-aliasing algorithms.
