A Procedural Polka Dot Shader with Analytic Normals

Today we’ll build a procedural shader that produces a polka dot pattern. While this is quite informative, as we learn how to tile the uv space, the interesting part is creating the normal map. We want to use the implicit sphere equation to derive z […]

Essential TD Skills: Designing & Implementing Algorithms

A popular misconception we often encounter when answering questions, is the notion that in order to simulate an effect A that looks somewhat similar to another algorithm we built to simulate effect B, all you need to do is tweak a few parameters. While true […]
