GLSL Antialiasing and Creative Coding for WebGL Shaders

Jagged, pixelated edges can instantly ruin the aesthetic of your digital art and WebGL projects. Understanding how to mathematically smooth these boundaries within fragment shaders is a fundamental skill for any creative coder. This text-based course guides you through the core principles of shader-based antialiasing. You will transition from rendering raw, pixelated shapes to crafting silky-smooth visual elements entirely through code, gaining a deep understanding of how GPU rendering handles edges. You will learn to: Understand the foundational math behind pixels, coordinates, and aliasing in WebGL; Implement custom antialiasing algorithms using the GLSL smoothstep function; Apply screen-space derivatives to achieve resolution-independent edge smoothing; Structure fragment shaders cleanly using modern modular workflows; Analyze the performance impact of different antialiasing techniques on mobile and desktop GPUs; Practice writing clean, mathematical shader code to render perfect procedural shapes. You will start with essential terminology, learning how the GPU processes fragments, before moving on to practical formulas and code implementations. The lessons progress systematically from basic edge smoothing to advanced derivative-based techniques. This course is designed for web developers, creative coders, and digital artists who want to dive into the math of beautiful shader graphics, with no prior shader experience required.
