WebGL Shader Art: Crafting Animated Circular Mask Patterns

Bring your web graphics to life by mastering the mathematical beauty of shader art. This text-based course guides you through the core concepts of WebGL and GLSL to create hypnotic, recursive visual patterns. You will transition from writing basic rendering code to crafting sophisticated, animated circular mask patterns applied directly to 3D geometry. By understanding how pixels calculate their color dynamically, you will unlock a highly efficient way to build modern, high-performance web visuals. What you'll learn: Understand the foundational math behind GLSL fragment shaders and coordinate systems; Create clean circular masks using distance fields and step functions; Apply recursive logic to generate intricate, repeating geometric patterns; Animate shader patterns smoothly using time uniforms and mathematical functions; Optimize shader performance for modern web browsers and mobile devices; Map custom fragment shaders onto 3D box geometry using modern WebGL setups. The course starts with essential shader terminology and setup before walking you step-by-step through writing, testing, and refining your first recursive visual patterns. Designed for frontend developers and creative coding beginners, this course requires only basic JavaScript knowledge and no prior WebGL experience.
