Creative Coding with Three.js: Building Custom WebGL Geometries

To create truly unique interactive 3D web experiences, you need to go beyond standard boxes and spheres. Understanding how to build custom geometry from scratch is the key to unlocking unlimited creative freedom in WebGL. This text-based course guides you through the foundational math and code needed to construct your own 3D shapes. You will transition from using pre-made templates to designing bespoke 3D structures and writing custom shaders that define how they look and move. What you'll learn: Understand the core concepts of WebGL, vertices, faces, and coordinate systems; Build custom 3D shapes from scratch using modern Three.js BufferGeometry; Manage vertex attributes such as positions, normals, and colors using typed arrays; Write custom vertex and fragment shaders using GLSL to control shape and appearance; Apply performance best practices to ensure smooth rendering in the browser; Practice your skills through structured, step-by-step written coding exercises. You will start with essential terminology and the mathematical foundations of 3D space before moving on to hands-on implementation. The course walks you through defining vertices, mapping colors, and integrating custom shaders for dynamic visual effects. This course is designed for web developers and creative coders who are new to custom WebGL geometry. No prior advanced math or shader experience is required. Start reading today to build your own custom 3D creations on the web.
