WebGL Coordinate Systems and Shaders for Creative Coding

Every stunning 3D web experience relies on a solid grasp of spatial mathematics and coordinate systems. Without understanding how points move, rotate, and scale relative to an origin, rendering even a simple shape in WebGL can feel like guesswork. This text-only course demystifies the spatial foundations of creative coding. You will transition from guessing coordinates to precisely controlling 3D space, learning how to manipulate vertex positions and write custom shader code with confidence. What you'll learn: - Understand the core concepts of 2D and 3D coordinate spaces, including clip space, normalized device coordinates, and screen space. - Manipulate origin points and transformation matrices to position, scale, and rotate objects accurately. - Write basic vertex and fragment shaders using GLSL to control how shapes are drawn on the screen. - Apply mathematical patterns like sine, cosine, and vectors to generate dynamic, procedural visual effects. - Configure responsive canvas scaling to ensure your WebGL graphics look crisp on any screen size or device. The course begins with foundational definitions of 3D space and coordinate systems before guiding you through step-by-step written explanations and practical GLSL code snippets. You will explore how data flows through the graphics pipeline and how to structure your math for creative visual outputs. This course is designed for web developers, designers, and creative coding beginners who want to build a strong mathematical foundation for 3D web graphics. No prior WebGL or advanced math experience is required. Start reading today to unlock the power of spatial math in your web projects.
