Raw WebGL Programming: Build 3D Graphics with JavaScript and GLSL

Many web developers rely on heavy 3D frameworks without understanding how web graphics actually work under the hood. By learning to program directly with WebGL, you gain complete control over rendering performance and visual effects. This text-based course guides you through the process of rendering custom 3D graphics using vanilla JavaScript and GLSL shaders. You will transition from basic rendering concepts to writing your own custom shading pipelines from scratch. What you'll learn: - Understand foundational 3D graphics concepts, coordinate systems, and the WebGL rendering pipeline. - Configure the WebGL context and manage buffers, vertex arrays, and attributes using modern JavaScript. - Write custom vertex and fragment shaders from scratch using GLSL. - Apply mathematical transformations, including translation, rotation, and projection matrices, to manipulate 3D objects. - Implement basic lighting models and texture mapping to add depth and realism to your scenes. - Optimize rendering performance using modern WebGL best practices and efficient memory management. The course begins with essential theoretical foundations, explaining how the GPU processes data and how WebGL interfaces with your browser. From there, you will progress step-by-step through setting up a canvas, writing shaders, and rendering your first colored shapes before moving on to fully interactive 3D spaces. This course is designed for web developers with a basic grasp of JavaScript who want to dive into graphics programming without the abstraction of third-party libraries. No prior experience with computer graphics or matrix math is required. Start reading today to master the core mechanics of browser-based 3D graphics.
