WebGL & Shaders: Understanding Units and Scale

Ever wondered how complex 3D graphics maintain their proportions and spatial relationships on a screen? Mastering units and scale is fundamental to creating convincing and interactive visual experiences in creative coding. This course will guide you through the essential principles of WebGL and shaders, empowering you to precisely define and manipulate the size, position, and perspective of objects within your 3D scenes. You'll gain the foundational knowledge to build visually consistent and dynamic web graphics. What you'll learn: * Understand the core concepts of WebGL, including contexts, buffers, and drawing primitives. * Learn how vertex and fragment shaders work together to render pixels on the screen. * Apply different coordinate systems and fundamental transformations like translation, rotation, and scaling. * Implement uniform variables within shaders to dynamically control object properties and global scene parameters. * Practice structuring your WebGL and shader code for readability and maintainability. * Explore basic performance considerations for rendering efficient web-based 3D graphics. We begin with the absolute basics of WebGL setup and the shader pipeline, then progressively delve into coordinate systems, transformations, and how to control these aspects using shader logic. You'll move from conceptual understanding to practical application through step-by-step written exercises. This course is designed for absolute beginners in creative coding, WebGL, and shaders. No prior experience with 3D graphics programming is required. Start building your foundation in web-based 3D graphics today.
