CGI Texture Mapping: Normal Maps and Bump Maps Explained

Creating realistic surfaces in 3D computer graphics requires a solid understanding of how light interacts with textures. If you have ever struggled to grasp how normal maps differ from bump maps, you are not alone. This text-based course guides you through the fundamental principles of CGI surface detailing. You will understand how different mapping techniques simulate depth and texture, allowing you to optimize your 3D assets for modern rendering pipelines and game engines without adding unnecessary geometry. What you'll learn: Understand the core differences between bump maps, normal maps, and displacement maps; Explain how RGB color channels represent 3D surface vectors along the X, Y, and Z axes; Analyze tangent space versus object space normal maps and when to use each; Apply Physically Based Rendering (PBR) workflows to enhance surface realism; Configure texture settings for seamless compatibility with modern game engines; Practice troubleshooting common normal map artifacts and shading errors. The course begins with foundational terminology, defining the physics of light and surface interaction. You will then progress through the mechanics of vector-based mapping and explore how to apply these concepts to modern real-time and offline rendering workflows. Designed specifically for beginner 3D artists, game developers, and CGI enthusiasts, this course requires no prior experience with advanced texturing.
