Baking Textures
Baking textures is a 3D computer graphics technique where complex lighting, shading, or geometry information is precomputed and stored as texture maps (e.g., normal maps, ambient occlusion maps, or lightmaps) to optimize real-time rendering performance. It involves transferring data from high-polygon models or detailed simulations onto low-polygon models, reducing computational load during runtime. This process is essential in game development, architectural visualization, and animation to achieve high visual fidelity without sacrificing frame rates.
Developers should learn baking textures when working on real-time applications like video games or VR/AR experiences, where performance is critical and dynamic lighting calculations are too expensive. It's used to create realistic surfaces with details like shadows, wrinkles, or material properties that would otherwise require complex shaders or high polygon counts. For example, baking ambient occlusion onto a game character's model ensures consistent shading without real-time ray tracing, improving both visual quality and efficiency.
