UV Mapping
UV mapping is a 3D modeling technique that projects a 2D image texture onto a 3D model's surface by assigning coordinates (U and V axes) to vertices, enabling realistic texturing and material application. It involves unwrapping the 3D mesh into a flat 2D layout, allowing artists to paint or apply textures accurately without distortion. This process is essential in computer graphics for creating detailed surfaces in games, animations, and visual effects.
Developers should learn UV mapping when working in 3D graphics pipelines, such as game development, animation, or VR/AR projects, to apply textures efficiently and achieve high-quality visual results. It is crucial for optimizing performance by reducing texture stretching and seams, and it enables advanced techniques like normal mapping and PBR workflows. Use cases include character modeling, environment design, and product visualization where realistic materials are required.
