Texturing in computer graphics refers to the process of applying images, patterns, or colors to 3D models to enhance their visual detail. This technique helps create realistic surfaces, such as wood, metal, or skin, by wrapping a 2D image, known as a texture map, around the 3D object. Textures can also include additional information, like bump maps or normal maps, which simulate surface irregularities without altering the model's geometry. This adds depth and realism, making the final render more visually appealing in applications like video games, movies, and virtual reality.
