Texture mapping

Definition

Texture mapping is a computer graphics technique that involves applying a 2D image, known as a texture, to a 3D model's surface to create detailed and realistic visuals. This technique enhances the appearance of objects by providing surface details such as color, patterns, and imperfections, significantly improving the depth and realism of computer-generated imagery. It became particularly important in the evolution of animation as it allowed for more complex and visually appealing scenes.
