UV mapping is the 3D modeling process of making a 2D image representation of a 3D model’s surface. It is created by unwrapping the object itself and laying a texture of the 2d bits. It can control the way the texture wraps on the 3D model. Texturing is how flat images are applied to 3D objects — also known as wrapping. Texturing is the process of applying both colours and textures to to this 2D mesh, ready to be wrapped over the plain 3D model.For more complex models it’s not uncommon to use what’s called an “unwrap” — which is simply a map that shows how a 2D map will wrap around a 3D model.Textures are never applied directly to a 3D model however — always a UV map!
