What is UV Mapping
 

I'd just like to know what it is, cause I need to learn for a school project.

UV Mapping is:

Is a way of saying u,v texture coordinates, which are positions within an ideal image (1-by-1). These typically connect to points in a 3D mesh, to position an image texture on the mesh. Like virtual tacks, they pin an exact spot on an image to a point on an object's surface. Between the tacks, renderers will stretch the image smoothly. This is what is referred to as UV mapping. UV mapping is used extensively in real-time environments, like OpenGL and typical 3D games, where hardware-based shading routines can be re-used for texture interpolation. It is also useful on another level with NURBS, and other parametric surfaces, which have inherent u,v parameters defined continuously along the entire surface.

Oh. That sounds cool. Thanx a lot. Now I'll learn how to do it.
