This is where things really get interesting. Texture mapping is the key to amazing graphics in 3D games. A very common analogy used for texture mapping is the
wrapping of birthday presents. When you wrap the sheet around the gift, the paper takes on the form of the gift. That’s pretty much how texture mapping works. You take a flat image, a pattern, or text (the wrapping paper) and wrap it around a shape or an object you have created or imported.
