In computer graphics, wrapping is the process of limiting a position to an area.
A good example of wrapping is wallpaper, a single pattern repeated indefinitely over a wall.
Wrapping is used in 3D computer graphics to repeat a texture over a polygon, eliminating the need for large textures or multiple polygons.
To wrap a position x to an area of width w, calculate the value
For computational purposes the wrapped value x' of x can be expressed as where
