102	Normal Mapping	patrick	nobody	"Normal maps make the surface of a game model look much more detailed and impressive. This detail is displayed in real time: the images in the article are screengrabs, not renders. To create a normal map, a 3D software package samples the directions in which the surfaces of a detailed model (a higher-resolution version of the in-game object) face, storing the information as coloured pixels. The map is then applied to the lower-resolution object, passing information about the hi-res model to the lighting calculations.
