A normal map is an image that stores a direction at each pixel. These directions are called normals. The red, green, and blue channels of the image are used to control the direction of each pixel's normal. A normal map is commonly used to fake high-resolution details on a low-resolution model.
Tutorial 13 : Normal Mapping

Today we will talk about normal mapping. Since Tutorial 8 : Basic shading, you know how to get decent shading using triangle normals. One caveat is that until now, we only had one normal per...

Textures often called Bump Maps, or Normal Maps are used to simulate three-dimensional details on a two-dimensional surface by manipulating its lighting. Note:Static props using bump maps can not be lit per-vertex, except in . Note:Bump maps cannot be used on decal textures, except in .
