-(The following is from [http://en.wikipedia.org/wiki/Bump_mapping The Wikipedia bump mapping page])
-Bump mapping is a technique where at each pixel, a perturbation to the surface normal of the object being rendered is looked up in a texture map and applied before the illumination calculation is done. The result is a richer, more detailed surface representation that more closely resembles the details inherent in the natural world.
-This is an example of Bump mapping in Half Life 2

-Bump mapping has been appiled to the brick material to give it an almost 3D effect on the suface and grooves.
-Models in the source engine can do the same. Bump mapping can be applied to a range of materials such as water and clothing or to add texture to monsters. Antlions on Half Life 2 use bump mapping for their shell texture giving them a more natural insect-like effect.
