Normal Mapping Vs Bump Mapping
Question
Hank, my man, can you explain to me the difference between 'normal mapping' and 'bump mapping'? As far as i know, bump mapping makes a object look like a high poly model (while it is not). I watched the Chronicles of Riddick tech overview, in wich the developer was talking about normal mapping. To be short, it mentioned how normal mapping makes a object look like a high poly model.

Thanks in advance...
Answer
Normal mapping is a type of bump mapping that involves a normal map, an image that contains an XYZ direction vector (i.e. normal vector) at each pixel to be used in polygon surface lighting calculations. Some types of bump mapping are done without a normal map. With all types of bump mapping, the goal is to increase surface lighting detail without adding more polygons or vertices.
