The Mathematical Methods in the Normal Mapping Technology of 3D Games
Zhang Yun-yuan · Computer Knowledge and Technology · 2011
3D games have become mainstream products of the computer games.Truly reflecting the characters of the game roles and per forming the bump effects of the scenes are the important parts in the development of a realistic game.By using the normal mapping technol ogy,it can still ensure the better performance of the bump effect without increasing the model grid and remain the good bump effect after changes in perspective.In this paper,it will discuss the basic mathematical methods of the normal bump mapping technology used to show the dump effects in the process of computer games development in terms of following parts,the construction of bump mapping,tangent space and tangent vec tor.These mathematical methods will provide the mathematical solutions of the normal mapping technology in the engine programs design during the game development.
