Abstract: Firstly,the principle of pixel shading and modern graphics hardware architectures are described.Secondly,a technique on how to analyze and solve rendering problems with pixel shading is proposed,along with the methods on how to construct texture representation of lighting parameters.Finally,the paper presents experimental results with different levels of hardware acceleration based-on real-time bump mapping rendering.
