摘　　要：MipMap是目前应用最为广泛的纹理映射技术之一,其优点是速度快,但很难实现物体的凹凸感.采用MipMap技术和光线跟踪技术相结合,提出一种改进的真实感纹理贴图技术.实验证明,该算法更加真实地模拟物体表面的凹凸感,从而取得更加真实的纹理贴图效果.MipMap technique is one of the most popular texture mapping methods.It has the advantage of quick texture rendering,but it has the disadvantage as well,that it,the bump on the objects is not realistic.A new method based on MipMap algorithm and racy tracing is put forward in the paper.It is provided that this method improve the bump texture realistically,thus improving the texture rendering effects.
