摘　　要：多级纹理(Mipmap)技术是目前解决纹理分辨率与视点距离关系的最有效途径,但是不能有效表现纹理的凹凸感.凹凸映射(Bump Mapping)能非常逼真地再现物体表面凹凸细节,但是计算量大.因此对Mipmap算法进行有效改进,有效地结合了凹凸映射的优势,以很少量的计算量,有效地提高了纹理的凹凸感.Mipmap is a best solution to handle the relation between texture resolution and viewpoint distance, but it cannot provide enough details of the objects surface. Bump mapping can give a lifelike feeling, unfortunately it has large computational effort. This paper improves the original Mipmap algorithm effectively. The result showed that it can reduce the computation effort and give a better demonstration of textures.
