摘　　要：传统的纹理贴图技术常常只能表现出物体表面的色彩变化,不能对粗糙表面上凹凸不平的细节进行表达,以体现出深度感。所论述的视差贴图技术很好地解决这个问题,它不仅可以实现物体表面凹凸不平的效果,还可以产生因自遮挡导致的自阴影效果以及运动视差,使场景更具真实感。Traditional texture mapping can only display the color of surfaces,it can't display the uneven details of rough surfaces,so that it can't express depth.Parallax mapping technology described can be used to solve this problem,it can not only implement the uneven visual effect of object surface,but also display motion-parallax and shadows due to self-occlusion,which makes the scene more realistic.

关 键 词：法线贴图 运动视差 自遮挡 软阴影
