它所做的事情只是为了使贴图产生扭曲而修改贴图坐标。
All that it does is modify texture coordinates in order to warp a texture mapped image.
这个新的贴图坐标被用来索引一般的材质贴图和其他用在表面上的贴图。
The new texture coordinate is used to index a regular texture map and any other maps applied to the surface.
原始的材质贴图坐标和高度数据已经在切线空间中了，因此视向量最好也能如此。
The original texture coordinate and height values are already represented in tangent space, so the eye vector must be as well.
通过偏移所有这样的贴图坐标，表面上的较高的地方会相对眼睛被移远，而低的地方被移近。
By offsetting all the texture coordinates individually, high areas of the surface would shift away from the eye and low areas of the surface would shift toward the eye.
视差贴图技术的过程有以下要求：对每个像素都做处理中，一个贴图坐标能被多张贴图使用，并且能做一些偏移。
The process of parallax mapping requires that, for each pixel drawn, a texture coordinate, used to index one or more texture maps, be corrected by some displacement.
