凹凸贴图
Comparable with the Normal Mapping effect, a bump
map can be used to affect surface Normals and simulate minor surface irregularities and structures. A bump map
contains only grayscale values and does not include information about a surface’s angles. These are derived
from the input’s gradients at render time. A Normal Map bears the advantage that it contains RGB values and
these precisely define the surface Normal’s direction. 与法线贴图效果相当的是，凹凸贴图可以用来影响表面法线，模拟表面微小的不规则性和结构。凹凸贴图只包含灰度值，不包含表面角度的信息。这些是从渲染时的输入梯度派生出来的。法线贴图的优点是它包含 RGB 值，这些值精确地定义了表面法线的方向
By manipulating the surface Normals, the shading of the object surface will be modified. Minor irregularities such as scratches, pores or wood grain can be simulated without affecting the object’s geometry. Since this is only a shading effect, the object’s geometry will not be modified. Brighter regions will appear raised and darker areas sunken.
通过操作表面法线，物体表面的阴影将得到修改。轻微的不规则，如划痕，孔或木纹可以模拟而不影响对象的几何形状。由于这只是一个阴影效果，对象的几何体将不会被修改。明亮的区域会出现凸起，暗色的区域会出现凹陷。
