black and white map

基本解释

Finally, use Color Dodge at 50% opacity (or another you think is better) as the layer multiplier. Done. Now you have black, white and grey on your bump map.
最后，以50%透明度的颜色分离叠加方式叠加。现在你有了黑白灰的凹凸贴图了。
Converting a black and white image can be done in Photoshop using the Nvidia Photoshop plugin, this allows you to paint a black and white image and encode it into a normal map.
转换一张黑白图像可以通过在PS中使用Nvidia的PS插件来实现，这允许你绘制一行黑白图像并将其编码为一张法线贴图。
However, this shouldn't be surprising, because even simple visual mappings -- map a 1 to a black square and a 0 to a white square -- can generate quite beautiful and intricate patterns.
不过，这并不意外，因为即使简单的直观映射——将 1 映射为黑方块，0 映射为白方块——也可以生成漂亮和复杂的样式。
