To complete the pixel shader, we just need to convert the normal into the working model's tangent space and scale it to the 0..255 range to be stored in a bitmap, as shown in Listing 22-8.Example 22-8. Converting the Normal to Tangent SpaceCopy float3 normalTS; normalTS.x = dot...
The recognition approach, based on the computation of a difference map resulting from the comparison of normal maps, is simple yet fast and accurate. A weighting mask, automatically generated for each subject using a set of expression variations, improves the robustness to a broad range of facial...
Unity为了某些原因把上述过程进行了封装,也就是说上述代码在Unity里可以这么做:把法线纹理的“Texture Type”设置成“Normal Map”,在代码中使用UnpackNormal函数得到法线方向。这其中的原因,我猜想一方面是为了方便它对不同平台做优化和调整,一方面是为了解析不同格式的法线纹理。
注意,这里并没有把法线纹理的“Texture Type”设置成“Normal Map”。上述方法是可以得到正确的法线方向的。 Unity为了某些原因把上述过程进行了封装,也就是说上述代码在Unity里可以这么做:把法线纹理的“Texture Type”设置成“Normal Map”,在代码中使用UnpackNormal函数得到法线方向。这其中的原因,我猜想一方面是为了...
