DirectX/HLSL 错误 PS2.0
我收到此错误
着色器在依赖链中使用纹理寻址操作，该依赖链对于目标着色器模型 (ps_2_0) 来说过于复杂，无法处理。
since i have added this line to my pixelshader:
float Gauss[NUMWT] = { 5.052271056506993e-15, 9.134720359492243e-12, 6.07588281731559e-9, 0.0000014867195067797903, 0.00013383022504883334, 0.004431848388225362, 0.053990966224306644, 0.2419707232244606, 0.39894227826685835, 0.2419707232244606, 0.053990966224306644, 0.004431848388225362, 0.00013383022504883334, 0.0000014867195067797903, 6.07588281731559e-9, 9.134720359492243e-12, 5.052271056506993e-15 };
这个数组太大了吗？
i am getting this error
Shader uses texture addressing operations in a dependency chain that is too complex for the target shader model (ps_2_0) to handle.

float Gauss[NUMWT] = { 5.052271056506993e-15, 9.134720359492243e-12, 6.07588281731559e-9, 0.0000014867195067797903, 0.00013383022504883334, 0.004431848388225362, 0.053990966224306644, 0.2419707232244606, 0.39894227826685835, 0.2419707232244606, 0.053990966224306644, 0.004431848388225362, 0.00013383022504883334, 0.0000014867195067797903, 6.07588281731559e-9, 9.134720359492243e-12, 5.052271056506993e-15 };
is this array too big?

这一点
可能是问题所在的关键。错误没有附带行号和字符号吗？
在复杂路径（可能是分支）内寻找从纹理采样或计算位置的点。
This bit
is probably the key to where your problem is. Did the error not come with a line and character number?
Look for spots where you're sampling from textures or calculating the position, within complex paths (possibly branching).
做了一个快速测试，数组使用 ps_2_0 （将 NUMWT 定义为 17）对我来说编译得很好，所以我猜你的错误在其他地方。
另外，为什么它在处理如此“小”的数组时会有任何问题呢？纹理要大得多。
Did a quick test and the array compiles fine for me using ps_2_0 (defining NUMWT as 17) so I guess your error is somewhere else.
Also why should it have any issues handling such "small" arrays? textures are far bigger.
