在研究HLSL时编译一个demo出现了error X3539的问题
解决方案
将代码中的ps_1_1 改为ps_2_0
PixelShader = compile ps_1_1 PS();
或者是在D3DXCompileShaderFromFile函数中将对应的ps_1_1改为ps_2_0
//create pixel shader
ID3DXBuffer* codeBuffer = 0;
ID3DXBuffer* errorBuffer = 0;
HRESULT hr = D3DXCompileShaderFromFile("ps.txt",
0,
0,
"PS_Main", // entry point function name
"ps_2_0", //ps_1_1 is error X3539
D3DXSHADER_DEBUG,
&codeBuffer,
&errorBuffer,
&pixelConstTable);
最后渲染出来的结果
