问题
I'm having a number of isses with HLSL and Pix.
1) Can you in HLSL 3, declare a Pixel shader alone without a Vertex Shader? If not, what can I do to get around this?
2) Why does Pix skip code? I have a reasonably long shader method but Pix seems to stop me from debugging until half way through the method and then skips the rest of the block. I set Pix to gather information when F12 is hit and check the DISABLE D3DX analysis checkbox. I have to do this because I'm using XNA.
3) Can I debug the shader as the experiment is being run?
Cheers,
