Could you please tell us more detailed what your a looking for? In general a disassembled D3D10 shader doesn’t look that different from a D3D9 shader.
Anyway all you can do with a disassembled D3D10 shader is to look at it or let it parse from another program. But most of the information you can get from this can be obtained more easily with the shader reflection interfaces.
I know it but for my project I need to know how directX10 compile the geometry shader that is kind different from vertex and pixel shader (it has an inout list for example).
What I need is an fx file (one of the fx shader in the october SDK for example) and its compilation with fxc10 (fxc10 /T fx4_0 filename)
In that way I can see in assembly what it does. I've october SDK but fxc10 need directX10 installed and actually I can't install Vista on my machine to test personally.
Thank you
Here we go. The FX file was taken from Tutorial 13.
