Hey,

Just want to check with you guys:

IIRC, any vertex after applying projection matrix, should report it pixel location at x, and y component right?

so if you have the simplest pixel shader like the following, each of your rasterized pixel should report its screen location in it's x, and y component:

float4 main( float4 f4ProjPos : SV_POSITION ) : SV_Target
{
    return f4ProjPos;
}

I have this simple case setup (I render a unit length cube), and after I run it with visual studio graphics debug, I found out there are decent number of pixel whose value is not pixel location (1-8 offset).

I am super confused with this result, so I am here hoping you guys could tell me what I have missed? Is the interpolation modifier I have to specifically set? or there are any fundamental HW stuff prohibit this?

Thanks
