I've got a question about SetPixelShader, how does it affect the screen? for example when I call it before drawing something, does it affect on all the screen? and does it affect on the next drawing calls? I mean how can I disable the pixel shader for something and enable it again? is there anything like SetPixelShader(NULL) (just like SetVertexShader(NULL))? thanks... visit our site galaxyroad.com which soon will have english contents too.

The shader will affect every pixel that is drawn while that shader is valid. I haven't used pixel shaders in this fashion yet, but setting it to NULL sounds like the proper approach. One way to find out is to do a simple test...
