Any more info on D2D Custom Effect ?

    Question

  • float4 main(
        float4 pos      : SV_POSITION,
        float4 posScene : SCENE_POSITION,
        float4 uv0      : TEXCOORD0
        ) : SV_Target
    {
    }

    This is a Pixel Shader  in sample custom d2d effect, is there a default Vertex Shader, and what does the parameters mean?

    The uv0(TEXCOORD0) seems not from 0.0 to 1.0 ?

  • Hello,

    I apologize but unfortunately I don't really know what you are asking. Direct2D can use its vertex shaders to continue to accumulate shader constant data and then issue one Direct3D Draw call for a large number of Direct2D Draw calls.

    Does this answer your question?

    Thanks,

    James
