How to set Sampler State properties used in a pixel shader for Direct2D Custom Effect? RRS feed

  • Question

  • I want to create a custom Direct2D effect with reference to this sample


    And since i started write pixel shader code, i find

    SamplerState S  : register(s0)
     Filter = MIN_MAG_MIP_POINT;
     AddressU = Wrap;
     AddressV = Wrap;

    When the pixel shader is executing, the Filter Property, Address Properties are not the one i specified in hlsl code?

    Any idea how to change these settings?

    I tried PSSetSamplerState over the ID3D11DeviceContext, seems not working unless i missed something?

    NOTE: If I ask for code, please provide something that I can drop directly into a project and run (including XAML), or an actual application project. I'm trying to help a lot of people, so I don't have time to figure out weird snippets with undefined objects and unknown namespaces.

  • I think you should set the sampler state in c++ code but not the hlsl code.

    // Create the sampler state
    	D3D11_SAMPLER_DESC samplerDesc;
    	ZeroMemory(&samplerDesc, sizeof(samplerDesc));
    	samplerDesc.Filter = D3D11_FILTER_MIN_MAG_LINEAR_MIP_POINT;
    	samplerDesc.AddressU = D3D11_TEXTURE_ADDRESS_BORDER;
    	samplerDesc.AddressV = D3D11_TEXTURE_ADDRESS_BORDER;
    	samplerDesc.AddressW = D3D11_TEXTURE_ADDRESS_BORDER;
