Members
Format
A DXGI_FORMAT-typed value that specifies the viewing format. See remarks.
ViewDimension
A D3D12_SRV_DIMENSION-typed value that specifies the resource type of the view. This type is the same as the resource type of the underlying resource. This member also determines which _SRV to use in the union below.
Shader4ComponentMapping
A value, constructed using the D3D12_ENCODE_SHADER_4_COMPONENT_MAPPING macro. The D3D12_SHADER_COMPONENT_MAPPING enumeration specifies what values from memory should be returned when the texture is accessed in a shader via this shader resource view (SRV). For example, it can route component 1 (green) from memory, or the constant 0, into component 2 (.b) of the value given to the shader.
Buffer
A D3D12_BUFFER_SRV structure that views the resource as a buffer.
Texture1D
A D3D12_TEX1D_SRV structure that views the resource as a 1D texture.
Texture1DArray
A D3D12_TEX1D_ARRAY_SRV structure that views the resource as a 1D-texture array.
Texture2D
A D3D12_TEX2D_SRV structure that views the resource as a 2D-texture.
Texture2DArray
A D3D12_TEX2D_ARRAY_SRV structure that views the resource as a 2D-texture array.
Texture2DMS
A D3D12_TEX2DMS_SRV structure that views the resource as a 2D-multisampled texture.
Texture2DMSArray
A D3D12_TEX2DMS_ARRAY_SRV structure that views the resource as a 2D-multisampled-texture array.
Texture3D
A D3D12_TEX3D_SRV structure that views the resource as a 3D texture.
TextureCube
A D3D12_TEXCUBE_SRV structure that views the resource as a 3D-cube texture.
TextureCubeArray
A D3D12_TEXCUBE_ARRAY_SRV structure that views the resource as a 3D-cube-texture array.
RaytracingAccelerationStructure
A D3D12_RAYTRACING_ACCELERATION_STRUCTURE_SRV structure that views the resource as a raytracing acceleration structure.
Remarks
A view is a format-specific way to look at the data in a resource. The view determines what data to look at, and how it is cast when read.
When viewing a resource, the resource-view description must specify a typed format, that is compatible with the resource format. So that means that you can't create a resource-view description using any format with _TYPELESS in the name. You can however view a typeless resource by specifying a typed format for the view. For example, a DXGI_FORMAT_R32G32B32_TYPELESS resource can be viewed with one of these typed formats: DXGI_FORMAT_R32G32B32_FLOAT, DXGI_FORMAT_R32G32B32_UINT, and DXGI_FORMAT_R32G32B32_SINT, since these typed formats are compatible with the typeless resource.
Create a shader-resource-view description by calling ID3D12Device::CreateShaderResourceView.
