D3D12_ROOT_PARAMETER1 structure (d3d12.h)

Describes the slot of a root signature version 1.1.

Syntax

typedef struct D3D12_ROOT_PARAMETER1 {
  D3D12_ROOT_PARAMETER_TYPE ParameterType;
  union {
    D3D12_ROOT_DESCRIPTOR_TABLE1 DescriptorTable;
    D3D12_ROOT_CONSTANTS         Constants;
    D3D12_ROOT_DESCRIPTOR1       Descriptor;
  };
  D3D12_SHADER_VISIBILITY   ShaderVisibility;
} D3D12_ROOT_PARAMETER1;

Members

ParameterType

A D3D12_ROOT_PARAMETER_TYPE-typed value that specifies the type of root signature slot. This member determines which type to use in the union below.

DescriptorTable

A D3D12_ROOT_DESCRIPTOR_TABLE1 structure that describes the layout of a descriptor table as a collection of descriptor ranges that appear one after the other in a descriptor heap.

Constants

A D3D12_ROOT_CONSTANTS structure that describes constants inline in the root signature that appear in shaders as one constant buffer.

Descriptor

A D3D12_ROOT_DESCRIPTOR1 structure that describes descriptors inline in the root signature that appear in shaders.

ShaderVisibility

A D3D12_SHADER_VISIBILITY-typed value that specifies the shaders that can access the contents of the root signature slot.

Remarks

Use this structure with the D3D12_ROOT_SIGNATURE_DESC1 structure.

Refer to the helper structure CD3DX12_ROOT_PARAMETER1.
