D3D12_ROOT_CONSTANTS structure (d3d12.h)
Describes constants inline in the root signature that appear in shaders as one constant buffer.
Syntax
typedef struct D3D12_ROOT_CONSTANTS {
UINT ShaderRegister;
UINT RegisterSpace;
UINT Num32BitValues;
} D3D12_ROOT_CONSTANTS;
Members
ShaderRegister
The shader register.
RegisterSpace
The register space.
Num32BitValues
The number of constants that occupy a single shader slot (these constants appear like a single constant buffer). All constants occupy a single root signature bind slot.
Remarks
Refer to Resource Binding in HLSL for more information on shader registers and spaces.
D3D12_ROOT_CONSTANTS is the data type of the Constants member of D3D12_ROOT_PARAMETER. Use a D3D12_ROOT_CONSTANTS when you set D3D12_ROOT_PARAMETER's SlotType field to the D3D12_ROOT_PARAMETER_TYPE_32BIT_CONSTANTS member of D3D12_ROOT_PARAMETER_TYPE.
