D3D12_SHADER_VARIABLE_DESC structure (d3d12shader.h)
Describes a shader variable.
Syntax
typedef struct _D3D12_SHADER_VARIABLE_DESC {
LPCSTR Name;
UINT StartOffset;
UINT Size;
UINT uFlags;
LPVOID DefaultValue;
UINT StartTexture;
UINT TextureSize;
UINT StartSampler;
UINT SamplerSize;
} D3D12_SHADER_VARIABLE_DESC;
Members
Name
The variable name.
StartOffset
Offset from the start of the parent structure to the beginning of the variable.
Size
Size of the variable (in bytes).
uFlags
A combination of D3D_SHADER_VARIABLE_FLAGS-typed values that are combined by using a bitwise-OR operation. The resulting value identifies shader-variable properties.
DefaultValue
The default value for initializing the variable. Emits default values for reflection.
StartTexture
Offset from the start of the variable to the beginning of the texture.
TextureSize
The size of the texture, in bytes.
StartSampler
Offset from the start of the variable to the beginning of the sampler.
SamplerSize
The size of the sampler, in bytes.
Remarks
Get a shader-variable description using reflection by calling ID3D12ShaderReflectionVariable::GetDesc.
