@coopp - as you're looking in to the reflection stuff at the moment you may be able to answer whether or not this is possible.
I think the SemanticName is available as part of the _D3D12_SIGNATURE_PARAMETER_DESC
typedef struct _D3D12_SIGNATURE_PARAMETER_DESC
{
LPCSTR SemanticName; // Name of the semantic
UINT SemanticIndex; // Index of the semantic
UINT Register; // Number of member variables
D3D_NAME SystemValueType;// A predefined system value, or D3D_NAME_UNDEFINED if not applicable
D3D_REGISTER_COMPONENT_TYPE ComponentType; // Scalar type (e.g. uint, float, etc.)
BYTE Mask; // Mask to indicate which components of the register
// are used (combination of D3D10_COMPONENT_MASK values)
BYTE ReadWriteMask; // Mask to indicate whether a given component is
// never written (if this is an output signature) or
// always read (if this is an input signature).
// (combination of D3D_MASK_* values)
UINT Stream; // Stream index
D3D_MIN_PRECISION MinPrecision; // Minimum desired interpolation precision
} D3D12_SIGNATURE_PARAMETER_DESC;
The question is about obtaining the member name (eg mPos
) as opposed to the semantic name (eg POSITION
).
OH! I misread the question. I'll look some more to see if that information can be retrieved.
I do not see a way to get this information. Looks like there are ways to inspect buffers/resources etc and get their names but not the names of members on these inputs.
I am writing a code generator based on D3D12 shader reflection data. Given a simple vertex shader:
I can use
ID3D12ShaderReflection::GetInputParameterDesc
to get the type and semantic for each member of VertexIn, as well as the register it is mapped to. However, I would like to retrieve the names of the VertexIn members (i.e. "mPos" and "mColor") for my generated code. Is there a way to do this?
