D3D11_SO_DECLARATION_ENTRY Structure

Description of a vertex element in a vertex buffer in an output slot.

Syntax

typedef struct D3D11_SO_DECLARATION_ENTRY {
    UINT Stream;
    LPCSTR SemanticName;
    UINT SemanticIndex;
    BYTE StartComponent;
    BYTE ComponentCount;
    BYTE OutputSlot;
} D3D11_SO_DECLARATION_ENTRY;  

Members

Stream
Zero-based, stream number.

SemanticName
Type of output element; possible values include: “POSITION”, “NORMAL”, or “TEXCOORD0”. Note that if SemanticName is NULL then ComponentCount can be greater than 4 and the described entry will be a gap in the stream out where no data will be written.

SemanticIndex
Output element’s zero-based index. Should be used if, for example, you have more than one texture coordinate stored in each vertex.

StartComponent
Which component of the entry to begin writing out to. Valid values are 0 to 3. For example, if you only wish to output to the y and z components of a position, then StartComponent should be 1 and ComponentCount should be 2.

ComponentCount
The number of components of the entry to write out to. Valid values are 1 to 4. For example, if you only wish to output to the y and z components of a position, then StartComponent should be 1 and ComponentCount should be 2. Note that if SemanticName is NULL then ComponentCount can be greater than 4 and the described entry will be a gap in the stream out where no data will be written.

OutputSlot
The associated stream output buffer that is bound to the pipeline (see ID3D11DeviceContext::SOSetTargets). The valid range for OutputSlot is 0 to 3.
