D3DVSD_REG

Binds a single vertex register to a vertex element from the vertex stream.

D3DVSD_REG( _VertexRegister, _Type ) \
          (D3DVSD_MAKETOKENTYPE(D3DVSD_TOKEN_STREAMDATA) | \
          ((_Type) << D3DVSD_DATATYPESHIFT) | (_VertexRegister))

Parameters

_VertexRegister

Address of the vertex register. Possible values range from 0 through 16. For the fixed function pipeline, the input registers have the following fixed mapping.

_Type

Specifies the dimensionality and arithmetic data type. The following values are defined.

D3DVSDT_D3DCOLOR

4-D packed unsigned bytes mapped to 0.0 to 1.0 range. In double word format this is ARGB, or in byte ordering it would be B, G, R, A.

D3DVSDT_FLOAT1

1-D float expanded to (value, 0.0, 0.0, 1.0)

D3DVSDT_FLOAT2

2-D float expanded to (value, value, 0.0, 1.0)

D3DVSDT_FLOAT3

3-D float expanded to (value, value, value, 1.0)

D3DVSDT_FLOAT4

4-D float.

D3DVSDT_SHORT2

2-D signed short expanded to (value, value, 0.0, 1.0)

D3DVSDT_SHORT4

4-D signed short

D3DVSDT_UBYTE4

4-D unsigned byte. In double word format this is ABGR, or in byte ordering it would be R, G, B, A.
