D3DDECLMETHOD

From the MS Learn page.

Name	Value	Comments
D3DDECLMETHOD_DEFAULT	0	Default value. The tessellator copies the vertex data (spline data for patches) as is, with no additional calculations. When the tessellator is used, this element is interpolated. Otherwise vertex data is copied into the input register. The input and output type can be any value.
D3DDECLMETHOD_PARTIALU	1	Computes the tangent at a point on the rectangle or triangle patch in the U direction. The input type can be D3DDECLTYPE_FLOAT3, D3DDECLTYPE_FLOAT4, D3DDECLTYPE_D3DCOLOR, D3DDECLTYPE_UBYTE4, D3DDECLTYPE_SHORT4. The output type is always D3DDECLTYPE_FLOAT3.
D3DDECLMETHOD_PARTIALV	2	Computes the tangent at a point on the rectangle or triangle patch in the V direction. The input type can be D3DDECLTYPE_FLOAT3, D3DDECLTYPE_FLOAT4, D3DDECLTYPE_D3DCOLOR, D3DDECLTYPE_UBYTE4, or D3DDECLTYPE_SHORT4. The output type is always D3DDECLTYPE_FLOAT3.
D3DDECLMETHOD_CROSSUV	3	Computes the normal at a point on the rectangle or triangle patch by taking the cross product of the two tangents. The input type can be D3DDECLTYPE_FLOAT[43], D3DDECLTYPE_D3DCOLOR, D3DDECLTYPE_UBYTE4, or D3DDECLTYPE_SHORT4. The output type is always D3DDECLTYPE_FLOAT3.
D3DDECLMETHOD_UV	4	Copy out the U, V values at a point on the rectangle or triangle patch. This results in a 2D float. The input type must be set to D3DDECLTYPE_UNUSED. The output data type is always D3DDECLTYPE_FLOAT2. The input stream and offset are also unused (but must be set to 0).
D3DDECLMETHOD_LOOKUP	5	Look up a displacement map. The input type can be D3DDECLTYPE_FLOAT2, D3DDECLTYPE_FLOAT3, or D3DDECLTYPE_FLOAT4. Only the .x and .y components are used for the texture map lookup. The output type is always D3DDECLTYPE_FLOAT1. The device must support displacement mapping. This constant is supported only by the programmable pipeline on N-patch data, if N-patches are enabled.
D3DDECLMETHOD_LOOKUPPRESAMPLED	6	Look up a presampled displacement map. The input type must be set to D3DDECLTYPE_UNUSED. The stream index and the stream offset must be set to 0. The output type for this operation is always D3DDECLTYPE_FLOAT1. The device must support displacement mapping. This constant is supported only by the programmable pipeline on N-patch data, if N-patches are enabled.

D3DDECLUSAGE

Name	Value	Comments
D3DDECLUSAGE_POSITION	0	Position data.
D3DDECLUSAGE_BLENDWEIGHT	1	Blending weight data.
D3DDECLUSAGE_BLENDINDICES	2	Blending indices data.

D3DDECLUSAGE_PSIZE	4	Point size data.
D3DDECLUSAGE_TEXCOORD	5	Texture coordinate data.
D3DDECLUSAGE_TANGENT	6	Vertex tangent data.
D3DDECLUSAGE_BINORMAL	7	Vertex binormal data.
D3DDECLUSAGE_TESSFACTOR	8	Single positive floating-point value. Use D3DDECLUSAGE_TESSFACTOR with a usage index of 0 to specify a tessellation factor used in the tessellation unit to control the rate of tessellation.
D3DDECLUSAGE_COLOR	10	Vertex data contains diffuse or specular color.
D3DDECLUSAGE_FOG	11	Vertex data contains fog data.
