D3DFVF_TEXCOORDSIZEn

The D3DFVF_TEXCOORDSIZEn macros construct bit patterns that are used to identify texture coordinate formats within a flexible vertex format description. The results of these macros can be combined within a flexible vertex format description by using the OR operator.

D3DFVF_TEXCOORDSIZE1(CoordIndex) (D3DFVF_TEXTUREFORMAT1 << (CoordIndex*2 + 16)) 
D3DFVF_TEXCOORDSIZE2(CoordIndex) (D3DFVF_TEXTUREFORMAT2) 
D3DFVF_TEXCOORDSIZE3(CoordIndex) (D3DFVF_TEXTUREFORMAT3 << (CoordIndex*2 + 16)) 
D3DFVF_TEXCOORDSIZE4(CoordIndex) (D3DFVF_TEXTUREFORMAT4 << (CoordIndex*2 + 16)) 

Parameters

CoordIndex

Value identifying the texture coordinate set at which the texture coordinate size (1-, 2-, 3-, or 4-dimensional) applies.

Remarks

The following flexible vertex format description identifies a vertex format that has a position, a normal, diffuse and specular colors, and two sets of texture coordinates. The first set of texture coordinates includes a single element, and the second set includes two elements:

DWORD dwFVF;
dwFVF = D3DFVF_XYZ | D3DFVF_NORMAL | D3DFVF_DIFFUSE | D3DFVF_SPECULAR |
        D3DFVF_TEXCOORDSIZE1(0) |  \\ Uses 1-D texture coordinates for texture coordinate set 1 (index 0)
        D3DFVF_TEXCOORDSIZE2(1);   \\ And 2-D texture coordinates for texture coordinate set 2 (index 1).
