D3DFVF_TEXCOORDSIZEN
Constructs bit patterns that are used to identify texture coordinate formats within a FVF description. The results of these macros can be combined within a FVF description by using the OR operator.
#define D3DFVF_TEXCOORDSIZEN(CoordIndex)
#define D3DFVF_TEXCOORDSIZE1(CoordIndex) (D3DFVF_TEXTUREFORMAT1 << (CoordIndex*2 + 16))
#define D3DFVF_TEXCOORDSIZE2(CoordIndex) (D3DFVF_TEXTUREFORMAT2)
#define D3DFVF_TEXCOORDSIZE3(CoordIndex) (D3DFVF_TEXTUREFORMAT3 << (CoordIndex*2 + 16))
#define D3DFVF_TEXCOORDSIZE4(CoordIndex) (D3DFVF_TEXTUREFORMAT4 << (CoordIndex*2 + 16))
Parameters
Parameter | Description |
---|---|
CoordIndex |
Value that identifies the texture coordinate set at which the texture coordinate size (1-, 2-, 3-, or 4Dimensional) applies. |
Remarks
The D3DFVF_TEXCOORDSIZEN macros use the following constants.
#define D3DFVF_TEXTUREFORMAT1 3 // one floating point value
#define D3DFVF_TEXTUREFORMAT2 0 // two floating point values
#define D3DFVF_TEXTUREFORMAT3 1 // three floating point values
#define D3DFVF_TEXTUREFORMAT4 2 // four floating point values
The following FVF 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 = D3DFVF_XYZ | D3DFVF_NORMAL | D3DFVF_DIFFUSE |
D3DFVF_SPECULAR | D3DFVF_TEX2 |
D3DFVF_TEXCOORDSIZE1(0) | // Uses 1D texture coordinates for
// texture coordinate set 1 (index 0).
D3DFVF_TEXCOORDSIZE2(1); // And 2D texture coordinates for
// texture coordinate set 2 (index 1).
