D3DTEXTURETRANSFORMFLAGS

The D3DTEXTURETRANSFORMFLAGS enumerated type defines values used with the D3DTSS_TEXTURETRANSFORMFLAGS texture-stage state.

typedef enum _D3DTEXTURETRANSFORMFLAGS {
    D3DTTFF_DISABLE         = 0,   
    D3DTTFF_COUNT1          = 1,   
    D3DTTFF_COUNT2          = 2,   
    D3DTTFF_COUNT3          = 3,   
    D3DTTFF_COUNT4          = 4,   
    D3DTTFF_PROJECTED       = 256, 
    D3DTTFF_FORCE_DWORD     = 0x7fffffff, 
} D3DTEXTURETRANSFORMFLAGS;

D3DTTFF_DISABLE

Texture coordinates are passed directly to the rasterizer.

D3DTTFF_COUNT1

The rasterizer should expect 1-D texture coordinates.

D3DTTFF_COUNT2

The rasterizer should expect 2-D texture coordinates.

D3DTTFF_COUNT3

The rasterizer should expect 3-D texture coordinates.

D3DTTFF_COUNT4

The rasterizer should expect 4-D texture coordinates.

D3DTTFF_PROJECTED

The texture coordinates are all divided by the last element before being passed to the rasterizer. For example, if this flag is specified with the D3DTTFF_COUNT3 flag, the first and second texture coordinates will be divided by the third coordinate before being passed to the rasterizer.

D3DTTFF_FORCE_DWORD

Forces this enumeration to compile to 32 bits in size. This value is not used.
