Flexible Vertex Format Flags

Direct3D Immediate Mode uses flag values to describe vertex formats used for DrawPrimitive-based rendering. The CONST_D3DFVFFLAGS enumeration defines the following flags to explicitly describe a vertex format, and provides helper macros that act as common combinations of such flags. For more information, see About Vertex Formats.

Flexible vertex format (FVF) flags

D3DFVF_DIFFUSE

Vertex format includes a diffuse color component.

D3DFVF_LVERTEX

Vertex format is equivalent to the D3DLVERTEX vertex type.

D3DFVF_NORMAL

Vertex format includes a vertex normal vector. This flag cannot be used with the D3DFVF_XYZRHW flag.

D3DFVF_SPECULAR

Vertex format includes a specular color component.

D3DFVF_TLVERTEX

Vertex format is equivalent to the D3DTLVERTEX vertex type.

D3DFVF_VERTEX

Vertex format is equivalent to the D3DVERTEX vertex type.

D3DFVF_XYZ

Vertex format includes the position of an untransformed vertex. This flag cannot be used with the D3DFVF_XYZRHW flag. If you use this flag, you must also specify a vertex normal, a vertex color component (D3DFVF_DIFFUSE or D3DFVF_SPECULAR), or include at least one set of texture coordinates (D3DFVF_TEX1 through D3DFVF_TEX8).

D3DFVF_XYZRHW

Vertex format includes the position of a transformed vertex. This flag cannot be used with the D3DFVF_XYZ or D3DFVF_NORMAL flags. If you use this flag, you must also specify a vertex color component (D3DFVF_DIFFUSE or D3DFVF_SPECULAR) or include at least one set of texture coordinates (D3DFVF_TEX1 through D3DFVF_TEX8).

D3DFVF_XYZB1 through D3DFVF_XYZB5

Vertex format contains position data, and a corresponding number of weighting (beta) values to be used for multimatrix vertex blending operations. Currently, Direct3D can blend with up to three weighting values (and four blending matrices).

Texture-related FVF flags

D3DFVF_TEX0 through D3DFVF_TEX8

Number of texture coordinate sets for this vertex. The actual values for these flags are not sequential.
