VertexDeclaration for RHW

akira32

How do I define the VertexDeclaration for the RHW?

typedef struct {
        FLOAT x, y, z;     // 2-D coordinates
        FLOAT rhw;         // rhw
        FLOAT u, v;        // Texture coordinates
} sVertex_2D;
#define VERTEXFVF_2D (D3DFVF_XYZRHW | D3DFVF_TEX1)

D3DVERTEXELEMENT9 decl_2D[] =
{
        // offsets in bytes
        {0,  0, D3DDECLTYPE_FLOAT3, D3DDECLMETHOD_DEFAULT, D3DDECLUSAGE_POSITION, 0},
        {0, 12, D3DDECLTYPE_FLOAT1, D3DDECLMETHOD_DEFAULT, ??,   0},
        {0, 16, D3DDECLTYPE_FLOAT2, D3DDECLMETHOD_DEFAULT, D3DDECLUSAGE_TEXCOORD,   0},
        D3DDECL_END()
        };

I had solved it.
D3DVERTEXELEMENT9 decl_2D[] =
{
        // offsets in bytes
        {0,  0, D3DDECLTYPE_FLOAT4, D3DDECLMETHOD_DEFAULT, D3DDECLUSAGE_POSITIONT, 0},
        {0, 16, D3DDECLTYPE_FLOAT2, D3DDECLMETHOD_DEFAULT, D3DDECLUSAGE_TEXCOORD, 0},
        D3DDECL_END()
};
