//Draw2D

// The 2-D vertex format and descriptor
typedef struct {
  FLOAT x, y, z;     // 2-D coordinates
  FLOAT rhw;         // rhw
  FLOAT u, v;        // Texture coordinates
} sVertex;
#define VERTEXFVF (D3DFVF_XYZRHW | D3DFVF_TEX1)


//Draw3D

// The 3-D vertex format and descriptor
typedef struct {
  FLOAT x, y, z;     // 3-D coordinates
  FLOAT u, v;        // Texture coordinates
} sVertex;
#define VERTEXFVF (D3DFVF_XYZ | D3DFVF_TEX1)

一般做2D的这样定义的比较多：
#define VERTEXFVF (D3DFVF_XYZ|D3DFVF_DIFFUSE|D3DFVF_TEX1)
struct CUSTOMVERTEX
{
float x, y, z;
DWORD color;
float tu, tv;       
};
