HRESULT GetVertices(DWORD *lpdwVertexCount, D3DVECTOR *lpPosition,
D3DVECTOR *lpNormal);
Retrieves the position and normal vector of each vertex in a Direct3DRMFace object.
·Returns D3DRM_OK if successful, or an error otherwise. For a list of possible return codes, see Direct3D Retained-Mode Return Values.
lpdwVertexCount
Address of a variable that is filled with the number of vertices. This parameter cannot be NULL.
lpPosition and lpNormal
Arrays of D3DVECTOR structures that will be filled with the positions and normal vectors of the vertices, respectively. If both of these parameters are NULL, the method will fill the lpdwVertexCount parameter with the number of vertices that will be retrieved.
