Retrieves vertex information for a specified group in a Direct3DRMMesh object.
HRESULT GetVertices(
D3DRMGROUPINDEX id,
DWORD index,
DWORD count,
D3DRMVERTEX *returnPtr
);
Parameters
id
Identifier of the group. This identifier must have been produced by using the IDirect3DRMMesh::AddGroup method.
index
Index into the array of D3DRMVERTEX structures at which to begin returning vertex positions.
count
Number of D3DRMVERTEX structures (vertices) to retrieve following the index given in the index parameter. This parameter cannot be NULL. To retrieve the number of vertices in a group, call the IDirect3DRMMesh::GetGroup method.
returnPtr
Array of D3DRMVERTEX structures that will contain the vertex information (vertex positions, colors, texture coordinates, and so on) when the method returns.
Return Values
Returns D3DRM_OK if successful, or an error otherwise. For a list of possible return codes, see Direct3D Retained-Mode Return Values.
