D3DXLoadMeshFromXof function

Loads a mesh from an ID3DXFileData object.

Syntax


HRESULT D3DXLoadMeshFromXof(
  _In_    LPD3DXFILEDATA    pxofMesh,
  _Out_   DWORD             Options,
  _In_    LPDIRECT3DDEVICE9 pDevice,
  _Out_   LPD3DXBUFFER      *ppAdjacency,
  _Inout_ LPD3DXBUFFER      *ppMaterials,
  _Out_   LPD3DXBUFFER      *ppEffectInstances,
  _Inout_ DWORD             *pNumMaterials,
  _Out_   LPD3DXMESH        *ppMesh
);

Parameters

pxofMesh [in]

Type: LPD3DXFILEDATA

Pointer to an ID3DXFileData interface, representing the file data object to load.

Options [out]

Type: DWORD

Combination of one or more flags from the D3DXMESH enumeration, specifying creation options for the mesh.

pDevice [in]

Type: LPDIRECT3DDEVICE9

Pointer to an IDirect3DDevice9 interface, the device object associated with the mesh.

ppAdjacency [out]

Type: LPD3DXBUFFER*

Pointer to a buffer that contains adjacency data. The adjacency data contains an array of three DWORDs per face that specify the three neighbors for each face in the mesh. For more information about accessing the buffer, see ID3DXBuffer.

ppMaterials [in, out]

Type: LPD3DXBUFFER*

Address of a pointer to an ID3DXBuffer interface. When the method returns, this parameter is filled with an array of D3DXMATERIAL structures.

ppEffectInstances [out]

Type: LPD3DXBUFFER*

Pointer to a buffer containing an array of effect instances, one per attribute group in the returned mesh. An effect instance is a particular instance of state information used to initialize an effect. See D3DXEFFECTINSTANCE. For more information about accessing the buffer, see ID3DXBuffer.

pNumMaterials [in, out]

Type: DWORD*

Pointer to the number of D3DXMATERIAL structures in the ppMaterials array, when the method returns.

ppMesh [out]

Type: LPD3DXMESH*

Address of a pointer to an ID3DXMesh interface, representing the loaded mesh.

Return value

Type: HRESULT

If the function succeeds, the return value is D3D_OK. If the function fails, the return value can be one of the following: D3DERR_INVALIDCALL, D3DXERR_INVALIDDATA, E_OUTOFMEMORY.

Remarks

For mesh files that do not contain effect instance information, default effect instances will be generated from the material information in the .x file. A default effect instance will have default values that correspond to the members of the D3DMATERIAL9 structure.

The default texture name is also filled in, but is handled differently. The name will be Texture0@Name, which corresponds to an effect variable by the name of "Texture0" with an annotation called "Name." This will contain the string file name for the texture.
