);
Parameters
- pFilename
- [in] Pointer to a string that specifies the name of the DirectX file to load.
- Options
- [in] A combination of one or more flags, specifying creation options for the mesh. The following flags are defined.
- D3DXMESH_32BIT
- The mesh has 32-bit indices instead of 16-bit indices. A 32-bit mesh can support up to 2^32-1 faces and vertices. This flag is not supported and should not be used.
- D3DXMESH_DONOTCLIP
- Use the D3DUSAGE_DONOTCLIP usage flag for vertex and index buffers.
- D3DXMESH_DYNAMIC
- Equivalent to specifying both D3DXMESH_VB_DYNAMIC and D3DXMESH_IB_DYNAMIC.
- D3DXMESH_RTPATCHES
- Use the D3DUSAGE_RTPATCHES usage flag for vertex and index buffers.
- D3DXMESH_NPATCHES
- Specifying this flag causes the vertex and index buffer of the mesh to be created with D3DUSAGE_NPATCHES flag. This is required if the mesh object is to be rendered using N-Patch enhancement using Microsoft® Direct3D®.
- D3DXMESH_MANAGED
- Equivalent to specifying both D3DXMESH_VB_MANAGED and D3DXMESH_IB_MANAGED.
- D3DXMESH_POINTS
- Use the D3DUSAGE_POINTS usage flag for vertex and index buffers.
- D3DXMESH_IB_DYNAMIC
- Use the D3DUSAGE_DYNAMIC usage flag for index buffers.
- D3DXMESH_IB_MANAGED
- Use the D3DPOOL_MANAGED memory class for index buffers.
- D3DXMESH_IB_SYSTEMMEM
- Use the D3DPOOL_SYSTEMMEM memory class for index buffers.
- D3DXMESH_IB_WRITEONLY
- Use the D3DUSAGE_WRITEONLY usage flag for index buffers.
- D3DXMESH_SYSTEMMEM
- Equivalent to specifying both D3DXMESH_VB_SYSTEMMEM and D3DXMESH_IB_SYSTEMMEM.
- D3DXMESH_VB_DYNAMIC
- Use the D3DUSAGE_DYNAMIC usage flag for vertex buffers.
- D3DXMESH_VB_MANAGED
- Use the D3DPOOL_MANAGED memory class for vertex buffers.
- D3DXMESH_VB_SYSTEMMEM
- Use the D3DPOOL_SYSTEMMEM memory class for vertex buffers.
- D3DXMESH_VB_WRITEONLY
- Use the D3DUSAGE_WRITEONLY usage flag for vertex buffers.
- D3DXMESH_WRITEONLY
- Equivalent to specifying both D3DXMESH_VB_WRITEONLY and D3DXMESH_IB_WRITEONLY.
- pDevice
- [in] Pointer to an IDirect3DDevice8 interface, the device object associated with the mesh.
- ppAdjacency
- [out] Address of a pointer to an ID3DXBuffer interface. When the method returns, this parameter is filled with an array of three DWORDs per face that specify the three neighbors for each face in the mesh.
- ppMaterials
- [out] Address of a pointer to an ID3DXBuffer interface. When this method returns, this parameter is filled with an array of D3DXMATERIAL structures, containing information saved in the Microsoft® DirectX® file.
- pNumMaterials
- [out] Pointer to the number of D3DXMATERIAL structures in the ppMaterials array, when the method returns.
- ppMesh
- [out] Address of a pointer to an ID3DXMesh interface, representing the loaded mesh.
Return Values
If the function succeeds, the return value is D3D_OK.
If the function fails, the return value can be one of the following values.
Note All the meshes in the file will be collapsed into one output mesh. If the file contains a frame hierarchy, all the transformations will be applied to the mesh.
