ID3DXBaseMesh::CloneMeshFVF
Clones a mesh using a flexible vertex format (FVF) code.
HRESULT CloneMeshFVF(
DWORD Options,
DWORD FVF,
LPDIRECT3DDEVICE8 pD3DDevice,
LPD3DXMESH* ppCloneMesh
);
Parameters
- 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_SHARE
- Forces the cloned meshes to share vertex buffers. These meshes will have separate index buffers into the shared vertex buffer.
- 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.
- FVF
- [in] Combination of flexible vertex format flags that specifies the vertex format for the vertices in the output mesh.
- pD3DDevice
- [in] Pointer to a IDirect3DDevice8 interface representing the device object associated with the mesh.
- ppCloneMesh
- [out, retval] Address of a pointer to an ID3DXMesh interface, representing the cloned mesh.
Return Values
If the method succeeds, the return value is D3D_OK.
If the method fails, the return value can be one of the following values.
Applies To
This method applies to the following interfaces, which inherit from ID3DXBaseMesh.
Remarks
CloneMeshFVF can be used to convert a mesh from one FVF to another.
