ID3DXBaseMesh::CloneMesh

Clones a mesh using a declarator.

HRESULT CloneMesh(
  DWORD Options,
  CONST DWORD* pDeclaration,
  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.
pDeclaration
[in] Pointer to an array of DWORD values, representing the declarator to describe the vertex format of the vertices in the output mesh. This parameter must map directly to an FVF.
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.

D3DERR_INVALIDCALL
E_OUTOFMEMORY

Applies To

This method applies to the following interfaces, which inherit from ID3DXBaseMesh.

Requirements

  Header: Declared in D3dx8mesh.h.
  Import Library: Use D3dx8.lib.
