D3DXCreateMesh
Creates a mesh object using a declarator.
HRESULT D3DXCreateMesh(
DWORD NumFaces,
DWORD NumVertices,
DWORD Options,
CONST DWORD* pDeclaration,
LPDIRECT3DDEVICE8 pDevice,
LPD3DXMESH* ppMesh
);
Parameters
- NumFaces
- [in] Number of faces for the mesh. This parameter must be greater than 0.
- NumVertices
- [in] Number of vertices for the mesh. This parameter must be greater than 0.
- Options
- [in] A combination of one or more flags, specifying 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.
- pDeclaration
- [in] Pointer to a DWORD value, representing the declarator that describes the vertex format for the returned mesh. This parameter must map directly to an FVF.
- pDevice
- [in] Pointer to an IDirect3DDevice8 interface, the device object to be associated with the mesh.
- ppMesh
- [out] Address of a pointer to an ID3DXMesh interface, representing the created mesh object.
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.
