Constants
- D3DXMESH_32BIT
The mesh has 32-bit indices instead of 16-bit indices. See Remarks.
- D3DXMESH_DONOTCLIP
Use the D3DUSAGE_DONOTCLIP usage flag for vertex and index buffers.
- D3DXMESH_POINTS
Use the D3DUSAGE_POINTS usage flag for vertex and index buffers.
- 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_VB_SYSTEMMEM
Use the D3DPOOL_SYSTEMMEM memory class for vertex buffers.
- D3DXMESH_VB_MANAGED
Use the D3DPOOL_MANAGED memory class for vertex buffers.
- D3DXMESH_VB_WRITEONLY
Use the D3DPOOL_MANAGED memory class for vertex buffers.
- D3DXMESH_VB_DYNAMIC
Use the D3DUSAGE_DYNAMIC usage flag for vertex buffers.
- D3DXMESH_VB_SOFTWAREPROCESSING
Use the D3DUSAGE_SOFTWAREPROCESSING for flag for vertex buffers.
- D3DXMESH_IB_SYSTEMMEM
Use the D3DPOOL_SYSTEMMEM memory class for index buffers.
- D3DXMESH_IB_MANAGED
Use the D3DPOOL_MANAGED memory class for index buffers.
- D3DXMESH_IB_WRITEONLY
Use the D3DUSAGE_WRITEONLY usage flag for index buffers.
- D3DXMESH_IB_DYNAMIC
Use the D3DUSAGE_DYNAMIC usage flag for index buffers.
- D3DXMESH_IB_SOFTWAREPROCESSING
Use the D3DUSAGE_SOFTWAREPROCESSING usage flag for index buffers.
- D3DXMESH_VB_SHARE
Forces the cloned meshes to share vertex buffers.
- D3DXMESH_USEHWONLY
Use hardware processing only. For mixed-mode device, this flag will cause the system to use hardware (if supported in hardware) or will default to software processing.
- D3DXMESH_SYSTEMMEM
Equivalent to specifying both D3DXMESH_VB_SYSTEMMEM and D3DXMESH_IB_SYSTEMMEM.
- D3DXMESH_MANAGED
Equivalent to specifying both D3DXMESH_VB_MANAGED and D3DXMESH_IB_MANAGED.
- D3DXMESH_WRITEONLY
Equivalent to specifying both D3DXMESH_VB_WRITEONLY and D3DXMESH_IB_WRITEONLY.
- D3DXMESH_DYNAMIC
Equivalent to specifying both D3DXMESH_VB_DYNAMIC and D3DXMESH_IB_DYNAMIC.
- D3DXMESH_SOFTWAREPROCESSING
Equivalent to specifying both D3DXMESH_VB_SOFTWAREPROCESSING and D3DXMESH_IB_SOFTWAREPROCESSING.
Remarks
A 32-bit mesh (D3DXMESH_32BIT) can theoretically support (2^32)-1 faces and vertices. However, allocating memory for a mesh that large on a 32-bit operating system is not practical.
