After you create a depth buffer, as described in Creating a Depth Buffer, you enable depth buffering by calling the IDirect3DMobileDevice::SetRenderStatemethod. Set the D3DMRS_ZENABLE render state ( see D3DMRENDERSTATETYPE)to enable depth-buffering. Use the D3DMZB_TRUEmember of the D3DMZBUFFERTYPEenumerated type (or TRUE) to enable z-buffering, D3DMZB_USEW to enable w-buffering, or D3DMZB_FALSE (or FALSE) to disable depth buffering.

Note:
To use w-buffering, your application must set a compliant projection matrix even if it does not use the Microsoft® Direct3D® Mobile transformation pipeline. For information about providing an appropriate projection matrix, Projection Transformations.
