ID3DXContext

Applications use the methods of the ID3DXContext interface to encapsulate all of the various Direct3D and DirectDraw objects required to render a scene This section is a reference to the methods of this interface.

The ID3DXContext interface is obtained by calling the D3DXCreateContext function or the D3DXCreateContextEx function.

The methods of the ID3DXContext interface can be organized into the following groups:

Buffer Management GetBackBuffer
  GetBufferSize
GetNumBackBuffers
GetPrimary
GetZBuffer
Resize
Information GetDD
  GetD3D
GetD3DDevice

The ID3DXContext interface, like all COM interfaces, inherits the IUnknown interface methods. The IUnknown interface supports the following three methods:

IUnknown AddRef
  QueryInterface

The PD3DXCONTEXT type is defined as a pointer to an ID3DXContext interface:

typedef struct ID3DXContext *PD3DXCONTEXT;
