ID3DXRenderToSurface interface

The ID3DXRenderToSurface interface is used to generalize the process of rendering to surfaces.

Members

The ID3DXRenderToSurface interface inherits from the IUnknown interface. ID3DXRenderToSurface also has these types of members:

• Methods

Methods

The ID3DXRenderToSurface interface has these methods.

Method	Description
BeginScene	Begins a scene.
EndScene	Ends a scene.
GetDesc	Retrieves the parameters of the render surface.
GetDevice	Retrieves the Direct3D device associated with the render surface.
OnLostDevice	Use this method to release all references to video memory resources and delete all stateblocks. This method should be called whenever a device is lost or before resetting a device.
OnResetDevice	Use this method to re-acquire resources and save initial state.

 

Remarks

Surfaces can be used in a variety of ways including render targets, off-screen rendering, or rendering to textures.

A surface can be configured using a separate viewport using the ID3DXRenderToSurface::BeginScene method, to provide a custom render view. If the surface is not a render target, a compatible render target is used, and the result is copied to the surface at the end of the scene.

The ID3DXRenderToSurface interface is obtained by calling the D3DXCreateRenderToSurface function.

The LPD3DXRENDERTOSURFACE type is defined as a pointer to the ID3DXRenderToSurface interface.

typedef interface ID3DXRenderToSurface ID3DXRenderToSurface;
typedef interface ID3DXRenderToSurface *LPD3DXRENDERTOSURFACE;
