ID3DXRenderToSurface Interface

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

ID3DXRenderToSurface Members

BeginScene	Begins a scene.
EndScene	Ends a scene.
GetDesc	Retrieves the parameters of the render surface.
GetDevice	Retrieves the Microsoft?Direct3D?device associated with the render surface.
OnLostDevice	Releases all references to video memory resources and deletes all stateblocks.
OnResetDevice	Should be called after the device has been reset.

Remarks

Surfaces can be used in a variety of ways including render targets, off-screen rendering, or rendering to textures. An example of off-screen rendering can be seen in the Water Sample.

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* LPD3DXRENDERTOSURFACE;
