class IFrameBuffer;

The IFrameBuffer interface represents a framebuffer, which receives the output from drawing operations. Framebuffers are used by attaching them to an IRenderPassNode A framebuffer doesn't hold storage by itself, it must be bound to something to write to. A framebuffer can be bound directly to a window surface, allowing the result of drawing operations to appear on the screen and be shown to the user. A framebuffer can also be bound to one or more texture targets. Within a pixel shader it is possible to write to multiple independent output targets, which can be bound on the framebuffer as separate textures. These textures can then be used as input resources for subsequent render passes or composite passes when performing multi-pass rendering.

Generally speaking, the final contents of a rendering operation are not directly accessible to the program. Modern graphics hardware is designed around producing images on the graphics card, and passing those images directly out to the display or using them in subsequent drawing operations. If it is required to read back the results of drawing operations, such as for producing screenshots, this can be done by attaching an IFrameBufferOutput object to the framebuffer, using the AddOutputCaptureTarget method. Please be aware that due to the inherent overhead in reading back resulting buffer contents from the hardware, this may have a significant impact on render times, so it is advisable to only leave a IFrameBufferOutput object attached for the shortest time required.

Initialization methods

	Name	Description
	Delete	Schedules the object for deletion. After calling this method, the object will be destroyed after the current frame completes drawing.

Binding methods

	Name	Description
	BindTexture	Binds the specified texture to the framebuffer
	UnbindTexture	Unbinds a preiously bound texture from the framebuffer
	BindMultiSamplingResolveTexture	Binds a texture to resolve a multisampled framebuffer attachment to
	UnbindMultiSamplingResolveTexture	Unbinds a preiously bound multisample resolve texture
	BindWindow	Binds the specified window to the framebuffer
	NotifyWindowResized	Notifies the framebuffer that the bound native window drawable size has changed.

Viewport methods

	Name	Description
	DefineViewportRegion	Defines the position and size of the viewport to draw into within the bound texture or window
	DefineScissorRegion	Establishes a scissor region to restrict the region of the framebuffer that is drawn to
	RemoveScissorRegion	Removes a previously defined scissor region

Output capture methods

	Name	Description
	AddOutputCaptureTarget	Adds the specified output capture target to this framebuffer. This allows the results of rendering to a framebuffer to be retrieved by the application.
	RemoveOutputCaptureTarget	Removes the specified output capture target from this framebuffer.
