Public Member Functions
virtual bool	GetRenderTargetDescriptions (const ezView &view, const ezArrayPtr< ezGALTextureCreationDescription *const > inputs, ezArrayPtr< ezGALTextureCreationDescription > outputs) override
	For a given input pin configuration, provide the output configuration of this node. Outputs is already resized to the number of output pins.

virtual void	Execute (const ezRenderViewContext &renderViewContext, const ezArrayPtr< ezRenderPipelinePassConnection const > inputs, const ezArrayPtr< ezRenderPipelinePassConnection const > outputs) override
	Render into outputs. Both inputs and outputs are passed in with actual texture handles. Disconnected pins have a nullptr value in the passed in arrays. You can now create views and render target setups on the fly and fill the output targets with data.

void	SetName (const char *szName)
	Sets the name of the pass.

const char *	GetName () const
	returns the name of the pass.

bool	IsStereoAware () const
	True if the render pipeline pass can handle stereo cameras correctly.

virtual void	InitRenderPipelinePass (const ezArrayPtr< ezRenderPipelinePassConnection const > inputs, const ezArrayPtr< ezRenderPipelinePassConnection const > outputs)
	After GetRenderTargetDescriptions was called successfully for each pass, this function is called with the inputs and outputs for review. Disconnected pins have a nullptr value in the passed in arrays. This is the time to create additional resources that are not covered by the pins automatically, e.g. a picking texture or eye adaptation buffer.

virtual void	ExecuteInactive (const ezRenderViewContext &renderViewContext, const ezArrayPtr< ezRenderPipelinePassConnection const > inputs, const ezArrayPtr< ezRenderPipelinePassConnection const > outputs)

virtual void	ReadBackProperties (ezView *pView)
	Allows for the pass to write data back using ezView::SetRenderPassReadBackProperty. E.g. picking results etc.

Detailed Description

Render pass that applies depth-aware blur to preserve edges.

Uses a bilateral filter that considers both spatial distance and depth difference to avoid blurring across edges. Implemented as a two-pass separable filter, which is technically approximate but works well in practice (hence "separated" not "separable").
