Detailed Description

Custom Slate drawer to update slate post buffer

Member Function Documentation

◆ Draw_RenderThread()

void FPostBufferUpdater::Draw_RenderThread	(	FRDGBuilder &	GraphBuilder,
		const FDrawPassInputs &	Inputs
	)

overridevirtual

Called from the render thread during element drawing.

Reimplemented from ICustomSlateElement.

◆ PostCustomElementAdded()

void FPostBufferUpdater::PostCustomElementAdded ( class FSlateElementBatcher & ElementBatcher ) const

overridevirtual

Called from the game thread during element batching.

Reimplemented from ICustomSlateElement.

Member Data Documentation

◆ bBuffersToUpdateInitialized

bool FPostBufferUpdater::bBuffersToUpdateInitialized = false

True if buffers to update has been initialized. Used to ensure 'BuffersToUpdate_Renderthread' is only set once at initialization.

◆ BuffersToUpdate_Renderthread

ESlatePostRT FPostBufferUpdater::BuffersToUpdate_Renderthread = ESlatePostRT::None

Buffers that we should update, all of these buffers will be affected by 'bPerformDefaultPostBufferUpdate' if disabled This value is read by the Renderthread, so all non-initialization updates must be done via a render command. See 'FSlatePostBufferBlurProxy::OnUpdateValuesRenderThread' as an example.

Additionally, note that this value should be masked against the currently enabled buffers in 'USlateRHIRendererSettings'

◆ bUsePaintGeometry_Renderthread

bool FPostBufferUpdater::bUsePaintGeometry_Renderthread = false

True if we should use the subregion rect

◆ PaintGeometry_Renderthread

FPaintGeometry FPostBufferUpdater::PaintGeometry_Renderthread = FPaintGeometry()

Paint geometry to use for subregion processing

◆ ProcessorUpdaters

TMap<ESlatePostRT, TSharedPtr<FSlatePostProcessorUpdaterProxy> > FPostBufferUpdater::ProcessorUpdaters

Proxies used to update a post processor within a frame
