AddBufferLockReadbackPass()

template<typename ReadbackProcessingLambdaType >

void AddBufferLockReadbackPass	(	FRDGBuilder &	GraphBuilder,
		TRefCountPtr< FRDGPooledBuffer >	SourceBuffer,
		uint32	NumBytes,
		ReadbackProcessingLambdaType &&	ReadbackProcessingLambda
	)

AddClearIndirectDispatchArgs1DPass()

void AddClearIndirectDispatchArgs1DPass ( FRDGBuilder &  GraphBuilder, ERHIFeatureLevel::Type  FeatureLevel, FRDGBufferRef  IndirectArgsRDG, uint32  NumIndirectArgs, uint32  IndirectArgStride  )

inline

Clear indirect for 1D kernel launch, sets YZ grid dimensions to 1.

AddClearIndirectDispatchArgsPass()

void AddClearIndirectDispatchArgsPass	(	FRDGBuilder &	GraphBuilder,
		ERHIFeatureLevel::Type	FeatureLevel,
		FRDGBufferRef	IndirectArgsRDG,
		const FIntVector3 &	DimClearValue,
		uint32	NumIndirectArgs,
		uint32	IndirectArgStride
	)

Clear indirect args for GPU-side building, initializes the XYZ dimensions of the dispatch arg to DimClearValue and everything else in the strided range to zero. Can clear one or more args (NumIndirectArgs). IndirectArgStride gives the size (in uints) of each argument, this may be larger than the required size. E.g., to make space for an atomic counter.

CreateAndClearIndirectDispatchArgs()

FRDGBufferRef CreateAndClearIndirectDispatchArgs	(	FRDGBuilder &	GraphBuilder,
		ERHIFeatureLevel::Type	FeatureLevel,
		const TCHAR *	Name,
		const FIntVector3 &	DimClearValue,
		uint32	NumIndirectArgs,
		uint32	IndirectArgStride
	)

Create an indirect args buffer and clear it using AddClearIndirectDispatchArgsPass.

CreateAndClearIndirectDispatchArgs1D()

FRDGBufferRef CreateAndClearIndirectDispatchArgs1D ( FRDGBuilder &  GraphBuilder, ERHIFeatureLevel::Type  FeatureLevel, const TCHAR *  Name  )

inline

Create and initialize a singular indirect args buffer with size derived from FRHIDispatchIndirectParameters.

(

)

One Tile Quad Index Buffer

GetOneTileQuadVertexBuffer()

RENDERER_API FBufferRHIRef & GetOneTileQuadVertexBuffer

(

)

ShouldSkipNaniteLPIs()

bool ShouldSkipNaniteLPIs

(

EShaderPlatform

ShaderPlatform

)

Returns true if Nanite primitives are to be skipped in Light Primitive Interactions (LPI) and the primitive acceleration structure (octree).
