class FSceneViewStateInterface

Remarks

The scene manager's persistent view state.

Variables

		Name	Description
	uint8: 1	bValidEyeAdaptationBuffer
	uint8: 1	bValidEyeAdaptationTexture

Constructors

	Name	Description
	FSceneViewStateInterface()

Destructors

	Name	Description
	~FSceneViewStateInterface()	Don't allow direct deletion of the view state, Destroy should be called instead.

Functions

	Name	Description
void	ActivateFrozenViewMatrices ( FSceneView& SceneView )	If frozen view matrices are available, set those as active on the SceneView
void	AddReferencedObjects ( FReferenceCollector& Collector )
void	ClearMIDPool()	Clears the pool of mids being referenced by this view state
void	Destroy()	Called in the game thread to destroy the view state.
FSceneViewSt...	GetConcreteViewState()
const FExpos...	GetCurrentEyeAdaptationBuffer()	Returns the eye adaptation buffer (mobile only).
IPooledRende...	GetCurrentEyeAdaptationTexture()	Returns the eye adaptation texture (SM5+ only).
uint32	GetCurrentTemporalAASampleIndex()
uint32	GetCurrentUnclampedTemporalAASampleIndex()
const FViewM...	GetFrozenViewMatrices()	If frozen view matrices are available, return a pointer to them
uint32	GetOcclusionFrameCounter()	Returns the occlusion frame counter
float	GetPreExposure()	Returns the current PreExposure value.
UMaterialIns...	GetReusableMID ( UMaterialInterface* InSource )	Allows MIDs being created and released during view rendering without the overhead of creating and releasing objects As MID are not allowed to be parent of MID this gets fixed up by parenting it to the next Material or MIC
ESequencerSt...	GetSequencerState()
SIZE_T	GetSizeBytes()
FTemporalLOD...	GetTemporalLODState()	Returns the temporal LOD struct from the viewstate
const FTempo...	GetTemporalLODState()
float	GetTemporalLODTransition()	Returns the blend factor between the last two LOD samples
uint32	GetViewKey()	Returns a unique key for the view state, non-zero
FSceneViewSt...	GetViewParent()
const FScene...	GetViewParent()
bool	HasValidEyeAdaptationBuffer()
bool	HasValidEyeAdaptationTexture()	Tells if the eye adaptation texture / buffer exists without attempting to allocate it.
bool	HasViewParent()
bool	IsViewParent()
void	OnStartPostProcessing ( FSceneView& CurrentView )	Resets pool for GetReusableMID()
void	ResetViewState()	Rest some state (e.g. FrameIndexMod8, TemporalAASampleIndex) to make the rendering [more] deterministic
void	RestoreUnfrozenViewMatrices ( FSceneView& SceneView )	If frozen view matrices were set, restore the previous view matrices
void	SetSequencerState ( ESequencerState InSequencerState )
void	SetViewParent ( FSceneViewStateInterface* InVi... )	Sets the view state's scene parent.
