Detailed Description

The scene manager's private implementation of persistent view state. This class is associated with a particular camera across multiple frames by the game thread. The game thread calls FRendererModule::AllocateViewState to create an instance of this private implementation.

FOcclusionFeedback FSceneViewState::OcclusionFeedback

◆ OcclusionFrameCounter

uint32 FSceneViewState::OcclusionFrameCounter

◆ OcclusionQueryPool

FRenderQueryPoolRHIRef FSceneViewState::OcclusionQueryPool

The view's occlusion query pool.

◆ OrthoVoxelGridUniformBuffer

◆ OutputFrameIndex

uint32 FSceneViewState::OutputFrameIndex

◆ PendingPrevFrameNumber

uint32 FSceneViewState::PendingPrevFrameNumber

◆ PersistentSkyAtmosphereData

FPersistentSkyAtmosphereData FSceneViewState::PersistentSkyAtmosphereData

◆ PhysicalMipLevel

uint32 FSceneViewState::PhysicalMipLevel

◆ PhysicalRHI

FRHITexture* FSceneViewState::PhysicalRHI = nullptr

◆ PlanarReflectionOcclusionHistories

TMap<int32, FIndividualOcclusionHistory> FSceneViewState::PlanarReflectionOcclusionHistories

◆ PreExposure

float FSceneViewState::PreExposure

The current frame PreExposure

◆ PrevFrameNumber

uint32 FSceneViewState::PrevFrameNumber

◆ PrevFrameViewInfo

FPreviousViewInfo FSceneViewState::PrevFrameViewInfo

Informations of to persist for the next frame's FViewInfo::PrevViewInfo.

Under normal use case (temporal histories are not frozen), this gets cleared after setting FViewInfo::PrevViewInfo after being copied to FViewInfo::PrevViewInfo. New temporal histories get directly written to it.

When temporal histories are frozen (pause command, or r.Test.FreezeTemporalHistories), this keeps it's values, and the currently rendering FViewInfo should not update it. Refer to FViewInfo::bStatePrevViewInfoIsReadOnly.

◆ PrevLightScatteringConservativeDepthTexture

TRefCountPtr<IPooledRenderTarget> FSceneViewState::PrevLightScatteringConservativeDepthTexture

◆ PrevLightScatteringViewGridUVToViewRectVolumeUV

FVector2f FSceneViewState::PrevLightScatteringViewGridUVToViewRectVolumeUV

◆ PrevViewMatrixForOcclusionQuery

FMatrix44f FSceneViewState::PrevViewMatrixForOcclusionQuery

◆ PrevViewOriginForOcclusionQuery

FVector FSceneViewState::PrevViewOriginForOcclusionQuery

◆ PrimitiveFadingStates

FPrimitiveFadingStateMap FSceneViewState::PrimitiveFadingStates

For this view, the set of primitives that are currently fading, either in or out.

◆ PrimitiveOcclusionQueryPool

FFrameBasedOcclusionQueryPool FSceneViewState::PrimitiveOcclusionQueryPool

◆ Scale

float FSceneViewState::Scale = 0.f

◆ Scene

FScene* FSceneViewState::Scene

The scene pointer may be NULL – it's filled in by certain API calls that require a FSceneViewState and FScene to know about each other, Whenever a ViewState and Scene get linked, this pointer is set, and a pointer to the ViewState is added to an array in the Scene. The linking is necessary in cases where incremental FScene updates need to be reflected in cached data stored in FSceneViewState.

◆ SequencerState

ESequencerState FSceneViewState::SequencerState

◆ ShaderPrintStateData

FShaderPrintStateData FSceneViewState::ShaderPrintStateData

◆ ShadowOcclusionQueryMaps

TArray<ShadowKeyOcclusionQueryMap, TInlineAllocator<FOcclusionQueryHelpers::MaxBufferedOcclusionFrames> > FSceneViewState::ShadowOcclusionQueryMaps

◆ ShareOriginUniqueID

uint32 FSceneViewState::ShareOriginUniqueID

Cube map captures share an origin, allowing them to share things like global distance fields and Lumen scene data. Otherwise, this will just be the same as UniqueID.

◆ SimpleLightIdToForwardLightIndex

TMap<FSimpleLightId, int32> FSceneViewState::SimpleLightIdToForwardLightIndex

◆ Spectral

TRefCountPtr<IPooledRenderTarget> FSceneViewState::Spectral

◆ StochasticLighting
