class FSceneViewStateInterface

Remarks

The scene manager's persistent view state.

Variables

  Type Name Description
Protected variable uint8: 1 bValidEyeAdaptationBuffer  

Constructors

  Type Name Description
Public function    

Destructors

  Type Name Description
Protected function Virtual   Don't allow direct deletion of the view state, Destroy should be called instead.

Functions

  Type Name Description
Public function void If frozen view matrices are available, set those as active on the SceneView
Public function Virtual void

AddLumenSceneData ( FSceneInterface* InScene,
float SurfaceCacheResolution
)

 Similar to above, but adds Lumen Scene Data
Public function void  
Public function Virtual void Adds a per-view virtual shadow map cache, which can help performance, at a cost in memory.
Public function void

ClearMIDPool ( FStringView MidParentRootPath
)

 Clears the pool of mids being referenced by this view state
Public function void

Destroy ()

 Called in the game thread to destroy the view state.
Public function FSceneViewState *  
Public function Const FRDGPooledBuffer * Returns the eye adaptation buffer.
Public function Const uint32  
Public function Const uint32 Returns the distance field temporal sample index
Public function Const const FViewMatrices * If frozen view matrices are available, return a pointer to them
Public function Const float Returns the eye adaptation exposure.
Public function Const uint32 Returns the occlusion frame counter
Public function Const float Returns the current PreExposure value.
Public function UMaterialInstanceDynamic * 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
Public function ESequencerState  
Public function Virtual Const SIZE_T  
Public function Const const FTemporalLODState &  
Public function FTemporalLODState & Returns the temporal LOD struct from the viewstate
Public function Const float Returns the blend factor between the last two LOD samples
Public function Const uint32 Returns a unique key for the view state, non-zero
Public function FRDGTextureRef Return the active volumetric cloud texture, can be null.
Public function Const bool  
Public function Const bool Tells if the eye adaptation buffer exists without attempting to allocate it.
Public function Const bool  
Public function void Resets pool for GetReusableMID()
Public function Virtual void  
Public function Virtual void  
Public function void Rest some state (e.g. FrameIndexMod8, TemporalAASampleIndex) to make the rendering [more] deterministic
Public function void If frozen view matrices were set, restore the previous view matrices
Public function void

SetSequencerState ( ESequencerState InSequencerState
)
