Detailed Description

A texture/mesh instance manager to manage dynamic components. The async view generated is duplicated so that the state can change freely.

Member Function Documentation

Add()

EAddComponentResult FDynamicRenderAssetInstanceManager::Add ( const UPrimitiveComponent *  Component, FStreamingTextureLevelContext &  LevelContext, float  MaxAllowedUIDensity = 0  )

finaloverridevirtual

Add a component streaming data, the LevelContext gives support for precompiled data.

Implements IRenderAssetInstanceManager.

CanManage()

bool FDynamicRenderAssetInstanceManager::CanManage ( const UPrimitiveComponent *  Component ) const

finaloverridevirtual

Return whether this component is be managed by this manager.

Implements IRenderAssetInstanceManager.

GetAllocatedSize()

uint32 FDynamicRenderAssetInstanceManager::GetAllocatedSize ( ) const

finaloverridevirtual

Return the size taken for sub-allocation.

Implements IRenderAssetInstanceManager.

GetAsyncView()

const FRenderAssetInstanceView * FDynamicRenderAssetInstanceManager::GetAsyncView ( bool  bCreateIfNull )

finaloverridevirtual

Return a view of the data that has to be 100% thread safe. The content is allowed to be updated, but not memory must be reallocated.

Implements IRenderAssetInstanceManager.

GetGameThreadView()

const FRenderAssetInstanceView * FDynamicRenderAssetInstanceManager::GetGameThreadView

(

)

GetReferencedComponents()

void FDynamicRenderAssetInstanceManager::GetReferencedComponents

(

TArray< const UPrimitiveComponent * > &

Components

)

IncrementalUpdate()

void FDynamicRenderAssetInstanceManager::IncrementalUpdate	(	FRemovedRenderAssetArray &	RemovedRenderAssets,
		float	Percentage
	)

IsReferenced()

bool FDynamicRenderAssetInstanceManager::IsReferenced ( const UPrimitiveComponent *  Component ) const

finalvirtual

Return whether this component can be managed by this manager.

Implements IRenderAssetInstanceManager.

OnCreateViewDone()

void FDynamicRenderAssetInstanceManager::OnCreateViewDone ( FRenderAssetInstanceView *  InView )

protected

OnPreGarbageCollect()

void FDynamicRenderAssetInstanceManager::OnPreGarbageCollect

(

FRemovedRenderAssetArray &

RemovedRenderAssets

)

Remove all pending components that are marked for delete. This prevents searching in the pending list for each entry.

OnRefreshVisibilityDone()

void FDynamicRenderAssetInstanceManager::OnRefreshVisibilityDone ( int32  BeginIndex, int32  EndIndex, const TArray< int32 > &  SkippedIndices, int32  FirstFreeBound, int32  LastUsedBound  )

protected

PrepareAsyncView()

void FDynamicRenderAssetInstanceManager::PrepareAsyncView ( )

finaloverridevirtual

Notify the manager that an async view will be requested on the next frame.

Implements IRenderAssetInstanceManager.

Refresh()

void FDynamicRenderAssetInstanceManager::Refresh ( float  Percentage )

finaloverrideprotectedvirtual

Refresh component data (bounds, last render time, min and max view distance) - see TextureInstanceView.

Implements IRenderAssetInstanceManager.

RegisterTasks()

void FDynamicRenderAssetInstanceManager::RegisterTasks

(

RenderAssetInstanceTask::FDoWorkTask &

AsyncTask

)

Remove()

void FDynamicRenderAssetInstanceManager::Remove ( const UPrimitiveComponent *  Component, FRemovedRenderAssetArray *  RemovedRenderAssets  )

finaloverridevirtual

Remove a component, the RemovedRenderAssets is the list of textures or meshes not referred anymore.

Implements IRenderAssetInstanceManager.
