◆ CreateHitProxies() [1/2]

HHitProxy * FInstancedStaticMeshSceneProxy::CreateHitProxies	(	IPrimitiveComponent *	Component,
		TArray< TRefCountPtr< HHitProxy > > &	OutHitProxies
	)

overridevirtual

Creates the hit proxies are used when DrawDynamicElements is called. Called in the game thread.

Parameters

OutHitProxies - Hit proxies which are created should be added to this array.

Returns: The hit proxy to use by default for elements drawn by DrawDynamicElements.

Reimplemented from FPrimitiveSceneProxy.

◆ CreateHitProxies() [2/2]

HHitProxy * FInstancedStaticMeshSceneProxy::CreateHitProxies	(	UPrimitiveComponent *	Component,
		TArray< TRefCountPtr< HHitProxy > > &	OutHitProxies
	)

overridevirtual

All FPrimitiveSceneProxy derived classes can decide to fully override the HHitProxy creation, or add their own and call any of their base classes to add theirs.

Classes deriving from FPrimitiveSceneProxy which are meant to be used with IPrimitiveComponent should override both CreateHitProxies(UPrimitiveComponent*, ...) and CreateHitProxies(IPrimitiveComponent*, ...) and make the UPrimitiveComponent version call into the IPrimitiveComponent one. This allows their derived classes that are exclusive to UPrimitiveComponent to call into them and to reroute the proxy creation to the IPrimitiveComponent path. Creates the hit proxies are used when DrawDynamicElements is called. Called in the game thread.

Parameters

OutHitProxies - Hit proxes which are created should be added to this array.

Returns: The hit proxy to use by default for elements drawn by DrawDynamicElements.

Reimplemented from FPrimitiveSceneProxy.

◆ CreateRenderThreadResources()

void FInstancedStaticMeshSceneProxy::CreateRenderThreadResources ( FRHICommandListBase & RHICmdList )

overridevirtual

Called when the rendering thread adds the proxy to the scene. This function allows for generating renderer-side resources. Called in the rendering thread.

Reimplemented from FStaticMeshSceneProxy.

Reimplemented in FHierarchicalStaticMeshSceneProxy.

◆ DestroyRenderThreadResources()

void FInstancedStaticMeshSceneProxy::DestroyRenderThreadResources ( )

overridevirtual

Called when the rendering thread removes the proxy from the scene. This function allows for removing renderer-side resources. Called in the rendering thread.

Reimplemented from FStaticMeshSceneProxy.

◆ GetDistanceFieldAtlasData()

		float &	SelfShadowBias
	)		const

overridevirtual

Reimplemented from FStaticMeshSceneProxy.

◆ GetDynamicMeshElements()

void FInstancedStaticMeshSceneProxy::GetDynamicMeshElements	(	const TArray< const FSceneView * > &	Views,
		const FSceneViewFamily &	ViewFamily,
		uint32	VisibilityMap,
		FMeshElementCollector &	Collector
	)		const

overridevirtual

Gathers the primitive's dynamic mesh elements. This will only be called if GetViewRelevance declares dynamic relevance. This is called from the rendering thread for each set of views that might be rendered.
Game thread state like UObjects must have their properties mirrored on the proxy to avoid race conditions. The rendering thread must not dereference UObjects. The gathered mesh elements will be used multiple times, any memory referenced must last as long as the Collector (eg no stack memory should be referenced). This function should not modify the proxy but simply collect a description of things to render. Updates to the proxy need to be pushed from game thread or external events.

Parameters

Views	- the array of views to consider. These may not exist in the ViewFamily.
ViewFamily	- the view family, for convenience
VisibilityMap	- a bit representing this proxy's visibility in the Views array
Collector	- gathers the mesh elements to be rendered and provides mechanisms for temporary allocations

Reimplemented from FStaticMeshSceneProxy.

Reimplemented in FHierarchicalStaticMeshSceneProxy.

float FInstancedStaticMeshSceneProxy::GetGpuLodInstanceRadius ( ) const

overridevirtual

Returns the instance radius to use for per instance GPU LOD calculation. Returns 0.f if GPU LOD isn't enabled on the primitive.

Reimplemented from FPrimitiveSceneProxy.

◆ GetInstanceDataUpdateTaskInfo()

FInstanceDataUpdateTaskInfo * FInstancedStaticMeshSceneProxy::GetInstanceDataUpdateTaskInfo ( ) const

overridevirtual

Return a pointer to a class that can be used to guard access to instance data that is being updated by a task. The proxy must guarantee the lifetime of this object, and, since it is being used on the render thread be careful about how it is updated. In general, it must always be updated on the RT if it is visible to the RT.

Reimplemented from FPrimitiveSceneProxy.

◆ GetInstanceDrawDistanceMinMax()

bool FInstancedStaticMeshSceneProxy::GetInstanceDrawDistanceMinMax ( FVector2f & OutDistanceMinMax ) const

overridevirtual

Retrieves the instance draw distance range (mostly only used by objects whose instances are culled on the GPU)

Parameters

OutDistanceMinMax contains the min/max camera distance of the primitive's instances when enabled

Returns: bool true if camera distance culling is enabled for this primitive's instances

Reimplemented from FPrimitiveSceneProxy.

overridevirtual

Determines the relevance of this primitive's elements to the given light.

Parameters

overridevirtual

Return a type (or subtype) specific hash for sorting purposes

Implements FPrimitiveSceneProxy.

◆ GetViewRelevance()

virtual FPrimitiveViewRelevance FInstancedStaticMeshSceneProxy::GetViewRelevance ( const FSceneView * View ) const

inlineoverridevirtual

Parameters

View	- The view to determine relevance for.
