Detailed Description

Information about a visible light which isn't view-specific.

Member Function Documentation

ContainsOnlyVirtualShadowMaps()

bool FVisibleLightInfo::ContainsOnlyVirtualShadowMaps

(

)

const

Returns true if the light has only virtual shadow maps (or no shadows at all), i.e. no conventional shadow maps that are allocated

FindVirtualShadowMapShadowClipmapForView()

TSharedPtr< FVirtualShadowMapClipmap > FVisibleLightInfo::FindVirtualShadowMapShadowClipmapForView

(

const FViewInfo *

View

)

const

GetVirtualShadowMapId()

int32 FVisibleLightInfo::GetVirtualShadowMapId

(

const FViewInfo *

View

)

const

Prefer this to direct access of the VirtualShadowMapId member when a view is known. For directional lights this will attempt to find a clipmap associated with the given view, while the VirtualShadowMapId variable will simply be an arbitrary one of them if multiple exist.

Member Data Documentation

AllProjectedShadows

TArray<FProjectedShadowInfo*,SceneRenderingAllocator> FVisibleLightInfo::AllProjectedShadows

All visible projected shadows, output of shadow setup. Not all of these will be rendered.

CapsuleShadowsToProject

TArray<FProjectedShadowInfo*,SceneRenderingAllocator> FVisibleLightInfo::CapsuleShadowsToProject

OccludedPerObjectShadows

TArray<FProjectedShadowInfo*,SceneRenderingAllocator> FVisibleLightInfo::OccludedPerObjectShadows

A list of per-object shadows that were occluded. We need to track these so we can issue occlusion queries for them.

ProjectedPreShadows

TArray<TRefCountPtr<FProjectedShadowInfo>,SceneRenderingAllocator> FVisibleLightInfo::ProjectedPreShadows

All visible projected preshdows. These are not allocated on the mem stack so they are refcounted.

ShadowsToProject

TArray<FProjectedShadowInfo*,SceneRenderingAllocator> FVisibleLightInfo::ShadowsToProject

Shadows to project for each feature that needs special handling.

VirtualShadowMapClipmaps

TArray<TSharedPtr<FVirtualShadowMapClipmap>, SceneRenderingAllocator> FVisibleLightInfo::VirtualShadowMapClipmaps
