Detailed Description

Implements a thin data abstraction such that the UploadGeneral function can upload primitive data from both scene primitives and dynamic primitives (which are not stored in the same way).

FUploadDataSourceAdapterScenePrimitives::FUploadDataSourceAdapterScenePrimitives ( FScene &  InScene,
uint32  InSceneFrameNumber,
TArray< FPersistentPrimitiveIndex >  InPrimitivesToUpdate,
TArray< EPrimitiveDirtyState >  InPrimitiveDirtyState

Member Function Documentation

◆ GetInstanceInfo()

FORCEINLINE_GPUSCENE void FUploadDataSourceAdapterScenePrimitives::GetInstanceInfo ( int32  ItemIndex,
FInstanceUploadInfo &  InstanceUploadInfo 
) const
inline

◆ GetItemPrimitiveIds()

FORCEINLINE_GPUSCENE TArrayView< const uint32 > FUploadDataSourceAdapterScenePrimitives::GetItemPrimitiveIds ( ) const
inline

◆ GetLightMapInfo()

FORCEINLINE_GPUSCENE bool FUploadDataSourceAdapterScenePrimitives::GetLightMapInfo ( int32  ItemIndex,
FLightMapUploadInfo &  UploadInfo 
) const
inline

◆ GetPrimitiveInfoHeader()

FORCEINLINE_GPUSCENE void FUploadDataSourceAdapterScenePrimitives::GetPrimitiveInfoHeader ( int32  ItemIndex,
FPrimitiveUploadInfoHeader &  PrimitiveUploadInfo 
) const
inline

Populate the primitive info for a given item index.

◆ GetPrimitiveShaderData()

FORCEINLINE_GPUSCENE void FUploadDataSourceAdapterScenePrimitives::GetPrimitiveShaderData ( int32  ItemIndex,
FVector4f *RESTRICT  OutData 
) const
inline

Populate the primitive info for a given item index.

◆ NumPrimitivesToUpload()

FORCEINLINE_GPUSCENE int32 FUploadDataSourceAdapterScenePrimitives::NumPrimitivesToUpload ( ) const
inline

Return the number of primitives to upload N, GetPrimitiveInfoHeader/GetPrimitiveShaderData will be called with ItemIndex in [0,N).

◆ PackFlags()
