Detailed Description

Tracks primitive transforms so they will be persistent across rendering state recreates.

Member Function Documentation

void FSceneVelocityData::ApplyOffset ( FVector Offset )

inline

bool FSceneVelocityData::GetComponentPreviousLocalToWorld	(	FPrimitiveComponentId	PrimitiveComponentId,
		FMatrix &	OutPreviousLocalToWorld
	)		const

inline

Looks up the PreviousLocalToWorld state for the given component. Returns false if none is found (the primitive has never been moved).

void FSceneVelocityData::OverridePreviousTransform	(	FPrimitiveComponentId	PrimitiveComponentId,
		const FMatrix &	PreviousLocalToWorld
	)

inline

Overrides a primitive's previous LocalToWorld matrix for this frame only

void FSceneVelocityData::RemoveFromScene	(	FPrimitiveComponentId	PrimitiveComponentId,
		bool	bImmediate
	)

inline

void FSceneVelocityData::StartFrame ( FScene * Scene )

Must be called once per frame, even when there are multiple EndDrawingViewports.

void FSceneVelocityData::UpdateTransform	(	FPrimitiveSceneInfo *	PrimitiveSceneInfo,
		const FMatrix &	LocalToWorld,
		const FMatrix &	PreviousLocalToWorld
	)

inline

Updates a primitives current LocalToWorld state.
