class UPCGLandscapeSplineData : public UPCGPolyLineData

	Type	Name	Description
	FInterpCurveFloat	ReparamTable	Reparameterization of the spline by distance. Useful to query the InputKey at arbitrary distance.
	TWeakObjectPtr< ULandscapeSplinesComponent >	Spline

Type	Name	Description
void	GetInterpPointAtDistance ( int SegmentIndex, FVector::FReal Distance, int32& OutPointIndex, bool bComputeAlpha, FVector::FReal& OutAlpha )	Get the index of the first interp point before a given distance.
void	Initialize ( ULandscapeSplinesComponent* InSplineComponent )
void	PostLoad ()
void	UpdateReparamTable ()	Recompute the reparameterization of the spline by distance.

Type	Name	Description
FVector::FReal	GetCurvatureAtDistance ( int SegmentIndex, FVector::FReal Distance )	Get the curvature at a distance along the line.
FVector::FReal	GetDistanceAtSegmentStart ( int SegmentIndex )	Get the cumulative distance along the line to the start of a segment.
float	GetInputKeyAtDistance ( int SegmentIndex, FVector::FReal Distance )	Get the input key at a distance along the line.
FVector	GetLocationAtAlpha ( float Alpha )	Get the location of the point at the normalized [0, 1] parameter across the entire the poly line.
int	GetNumSegments ()	Get the number of segments in this line.
FVector::FReal	GetSegmentLength ( int SegmentIndex )	Get the length of a specific segment of the line.
void	GetTangentsAtSegmentStart ( int SegmentIndex, FVector& OutArriveTangent, FVector& OutLeaveTangent )	Get the arrive and leave tangents for a control point via its segment index.
FTransform	GetTransform ()	Get the world-space transform of the entire line.
FTransform	GetTransformAtAlpha ( float Alpha )	Get the full transform at the normalized [0, 1] parameter across the entire the poly line.
FTransform	GetTransformAtDistance ( int SegmentIndex, FVector::FReal Distance, bool bWorldSpace, FBox* OutBounds )	Get the location at a distance along the line.
