Name	Remarks	Include Path
virtual FBox GetBounds()	Returns the full bounds (including density fall-off) of the data	Data/PCGProjectionData.h
virtual int GetDimension()	Returns the dimension of the data type, which has nothing to do with the dimension of its points	Data/PCGProjectionData.h
virtual FVector GetNormal()	Returns the expected data normal (for surfaces) or eventual projection axis (for volumes)	Data/PCGProjectionData.h
virtual FBox GetStrictBounds()	Returns the bounds in which the density is always 1	Data/PCGProjectionData.h
virtual bool HasNonTrivialTransform()	Returns true if the data has a non-trivial transform	Data/PCGProjectionData.h
virtual void InitializeTargetMetadata ( const FPCGInitializeFromDataParams& InParams, UPCGMetadata* MetadataToInitialize ) const	Initialize another metadata from this data.	Data/PCGProjectionData.h
virtual bool RequiresCollapseToSample()	True if this operation does not have an inverse and cannot be queried analytically/implicitly, and therefore must be collapsed to an explicit point representation.	Data/PCGProjectionData.h
virtual bool SamplePoint ( const FTransform& Transform, const FBox& Bounds, FPCGPoint& OutPoint, UPCGMetadata* OutMetadata ) const	Sample rotation, scale and other attributes from this data at the query position.	Data/PCGProjectionData.h

Name	Remarks	Include Path	Unreal Specifiers
virtual void AddToCrc ( FArchiveCrc32& Ar, bool bFullDataCrc ) const	Adds this data to Crc.	Data/PCGProjectionData.h
