Overridden from UPCGSpatialData

  Type Name Description
Protected function Virtual Const UPCGSpatialData *  
Public function Virtual Const FBox Returns the full bounds (including density fall-off) of the data
Public function Virtual Const int Returns the dimension of the data type, which has nothing to do with the dimension of its points
Public function Virtual void

GetResourceSizeEx ( FResourceSizeEx& CumulativeResourceSize
)

  
Public function Virtual Const bool

ProjectPoint ( const FTransform& InTransform,
const FBox& InBounds,
const FPCGProjectionParams& InParams,
FPCGPoint& OutPoint,
UPCGMetadata* OutMetadata
)

 Project the query point onto this data, and sample point and metadata information at the projected position.
Public function Virtual Const bool

SamplePoint ( const FTransform& Transform,
const FBox& Bounds,
FPCGPoint& OutPoint,
UPCGMetadata* OutMetadata
)

 Sample rotation, scale and other attributes from this data at the query position.
