Detailed Description

template<typename RealType>
struct UE::Geometry::TWrapAroundGridIndexer3< RealType >

Converts real-valued coordinates to integer grid coordinates, wrapping around outside the representable integer range.

Lacks a conversion back from the integer vector since it maps to multiple ranges, but this is frequently not needed. Also requires use of a function to iterate over a range, to ensure proper overflow.

Member Function Documentation

IterateAcrossBounds()

template<typename RealType >

void UE::Geometry::TWrapAroundGridIndexer3< RealType >::IterateAcrossBounds ( const TVector< RealType > &  RealMin, const TVector< RealType > &  RealMax, TFunctionRef< bool(const FVector3i &Index)>  ShouldContinue  ) const

inline

Iterate across a range of indices going from the one that corresponds to RealMean to one that corresponds to RealMax. Iteration stops early if the passed function returns false.

ToGrid()

template<typename RealType >

FVector3i UE::Geometry::TWrapAroundGridIndexer3< RealType >::ToGrid ( const TVector< RealType > &  P ) const

inline

Convert real-valued point to integer grid coordinates, wrapping around when P/CellSize falls outside the representable integer range.
