nanoflann::L2_Simple_Adaptor< T, DataSource, _DistanceType > Struct Template Reference

Detailed Description

template<class T, class DataSource, typename _DistanceType = T>
struct nanoflann::L2_Simple_Adaptor< T, DataSource, _DistanceType >

Squared Euclidean (L2) distance functor (suitable for low-dimensionality datasets, like 2D or 3D point clouds) Corresponding distance traits: nanoflann::metric_L2_Simple.

Template Parameters
TType of the elements (e.g. double, float, uint8_t)
_DistanceTypeType of distance variables (must be signed) (e.g. float, double, int64_t)
