Detailed Description

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

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

T	Type of the elements (e.g. double, float, uint8_t)
DataSource	Source of the data, i.e. where the vectors are stored
_DistanceType	Type of distance variables (must be signed)
IndexType	Type of the arguments with which the data can be accessed (e.g. float, double, int64_t, T*)
