Member Function Documentation

◆ accum_dist()

template<class T >
template<typename U , typename V >
ResultType rtflann::MinkowskiDistance< T >::accum_dist ( const U &  a,
const V &  b,
int   
) const
inline

Partial distance, used by the kd-tree.

Definition at line 307 of file dist.h.

◆ operator()()

template<class T >
template<typename Iterator1 , typename Iterator2 >
ResultType rtflann::MinkowskiDistance< T >::operator() ( Iterator1  a,
Iterator2  b,
size_t  size,
ResultType  worst_dist = -1 
) const
inline

Compute the Minkowsky (L_p) distance between two vectors.

This is highly optimised, with loop unrolling, as it is one of the most expensive inner loops.

The computation of squared root at the end is omitted for efficiency.
