Detailed Description

template<typename Traits>
class Ponca::KnnGraphBase< Traits >

Customizable base class for KnnGraph datastructure.

Constructor & Destructor Documentation

◆ KnnGraphBase()

template<typename Traits >
template<typename KdTreeTraits >
Ponca::KnnGraphBase< Traits >::KnnGraphBase ( const KdTreeBase< KdTreeTraits > &  kdtree,
int  k = 6 
)
inline

Build a KnnGraph from a KdTreeDense.

Parameters
kNumber of requested neighbors. Might be reduced if k is larger than the kdtree size - 1 (query point is not included in query output, thus -1)
Warning
Stores a const reference to kdtree.point_data()
KdTreeTraits compatibility is checked with static assertion
