Member Function Documentation
◆ nearestK()
|
pure virtual |
Get the k-nearest neighbors of a point.
All the nearest neighbor structures currently return the neighbors in sorted order, but this is not required.
Implemented in ompl::NearestNeighborsGNATNoThreadSafety< std::shared_ptr< ompl::geometric::aitstar::Vertex > >, ompl::NearestNeighborsGNAT< NNElement >, ompl::NearestNeighborsGNAT< _T >, ompl::NearestNeighborsGNATNoThreadSafety< _T >, ompl::NearestNeighborsFLANN< _T, _Dist >, ompl::NearestNeighborsFLANN< _T, FLANNDistance< _T > >, and ompl::NearestNeighborsLinear< _T >.
◆ nearestR()
|
pure virtual |
Get the nearest neighbors of a point, within a specified radius.
All the nearest neighbor structures currently return the neighbors in sorted order, but this is not required.
Implemented in ompl::NearestNeighborsGNATNoThreadSafety< std::shared_ptr< ompl::geometric::aitstar::Vertex > >, ompl::NearestNeighborsGNAT< NNElement >, ompl::NearestNeighborsGNAT< _T >, ompl::NearestNeighborsGNATNoThreadSafety< _T >, ompl::NearestNeighborsFLANN< _T, _Dist >, ompl::NearestNeighborsFLANN< _T, FLANNDistance< _T > >, and ompl::NearestNeighborsLinear< _T >.
