Data Structures
struct	nsearch::PointCloudAdaptor
	Allows custom point cloud data structure to interface with nanoflann. See https://github.com/jlblancoc/nanoflann for more details. More...
class	nsearch::TreeSearchResult< _DistanceType, _IndexType >
	To collect results of nanoflann tree search. Default result output of nanoflann search uses std::vector<std::pair<size_t, double>>. We prefer to get the index and distance in a separate list. More...
class	nsearch::TreeSearchCheckIDExcludeResult< _DistanceType, _IndexType >
	To collect results of nanoflann tree search. In this class, we check the tag of a potential point and add the point to search list if the tag does not match the tag of a point for which neighbors are computed. This is useful when computing neighbor list for contact. In this case, we do not want points from the same particle to be in the contact neighbor lsit. Default result output of nanoflann search uses std::vector<std::pair<size_t, double>>. We prefer to get the index and distance in a separate list. More...
class	nsearch::TreeSearchCheckIDIncludeResult< _DistanceType, _IndexType >
	To collect results of nanoflann tree search. In this class, we check the tag of a potential point and add the point to search list if the tag matches the tag of a point for which neighbors are computed. This is useful when computing neighbor list for peridynamics. In this case, we want points from the same particle to be in the peridynamics neighbor lsit. Default result output of nanoflann search uses std::vector<std::pair<size_t, double>>. We prefer to get the index and distance in a separate list. More...
