Data Structures

class  BaseNSearch
 A class for nearest neighbor search. More...
 
class  NFlannSearchKd
 A class for nearest neighbor search using nanoflann library. More...
 
struct  PointCloudAdaptor
 Allows custom point cloud data structure to interface with nanoflann. See https://github.com/jlblancoc/nanoflann for more details. More...
 
class  TreeSearchCheckIDExcludeResult
 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...
