public index_t closest_neighbor(const Point<dimension> & point)public index_t closest_neighbor(const Point<dimension> & point)Get the closest neighbor from the given point
point [in] The requested point
return the index of the closest point
radius_neighbors
public vector radius_neighbors(const Point<dimension> & point, double threshold_distance)public vector radius_neighbors(const Point<dimension> & point, double threshold_distance)Get the neighbors closer than a given distance from the given point or within a sphere
point [in] The center of the sphere
threshold_distance [in] The radius of the sphere
return the list of points inside this distance
neighbors
public vector neighbors(const Point<dimension> & point, index_t nb_neighbors)public vector neighbors(const Point<dimension> & point, index_t nb_neighbors)Get a number ol close neighbors from the given point
point [in] The requested point
nb_neighbors [in] The number of neighbors to return
return the list of points, it can be smaller than the requested number of neighbors if there is less neighbors than points in the tree
colocated_index_mapping
public ColocatedInfo colocated_index_mapping(double epsilon)public ColocatedInfo colocated_index_mapping(double epsilon)Compute a colocation mapping from the list of points
epsilon [in] The approximation allowed to test if two points are identical
return The information related to this colocated operation
