Detailed Description

template<typename PointT, class Tree = pcl::KdTreeFLANN<PointT>>
class pcl::search::KdTree< PointT, Tree >

search::KdTree is a wrapper class which inherits the pcl::KdTree class for performing search functions using KdTree structure.

KdTree is a generic type of 3D spatial locator using kD-tree structures. The class is making use of the FLANN (Fast Library for Approximate Nearest Neighbor) project by Marius Muja and David Lowe.
