SpletKDTreeSearcher model objects store the results of a nearest neighbor search that uses the K d-tree algorithm. Results include the training data, distance metric and its parameters, and maximum number of data points in each leaf node (that is, the bucket size). Spletnanoflann is a C++11 header-only library for building KD-Trees of datasets with different topologies: R 2, R 3 (point clouds), SO (2) and SO (3) (2D and 3D rotation groups). No support for approximate NN is provided. nanoflann does not require compiling or installing. You just need to #include in your code.
