KDTree

Simple C++ static KD-Tree implementation with minimal functionality.

  • points are given as STL vectors (and inserted in their own STL vector) so supports n-dimensional points for any n
  • makes full trees, (i.e. does not cut-off the branching at some arbitrary level) giving the nearest neighbor query have (strong) logarithmic complexity.
  • builds the tree in one go (does not support adding nodes, the tree is built from a list of points and cannot be altered afterwards)
  • points are assumed to be STL vectors
  • it provides the following queries:
    • nearest neighbor
    • neighbors within a given distance
    • k nearest neighbours

News

Version 2.0.0

  • Added K nearest neighbours query.
