Simple C++ KD-Tree implementation

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
