Module documentation for 0.2.4

This package includes static and dynamic versions of k-d trees, as well as "Map" variants that store data at each point in the k-d tree structure. Supports nearest neighbor, k nearest neighbors, points within a given radius, and points within a given range. To learn to use this package, start with the documentation for the Data.KdTree.Static module.

Changes

0.2.4

  • Now exporting KdMap.Static.TreeNode to facilitate advanced usage of the library.

0.2.3

  • For internal priority queue implementation, use the heap library instead of pqueue library in order to build on ghc 7.10.

0.2.2

  • Relax lower version bound on QuickCheck to 2.5.

0.2.1

  • Relax upper version constraint for MonadRandom (benchmarking code)
  • Add Data.Point2d as dependency of executables so tests and benchmarks can be built from the archive downloaded on Hackage.

0.2.0

  • Lots and lots of renaming all throughout to more closely match terminology used in containers.
  • Removed kdt library dependency on QuickCheck (if not building testing code).
  • Removed testing module Point2d from public API
  • All structures now have Show instance
  • Static variants now have functions for dynamically inserting new points into existing structure, with caveat that these functions do not maintain balanced tree structure.
