octree
======
This is a simple Octree implementation in Haskell.

[![Build Status](https://api.travis-ci.org/mgajda/octree.png?branch=master)](https://api.travis-ci.org/mgajda/octree.png)

To use simply:

~~~ {.haskell}
module Main where

import Data.Octree as O

import Data.Vector.V3

main = do let oct = fromList [(Vector3 1 2 3, "a"),
                              (Vector3 3 4 5, "b"),
                              (Vector3 8 8 8, "c")]
              report msg elt = putStrLn $ msg ++ show elt
          report "Nearest     :" $ O.nearest     oct     $ Vector3 2 2 3
          report "Within range:" $ O.withinRange oct 5.0 $ Vector3 2 2 3
          return ()
~~~

*For now it uses AC-Vector package for vectors, but I may change it to use Tensor package used by OpenGL package, if there is interest.*
*So far I still wait for package with vector operations (like dot, cross producton, vector projection and rejection) on Tensor types.*
