Quadtrees in Ruby. For searching spatially related nodes in some space, you know.
Add this line to your application's Gemfile:
And then execute:
Or install it yourself as:
$ gem install quadtree
Load it in your code to start building quadtrees:
require 'quadtree' boundary = ::.(::.(19.8470050, 60.3747940), 8944.0) qt = ::.(boundary)
Then you can do lookups and such:
getaboden = ::.(19.8470050, 60.3747940, "Getaboden") knutnas = ::.(19.8271170, 60.3505570, "Knutnäs") boundary = ::.(::.(19.8470050, 60.3747940), 8944.0) boundary2 = ::.(::.(19.8470050, 60.3747940), 4472.0) qt.insert! getaboden qt.insert! knutnas qt.query_range(boundary2) # [#<Quadtree::Point:0x00007fdcb19e0698 @data="Getaboden", @x=19.847005, @y=60.374794>, #<Quadtree::Point:0x00007fdcb19ec7b8 @data="Knutnäs", @x=19.827117, @y=60.350557>]
After checking out the repo, run
