bounding-box-overlap-test

test if two n-dimensional bounding boxes overlap

example

var overlap = require('bounding-box-overlap-test')
var a = [ [3,8], [-15,-11], [100,110] ]
var b = [ [1,5], [-12,-5], [80,140] ]
var c = [ [-4,6], [-10,0], [70,90] ]
console.log(overlap(a, b)) // true 
console.log(overlap(a, c)) // false 
console.log(overlap(b, c)) // true 

api

var overlap = require('bounding-box-overlap-test')

overlap(a, b, opts={})

Return whether the bounding box a intersects the bounding box b.

Bounding boxes are arrays of 2-element [min,max] array pairs, one for each coordinate.

  • opts.cmp(a, b) - provide your own custom comparison function or array of comparison functions

Comparison functions should return -1, 0, or 1 for less than, equal to, and greater than cases, respectively.

If opts.cmp is an array, each item in the array should be a comparison function for the respective dimension.

install

npm install bounding-box-overlap-test
