3d axis aligned bounding boxes

aabb-3d

Axis aligned bounding boxes for fun and profit.

var aabb = require('aabb-3d')
 
var bounding_box = aabb([0, 0, 0], [12, 12, 12])   // x, y, z == 0; width, height, depth == 12 
  , other = aabb([10, 10, 10], [2, 2, 2])
 
bounding_box.intersects(other) // true 
bounding_box.translate([2, 2, 2])  // moves the bounding box 
bounding_box.expand(other)  // returns a new aabb that surrounds both bboxes 
 

API

returns a new aabb.

returns:

          width

moves the box. returns itself.

returns true if the two bounding boxes intersect (or touch at all.)

returns a new aabb representing the shared area of the two aabb's. returns null if the boxes don't intersect.
