child object position matrix/worldMatrix

In three.js. I have an object(called container)(cube size 2.75,0.40,3.25). If I add 4 smaller objects(called corners)(cubes size 0.25,0.05,0.25) to the corners of the container, how can I get the scene positions of the smaller object(the corners), not the positions that I used to put them in the container.

I have figured out what I needed to know. - Mike O

Try something like this:

var Pos = new THREE.Vector3();
var Quat = new THREE.Quaternion(); 
var Scale = new THREE.Vector3();
object.matrixWorld.decompose(Pos, Quat , Scale);

Then you can get the needed info like this:

var neededInfo = Pos.x;//or Pos.y or Pos.z
