Computing Bounding Sphere after static .OBJ loading with Three.js

I got the following code for loading a simple, non-animated .OBJ with a .MTL into Three.js. It's very simple indeed and works well, but when I add the line with computeBoundingSphere(), it fails with a "TypeError: object.computeBoundingSphere is not a function" :

var callbackIrali1 = function ( event ) {

    var object = event.content;
    object.computeBoundingSphere();
    scene.add( object );

};
var loaderIrali1 = new THREE.OBJMTLLoader();
loaderIrali1.addEventListener( 'load', callbackIrali1);
loaderIrali1.load( 'models/obj/irali/irali.obj', 'models/obj/irali/irali.mtl' );

The issue is, I can't find what type of object might be this event.content returned by the callback, and so I can't find how to apply the computeBoundingSphere() function to it.

Finally found it out by myself :
- The object returned by the Loader is an Object3D,
- Thus, it has 2 children : mesh and materials,
- So you have to find the first child, then extract its geometry, and then compute the bounding sphere.

Which gives the following line :

object.children[0].geometry.computeBoundingSphere();
