				<div class="class-description"><p>Helper object to graphically show the world-axis-aligned bounding box
around an object. The actual bounding box is handled with <a href="Box3.html">Box3</a>,
this is just a visual helper for debugging. It can be automatically
resized with <a href="BoxHelper.html#update">BoxHelper#update</a> when the object it's created from
is transformed. Note that the object must have a geometry for this to work,
so it won't work with sprites.</p></div>

const object = new THREE.Mesh( sphere, new THREE.MeshBasicMaterial( 0xff0000 ) );
const box = new THREE.BoxHelper( object, 0xffff00 );
