<h1>[name]</h1>
<p class="desc">
Helper object to visualize a [page:Box3].
</p>
<h2>Example</h2>
<code>
var box = new THREE.Box3();
box.setFromCenterAndSize( new THREE.Vector3( 1, 1, 1 ), new THREE.Vector3( 2, 1, 3 ) );
var helper = new THREE.Box3Helper( box, 0xffff00 );
scene.add( helper );
</code>
<h2>Constructor</h2>
<h3>[name]( [param:Box3 box], [param:Color color] )</h3>
<p>
[page:Box3 box] -- the Box3 to show.<br />
[page:Color color] -- (optional) the box's color. Default is 0xffff00.<br /><br />
Creates a new wireframe box that represents the passed Box3.
</p>
<h2>Properties</h2>
<p>See the base [page:LineSegments] class for common properties.</p>
<h3>[property:Box3 box]</h3>
<p>The Box3 being visualized.</p>
<h2>Methods</h2>
<p>See the base [page:LineSegments] class for common methods.</p>
<h3>[method:void updateMatrixWorld]( [param:Boolean force] )</h3>
<p>
This overrides the method in the base [page:Object3D] class so that it
also updates the wireframe box to the extent of the [page:Box3Helper.box .box]
property.
