<h2>Code Example</h2>
|
|
|
|
<code>
|
|
const box = new THREE.Box3();
|
|
box.setFromCenterAndSize( new THREE.Vector3( 1, 1, 1 ), new THREE.Vector3( 2, 1, 3 ) );
|
|
|
|
const 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 />
