<h1>[name]</h1>

|

<div class="desc">Renders [page:ArrowHelper arrows] to visualize an object's [page:Face3 face] normals. Requires that the object's geometry be an instance of [page:Geometry] (does not work with [page:BufferGeometry]), and that face normals have been specified on all [page:Face3 faces] or calculated with [page:Geometry.computeFaceNormals computeFaceNormals].</div>

<h2>Example</h2>
|
|
|
|
<code>
|
|
geometry = new THREE.BoxGeometry( 10, 10, 10, 2, 2, 2 );
|
|
material = new THREE.MeshBasicMaterial( { color: 0xff0000 } );
|
|
object = new THREE.Mesh( geometry, material );
|
|
|
|
edges = new THREE.FaceNormalsHelper( object, 2, 0x00ff00, 1 );
|
|
|
|
scene.add( object );
|
|
scene.add( edges );
