<h2>Example</h2>
|
||
|
|
|
||
|
|
<code>var dir = new THREE.Vector3( 1, 0, 0 );
|
||
|
|
var origin = new THREE.Vector3( 0, 0, 0 );
|
||
|
|
var length = 1;
|
||
|
|
var hex = 0xffff00;
|
||
|
|
|
||
|
|
var arrowHelper = new THREE.ArrowHelper( dir, origin, length, hex );
|
||
|
|
scene.add( arrowHelper );
|
||
|
|
</code>

<h2>Constructor</h2>
|
||
|
|
|
||
|
|
|
||
|
|
<h3>[name]([page:Vector3 dir], [page:Vector3 origin], [page:Number length], [page:Number hex], [page:Number headLength], [page:Number headWidth] )</h3>
|
||
|
|
<div>
|
||
|
|
dir -- Vector3 -- direction from origin. Must be a unit vector. <br />
|
||
|
|
origin -- Vector3 <br />
|
||
|
|
length -- scalar <br />
|
||
|
|
hex -- hexadecimal value to define color ex:0xffff00<br />
|
||
|
|
headLength -- The length of the head of the arrow<br />
|
||
|
|
headWidth -- The length of the width of the arrow
|
||
|
|
</div>
