title: Label arrows created in ArrowHelper of THREE.js
body: <p>In this question (<a href="https://stackoverflow.com/questions/19564051/labelling-the-vertices-in-axishelper-of-three-js">Labelling the vertices in AxisHelper of THREE.js</a>) is explained how to label axis created with <code>THREE.AxisHelper</code>. I tried to follow the same procedure for <code>THREE.ArrowHelper</code> without sucessfull. So, I'd like to know how to label the arrows I created, just like when indicating the labels of a coordinate system (x,y,z). In this link it how I tried to reproduce the idea: <a href="http://jsfiddle.net/g7oqexr8/" rel="nofollow noreferrer">http://jsfiddle.net/g7oqexr8/</a></p>
