title: Three.js Example code, from StackOverflow, not working
body: <p>I copied and pasted the Three.js code given <a href="https://stackoverflow.com/tags/three.js/info">here</a> into an HTML file and downloaded the <code>three.js</code> package from the website, and configured the <code>&lt;script&gt;</code> tag to point to the location of the file <code>three.min.js</code>. </p>
  
  <p>Nonetheless, when I open the HTML file, it displays a blank white screen.</p>
  
  <p>What am I missing?</p>
