title: Three.js How to control position of Vector3 value z using DAT.Gui
body: <p>I am new with three.js and I trying to modify the position value of Z in Vector3 using Dat.Gui. This is my code, but I am not getting any luck.</p>
  
  <pre><code>var zhighpnts = gui.add(parameters, 'x').min(0).max(400).step(.01).name('High Nodes');
  zhighpnts.onChange(function(jar){
          var a = new THREE.Vector3( 400, jar, 400 );
          var b = new THREE.Vector3( 0, 0, 0 );
          var c = new THREE.Vector3( -400, jar, -400 );
      }); 
  </code></pre>
  
  <p>Thanks!</p>
