title: how to move multiple objects after scene.add(object);
body: <p>I am using Three.js to create an animation of 100 cubes.
  For each cube I set its geometry and material and then add it to the scene with:
  scene.add(cube);
  I have been storing the positions of the cubes in three arrays: cube_x[99] cube_y[99] cube_z[99]</p>
  
  <p>I do not know how to tell the renderer their positions as they are modified. The following works for one cube when I have only one cube in the scene:</p>
  
  <p>cube.position.x=300;
  cube.position.y=000;</p>
  
  <p>I tried making cube into an array to hold the xyz positions of 100 cubes. But I can not seem to call scene.add(cube[i]);</p>
  
  <p>How can I update the position of 100 cubes after scene.add(cube);
  How do I let three.js know which cube I am trying to move?</p>
  
  <p>Thanks - javascript beginner</p>
