title: Having an object follow the graph of a Parametric Function with THREE.js
body: <p>In THREE.js I have created a webpage that graphs parametric equations for viewing with a VR headset, and I'm trying to determine a way to create an interesting demo for it. My goal is to create a sort of rollercoaster ride, where the camera follows along the function. </p>
  
  <p>The parametric equation function in my code returns Vector3's that create the graph, so I assume this would be a good place to get positions for the rollercoaster. However, I am unfamiliar with animation. How can I make my camera, or any object for that matter, follow these vectors?</p>
