title: Adding animation to an 3d model via ARKit
body: <p>I have a 3d model of a human being standing. I implemented it into an project using arkit and can place it somewhere in the room. So far so good, but I would like to add an animation to the 3d model. For example when I press the <code>buttonDance</code> that it starts dancing. Not to move it up and down, but to add an animation to it.</p>
  
  <p>What are keywords to make this work or does anyone have a brief way of doing this? Maybe what software to use or is it possible within <code>sceneKit</code> maybe?</p>
