title: How to create a soft body in SceneKit
body: <p>So.</p>
  
  <p>After many years of iOS development I said it's time to try to do a little game for myself. Now I chose to do it using Apple's SceneKit since it looks like it provides everything I need.</p>
  
  <p>My problem is that I've stumbled upon a huge problem (for me) and searching on Google doesn't yeld any results.</p>
  
  <p>Any idea how do I go about having an object (a sphere for that matter) that deforms itself, say, because of a gravitational force. So basically it should squash on impact with the ground.</p>
  
  <p>Or, how do I go about deforming it when it collides with other spheres, like a soft beach ball would?</p>
  
  <p>Any starting point along those lines would be helpful. </p>
  
  <p>I can post my code here, but I'm afraid it has nothing to do with my problem since I really don't know where to start.</p>
  
  <p>Thanks!</p>
  
  <p><strong>Update</strong></p>
  
  <p>After doing a bit more reading I think that what I want could be doable with Vertex Shaders. Is that a right path to follow?</p>
