title: How can I project a group of points in 3D space onto a 2D plane in Matlab?
body: <p>I'm making an animation in Matlab: I have 15 dots moving around in a 3D space. Their XYZ co-ordinates and movement are taken from motion-capture data. I need to show how the dots are moving from the perspective of an observer "in front" of the motion. What I'm trying right now is to create a 2D plane and to move it towards the dots so that they end up "projected" onto it. However, it's not a standard X-Y or Y-Z plane, so I'm having trouble figuring out how to make this work. </p>
  
  <p>How can I make this plane do what I want - or is there another way I should be trying?</p>
