title: Three JS - Find all points where a mesh intersects a plane
body: <p>I have created a three.js scene that includes a plane that intersects a mesh. What I would like to do is get an array of points for all locations where an edge of the mesh crosses the plane. I have had a good look for solutions and can't seem to find anything. </p>
  
  <p>Here is an image of what I currently have:</p>

  <p>And here I have highlighted the coordinates I am trying to gather:</p>

  <p>If anybody can point me in the right direction, that would be most appreciated.</p>
  
  <p>Thanks,</p>
