title: Processing: How to split screen?
body: <p>I'm trying to create a multi-player game with Processing, but can't figure out how to split screen into two to display different situation of the players?</p>
  
  <p>like in c#,we have 
  <code>Viewport leftViewport,rightViewport;</code>
  to solve the problem.</p>
