animation - What processing library to use to create simultaneously running renders -

i working on processing (http://processing.org/) , hoping find out whether there library me create 2 different windows rendering 2 views of same scene. there way directly switch 1 another.

i don't know if such library exists processing, can create 2 windows using following code based on a recent processing forum thread

import java.awt.frame; import java.awt.mouseinfo; import java.awt.point; pframe f; secondapplet s;  void setup () {   size(500, 500);   pframe f = new pframe();   frame.settitle("first window"); }   void draw () {   background(255);   s.background(0); // second window background method  // .... //  }  public class pframe extends frame {   public pframe() {     setbounds(0, 0, 500, 500);     s = new secondapplet();     setresizable(false);     add(s);      s.init();      show();     settitle("second window");   } }  public class secondapplet extends papplet {   public void setup() {     size(500, 500);   }   public void draw() {   } } 

then create drawing in each window based on common source of data , methods. i'm no expert, hope helps started project.

note gui libraries such g4p support creation of multiple windows too.

edit: comment related code:

//...// int x=50; void draw () { rect(width/2,0,x,x); s.rect(s.width/2,0,x+10,x+10); } //...//
