Processing Code in Example

 import processing.opengl.*;    PFont font;    void setup(){   size(500,500,P3D);     font=createFont("Franklin Gothic Demi",30,false);   textFont(font,15);  }    void draw(){   background(196);   pushMatrix();   pushStyle();   translate(258,248,0);   float rotX=mouseX/100.0;   float rotY=mouseY/100.0;   rotateX(-rotY);   rotateY(-rotX);   smooth();   noFill();   box(200);   translate(100,100,0);   sphere(100);   popStyle();   popMatrix();   text("mouseX:"+mouseX+" mouseX/100:"+rotX,10,height-30);   text("mouseY:"+mouseY+" mouseY/100:"+rotY,10,height-10);      }    void mouseClicked(){   saveFrame("output.jpg");  }
