hi, how can i animate a branching systen, so that the tree looks like growing?
so i would need to put each new branch in a new loop...?
sample of actual code:

1. 
   float r1=0.5,sc;
   void setup()
   {
     size(900,600);
     smooth();
     //noLoop();
   }
   
   void draw()
   {
     //filter(BLUR, 1);
     noStroke();
     fill(255,20);
     rect(0,0,width,height);
     sc=random(0.6,1.9);
     stroke(0);
     strokeWeight(10);
     translate(random(width),random(100)+570);
     branch(0);
     noLoop();
   }
   
   void branch(int recurs){
     if (recurs < 10) {
       line(0,0,0,-height/10);
       {
         translate(0,-height/10);
         rotate(random(-0.3,0.3));    
   
         if (random(1.0) < r1){
           rotate(0.3);
           //scale(0.7);
           sc=random(0.5,0.99);
           scale (sc,sc);
           pushMatrix();
           branch(recurs + 1);
           popMatrix();   
           rotate(-0.6);
   
           pushMatrix();
           branch(recurs + 1);  
           popMatrix();     
           sc=random(3);
           scale (sc,sc); 
                //
         }
         else {
           branch(recurs);
         }
   
       }
     }
   }
   
   
   void mouseReleased(){
     redraw();
   }
   
   
   
   
   

thank you!
