Hi, how can i make some agents to move randomly over a .obj object  in processing?


for example

1. void draw(){
   x = x + random(2) -1 ;
   y = y + random(2) -1 ;
    
     ellipse(x, y , 20 , 20);
    
   }

Instead of moving randomly over a plane i would like that my agents can move randomly over the 3d object

any idea?


thanks


Seb
