the following code can be modified to switch up the animation settings

function animate()
  {
    mesh[0].rotation.x+=0.1;
    mesh[2].rotation.z+=0.1;
    mesh[2].rotation.y+=0.1;
    mesh[1].rotation.z+=.2;
    requestAnimationFrame(animate);
    renderer.render(scene,camera);

    mesh.forEach(m=>{
      m.position.y -= fallspeed;
      if(m.position.y < -bound){
        m.position.y = bound;
      }
    });
  }
