```javascript
 ....code....

  $("#clearModel").click(function () {
    scene.remove(box);
    box.dispose();
  });
  $("#addModel").click(function () {
    scene.add(box);
  });
}

init();
animate();

```

**The GPU will improve when the 3d model is in the scene.**

**When I remove the model, the GPU is reduced, but there is still some performance consumption.**  
**I call remove() and dispose() , but performanceis only reduced by half**
