我如何销毁THREEJS场景？ [英] How can I destroy THREEJS Scene?

问题描述

问题很简单：我怎样才能销毁场景？从场景中移除所有组件？

我需要销毁场景，因为我 not 想要将任务委派给垃圾收集器。

解决方案

我使用过这个：

  cancelAnimationFrame（this.id）; //停止动画
 this.renderer.domElement.addEventListener（'dblclick'，null，false）; //删除侦听器来渲染
 this.scene = null; 
 this.projector = null; 
 this.camera = null; 
 this.controls = null; 
 empty（this.modelContainer）; 
  

空方法是jQuery空的替代方法，您可以使用它：

  function empty（elem）{
 while（elem.lastChild）elem.removeChild（elem.lastChild）; 
} 
  

I created a Threejs Scene, adding camera, lights and various objects.

The question is simple: how can I destroy scene? Removing from scene all components?

I need to destroy scene because and I do not want to delegate the task to the garbage collector.

解决方案

I used this:

    cancelAnimationFrame(this.id);// Stop the animation
    this.renderer.domElement.addEventListener('dblclick', null, false); //remove listener to render
    this.scene = null;
    this.projector = null;
    this.camera = null;
    this.controls = null;
    empty(this.modelContainer);

The method empty is a substitute to jQuery empty, you can use it:

function empty(elem) {
    while (elem.lastChild) elem.removeChild(elem.lastChild);
}
