本文章是基于three.js的编辑器进行源码解析，编辑器的版本是r103dev版本。
首先从感性认识上看看编辑器都包含哪些内容，让我们从three.js-dev\editor\js\Strings.js开始。
Strings.js
包含整个ui中所有控件的名称信息，从中可以看出编辑器都包哪些ui控件、以及一些设置信息。这些控件包含中文、英文支持，现在介绍英文部分。
就整体而言，包含：
- 菜单项 menubar 信息
- 场景sidebar/scene 信息
- 属性sidebar/properties/ 信息
- 对象sidebar/object 信息
- 对象的顶点sidebar/geometry信息
- 对象的材质sidebar/material 信息
- 对象的脚本sidebar/script 信息
- 对象的设置sidebar/settings 信息
- 对象的sidebar/history 信息
- toolbar工具条（选中对象时的平移、旋转、缩放、本地世界矩阵的转换信息）
- 提示viewport/info 信息
