Potree是一种基于WebGL的点云数据可视化解决方案
是一套开源的系统，基于Three.js
对点云数据进行了多尺度的管理，在数据传输和可视化上都做了优化
下载
https://github.com/potree/potree
安装依赖
npm install
运行
npm start
（1）生成 build
（2）启动服务器localhost:1234，可以在浏览器中打开 http://localhost:1234/examples/ 查看自带的示例
应用：
使用PotreeJS在Web上展示的点云文件
（1）需要使用PotreeConverter将txt、las等点云数据转换为Potree格式
PotreeConverter下载 https://github.com/potree/PotreeConverter
下载 PotreeConverter 1.7
PotreeConverter harbor.las -o demo --output-format LAS
转出来demo下的目录结构为（2.0.1版本的目录不是面这样的，没找到cloud.js）
（2）前端页面
将 libs、build ，转出来的demo放同一个目录下

缺点：
基于点云格式显示，存在部分失真
las文件
