node-stl:使用Node.js解析stl文件并获取体积和重量

node-stl ======== [](https://circleci.com/gh/johannesboyne/node-stl) Parse *STL* files with Node.js and get volume, weight, the bounding box, and the center of mass. ## example ```javascript const NodeStl = require("node-stl"); var stl = NodeStl(__dirname + '/myCool.stl', {density: 1.04}); console.log(stl.volume + 'cm^3'); // 21cm^3 console.log(stl.weight + 'gm'); // 1gm console.log(stl.boundingBox,'(mm)'); // [60,45,50] (mm) console.log(stl.area,'(m)'); // 91.26 (m) console.log(stl.centerOfMass,'(mm)'); // [30,22.5,25] (mm) ``` node-stl recognizes by itself whether it is dealing with an ASCII STL or a binary STL file ## load file from url Use `request` to load a file from url ```javascript const NodeStl = require("node-stl"); const request = require('request'); const requestSettings = { method: 'GET', url: 'https://s3.amazonaws.com/minifactory-stl/WALLY_1plate.stl', encoding: null, }; request(requestSettings, function(error, response, body) { var stl = new NodeStl(body); assert.equal(stl.volume, 21.87511539650792); done(null); }); ``` ## install use [npm/node-stl](https://www.npmjs.com/package/node-stl): ```shell $ npm install node-stl ``` ## license MIT ## version `0.7.1` ## contributors - [alexjv89](https://github.com/alexjv89) - [redwildfire13](https://github.com/redwildfire13) - [lexe11](https://github.com/lexe11) - [Renari](https://github.com/Renari) - [jacekkopecky](https://github.com/jacekkopecky) - [grmmph](https://github.com/grmmph)
