Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

threejs-node-exporters

threejs-nodejs-exporters allow you load models and parse ThreeJs data structure and export them to native 3d formats based on NodeJS technology. We removed native browser dependencies and replaced them by substitutes used by NodeJS.

Usage

Basic usage

forked the git repo @injectit/threejs-nodejs-exporters

const THREE = require('three')
const NodeThreeExporter = require('@injectit/threejs-nodejs-exporters')
const fs = require('fs')

//generate cube
const geometry = new THREE.BoxGeometry( 1, 1, 1 )
const material = new THREE.MeshBasicMaterial( {color: 0x00ff00} )
const cube = new THREE.Mesh( geometry, material )

const exporter = new NodeThreeExporter()

const onComplete = buffer => {
  // do what you want with your model ex. save
  fs.writeFileSync('./model.gltf', buffer)
}

// generate buffer
exporter.generate('gltf', cube, onComplete)

Load model from url

const THREE = require('three')
const NodeThreeExporter = require('@injectit/threejs-nodejs-exporters')

const exporter = new NodeThreeExporter()

const onLoad = model => {
  // you can do anything with model ex. change material and add to scene
  const scene = new THREE.Scene()
  model.material = new THREE.MeshBasicMaterial( {color: 0x00ff00} )
  scene.add(model)

  exporter.generate('usdz', scene, buffer=>{...})
}

exporter.load('URL', onLoad)

Load model from file

const THREE = require('three')
const NodeThreeExporter = require('@injectit/threejs-nodejs-exporters')
const fs = require('fs')

const file = fs.readFileSync('./model.obj')

const onParse = model => {
  ...
}

const exporter = new NodeThreeExporter()

exporter.parse('obj', file, onParse)

API

.generate(format, object, onComplete, onError)

  • format(string) - format of generating file, available: usdz, gltf
  • object - Threejs Object3D
  • onComplete(func): callback that will be execute after buffer generate, providing buffer
  • onError(func): callback, execute when generating fails

.load(url, onComplete, onError)

  • url - url to model, available files format: gltf, glb, obj, fbx, stl
  • onComplete(func): callback that will be execute after file load, providing loaded 3D object
  • onError(func): callback, execute when loading fails

.load(format, buffer, onComplete, onError)

  • format(string) - format of parsing buffer, available: gltf, glb, obj, fbx, stl
  • buffer - model file buffer,
  • onComplete(func): callback that will be execute after file parse, providing parsed 3D object
  • onError(func): callback, execute when parse fails

Important! STLLoader generate and returns BufferGeometry, without materials
