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

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
