ThreeJS-export-OBJ

OBJ exporter for three.js

For a STL exporter see https://github.com/Doodle3D/ThreeJS-export-STL

Example

import 'mrdoob/three.js/three.js';
import { saveAs } from 'file-saver';
import * as exportOBJ from 'Doodle3D/ThreeJS-export-OBJ';

const geometry = new THREE.BoxGeometry(1, 1, 1).clone();
const material = new THREE.MeshBasicMaterial({ color: 0x00ff00 });
const mesh = new THREE.Mesh(geometry, material);

mesh.position.y = 0.5;

const buffer = exportOBJ.fromMesh(mesh).then(blob => {
  saveAs(blob, 'cube.obj');  
});

Installation

Using JSPM (ECMAScript / ES6 Module)

Install the library.

jspm install github:Doodle3D/ThreeJS-export-OBJ

Include the library.

import * as exportOBJ from 'Doodle3D/ThreeJS-export-OBJ';

Using NPM (CommonJS module) IS NOT YET PUBLISHED ON NPM

Install the library.

npm install threejs-export-obj --save

Include the library.

const exportOBJ = require('threejs-export-obj');

API

exportOBJ.fromMesh

data: Buffer = async exportOBJ.fromMesh( mesh: THREE.Mesh )

Creates a .ZIP from THREE.Mesh. The .ZIP contains a .obj file and a .mtl file. The transformation on the THREE.Mesh will be applied to the OBJ geometry.

exportOBJ.fromGeometry

data: Buffer = async exportOBJ.fromGeometry( geometry: THREE.Geometry || THREE.BufferGeometry, [ matrix: THREE.Matrix4, material: THREE.Material ] )

Creates a .ZIP from THREE.Geometry. The .ZIP contains a .obj file and optionally a .mtl file. The transformation from the optional matrix argument will be applied to the geometry.
