# OBJ2GLTF

Convert OBJ assets to [glTF](https://www.khronos.org/gltf) 1.0.

## Getting Started

Install [Node.js](https://nodejs.org/en/) if you don't already have it, and then:
```
npm install --save obj2gltf
```
Using obj2gltf as a library:
```javascript
var obj2gltf = require('obj2gltf');
var convert = obj2gltf.convert;
var options = {
    embedImage : false // Don't embed image in the converted glTF
}
convert('model.obj', 'model.gltf', options)
    .then(function() {
        console.log('Converted model');
    });
```
Using obj2gltf as a command-line tool:

`node bin/obj2gltf.js model.obj`

`node bin/obj2gltf.js model.obj model.gltf`

`node bin/obj2gltf.js -i model.obj -o model.gltf`

`node bin/obj2gltf.js -i model.obj -o model.gltf -s`
