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
separateTextures : true // Don't embed textures in the converted glTF
}
convert('model.obj', 'model.gltf', options)
obj2gltf('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`
`node bin/obj2gltf.js -i model.obj -o model.gltf`
`node bin/obj2gltf.js -i model.obj -o model.gltf -s`
## Usage
###Command line flags:
|Flag|Description|Required|
|----|-----------|--------|
|`-i`|Path to the input OBJ file.| :white_check_mark: Yes|
|`-o`|Directory or filename for the exported glTF file.|No|
|`-b`|Output binary glTF.|No, default `false`|
|`-s`|Writes out separate geometry/animation data files, shader files, and textures instead of embedding them in the glTF file.|No, default `false`|
|`-t`|Write out separate textures only.|No, default `false`|
|`-h`, `--help`|Display help.|No|
|`-i`, `--input`|Path to the obj file.| :white_check_mark: Yes|

|`-b`, `--binary`|Save as binary glTF.|No, default `false`|
|`-s`, `--separate`|Writes out separate geometry data files, shader files, and textures instead of embedding them in the glTF file.|No, default `false`|
|`-t`, `--separateTextures`|Write out separate textures only.|No, default `false`|
|`-c`, `--compress`|Quantize positions, compress texture coordinates, and oct-encode normals.|No, default `false`|
|`-z`, `--optimize`|Use the optimization stages in the glTF pipeline.|No, default `false`|
|`-n`, `--generateNormals`|Generate normals if they are missing.|No, default `false`|
|`--optimizeForCesium`|Optimize the glTF for Cesium by using the sun as a default light source.|No, default `false`|
|`--ao`|Apply ambient occlusion to the converted model.|No, default `false`|
|`-h`|Display help|No|
|`--kmc|Output glTF with the KHR_materials_common extension.|No, default `false`|
|`--bypassPipeline`|Bypass the gltf-pipeline for debugging purposes. This option overrides many of the options above and will save the glTF with the KHR_materials_common extension.|No, default `false`|
|`--checkTransparency`|Do a more exhaustive check for texture transparency by looking at the alpha channel of each pixel. By default textures are considered to be opaque.|No, default `false`|
