# Easy - Head Visualization

At this stage, it is assumed that you have completed the [3D Face Reconstruction](https://docs.metahumansdk.io/service-apis-for-creating-virtual-avatars/getting-started/3d-face-reconstruction) and [3D Hair Reconstruction](https://docs.metahumansdk.io/service-apis-for-creating-virtual-avatars/api-methods/3d-hair-reconstruction) piplines and obtained `uv.png` , `head_config.json` and `head.glb` files.

    -H 'Content-Type: multipart/form-data' \
    -F "token=$token" \
    -F 'head_uv=@uv.png;type=image/png' \

    -F 'custom_models=@hair.glb;type=image/png' \
    -F 'add_facs=true' > head.glb
```

{% endtab %}

{% tab title="python" %}

```python

import requests

token = "ENTER_YOUR_TOKEN"

if __name__ == "__main__":
    service_url = "https://api.metahumansdk.io/glb_const"
    service_headers = {'accept': 'application/json'}
    
    with open('uv.png', 'rb') as out:
        head_uv = out.read()
    with open('head_config.json', 'r') as out:
        head_config = json.loads(out.read())
    with open('hair.glb', 'rb') as out:
        custom_hair = out.read()

    files = {
        'token': (None, token),
        'head_uv': ('head_model', head_uv, 'image/png'),
        'head_config': ('head_config', json.dumps(head_config), 'application/json'),
        'custom_models': ('custom_models', io.BytesIO(custom_hair), 'application/json'),
        'add_facs': (None, True),
    }

    response = requests.post(service_url + "/assemble", headers=service_headers, files=files)
    assert (response.status_code == 200)
 
    with open("head.glb", "wb") as f:
        f.write(response.content)

```

{% endtab %}
{% endtabs %}

After completing all stages, you will get a GLB model `head.glb` .
