In script, this material allows you to access the distance value at a screen coordinate in the video on a frame using the
getDepth API. Take a look at the Depth Template for an example of how to use this.
Finally, since the Lens runs after the video has been captured, you are able to get the path that the device travels during the video. To use this, in a script, use the
getDevicePathIndex API found in the Device Tracking component. Take a look at the Path Template for an example of how to use this.
Since Lenses for Spectacles run in a different context and not on the live camera, some features are unavailable:
- User context system
- City name
- Time of the recording
- Persistent Storage
- Audio Effect
- Camera Roll Picker

When a feature is unavailable in a Spectacles context, you will see a yellow triangle next to the object containing it in the
Objects panel to remind you.
