Spectacles 3 is the latest version of Spectacles sunglasses with dual cameras designed to capture the world in 3D. When building for Spectacles, a depth map of the scene, as well as the path which the video travels through is available to use in Lenses. 

Creating Lenses for Spectacles

To enable your Lenses to work with Spectacles, first open the Project Info window by pressing the Project info button found in the top left corner of Lens Studio

Then, in the pop up window, in the “Lens is Made” for section, enable the checkbox next to 

“Spectacles 3 😎”

Differences in Lenses for Spectacles

Features Enabled

Lenses for Spectacles have unique advantages that allows you to make new types of experiences. 

Depth Setter

With Spectacles enabled, you are able to occlude your scene based on the depth information collected in the Spectacles video. To do this, in the Objects panel, press +, and select Depth Setter. 

Your Depth Setter object should be placed above the objects you want to occlude in the Objects panel. 

Tip
You can add the Depth Setter component through the Inspector panel as well. In general, you will want to add the Depth Setter component to the perspective Camera object. 

Depth Material

Additionally, you can add a material that represents the depth map of the Spectacles video. To do this, in the Resources panel, press + > Spectacles Depth.

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. 

Device Path

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 getDevicePath and 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

• Altitude

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.
