Snapchat introduces a new 3D camera mode, which adds depth to the photos you take with front-facing cameras on some phones. The 3D camera function can be used to create photos that change in appearance based on how a person holds their phone.
This feature was made possible by the dual front-facing cameras of today’s smartphones. With this, the new 3D camera mode will only be available on select devices (such as iPhone X and above). However, each phone can receive and interact with the new 3D Snapchat photos.
