AR position indicator

A system comprising:

• at least one processor configured to perform operations comprising:
• receiving a video that includes a depiction of one or more real-world objects in a real-world environment;
• generating a three-dimensional (3D) model of the real-world environment based on the video;
• determining, based on the 3D model of the real-world environment, that an augmented reality (AR) item has been placed in the video at a particular 3D position;
• identifying a portion of the 3D model corresponding to the real-world environment currently being displayed on a screen;
• determining that the particular 3D position of the AR item in which the AR item was previously placed is excluded from the portion of the 3D model currently being displayed on the screen, such that the AR item is visible in the screen when the 3D model currently being displayed corresponds to the particular 3D position and the AR item is at least partially not visible when the 3D model currently being displayed excludes the particular 3D position;
• and
• in response to determining that the 3D position of the AR item is excluded from the portion of the 3D model, displaying an indicator that identifies the 3D position of the AR item in the 3D model relative to the portion of the 3D model currently being displayed on the screen.

A non-transitory machine-readable storage medium that includes instructions that, when executed by one or more processors of a machine, cause the machine to perform operations comprising:

• receiving a video that includes a depiction of one or more real-world objects in a real-world environment;
• generating a three-dimensional (3D) model of the real-world environment based on the video;
• determining, based on the 3D model of the real-world environment, that an augmented reality (AR) item has been placed in the video at a particular 3D position;
• identifying a portion of the 3D model corresponding to the real-world environment currently being displayed on a screen;
• determining that the particular 3D position of the AR item in which the AR item was previously placed is excluded from the portion of the 3D model currently being displayed on the screen, such that the AR item is visible in the screen when the 3D model currently being displayed corresponds to the particular 3D position and the AR item is at least partially not visible when the 3D model currently being displayed excludes the particular 3D position;
• and
• in response to determining that the 3D position of the AR item is excluded from the portion of the 3D model, displaying an indicator that identifies the 3D position of the AR item in the 3D model relative to the portion of the 3D model currently being displayed on the screen.
