    Abstract: An occlusion detection system to perform operations that include: capturing image data that depicts an environment at a client device, the environment including a target object at a position within the environment; causing display of a presentation of the environment at the client device, the presentation of the environment including a display of the target object at the position within the environment; detecting a first attribute of the display of the target object at the client device; performing a comparison of the first attribute of the display of the target object and a second attribute associated with the target object; and detecting an occlusion based on the comparison.

    Abstract: A crowd-sourced modeling system to perform operations that include: receiving image data that comprises image attributes; accessing a 3D model based on at least the image attributes of the image data, wherein the 3D model comprises a plurality of parts that collectively depict an object or environment; identifying a change in the object or environment based on a comparison of the image data with the plurality of parts of the 3D model, the change corresponding to a part of the 3D model from among the plurality of parts; and generating an update to the part of the 3D model based on the image attributes of the image data.

    Abstract: Systems and methods are provided for determining a location of a selection in a space viewable in a camera view on a display of a computing device, detecting movement of the computing device, and generating a path based on the location of the selection and the movement of the computing device. The systems and methods further provide for generating a three-dimensional (3D) mesh along the path, populating the 3D mesh with selected options to generate a 3D paint object, and causing the generated 3D paint object to be displayed. The systems and methods further provide for receiving a request to send a message comprising an image or video overlaid by the 3D paint object, capturing the image or video overlaid by the displayed 3D paint object, generating the message comprising the image or video overlaid by the 3D paint object, and sending the message to another computing device.

    Abstract: Method for creating marker-based shared augmented reality (AR) session starts with initializing a shared AR session by a first device and by a second device. The first device displays on a display a marker. The second device detects the marker using a camera included in the second device and captures an image of the marker using the camera. The second device determines a transformation between the first device and the second device using the image of the marker. A common coordinate frame is then determined using the transformation, the shared AR session is generated using the common coordinate frame, and the shared AR session is caused to be displayed by the first device and by the second device. Other embodiments are described herein.
