Abstract: Various implementations provide a view of a 3D environment including a portal for viewing a stereo item (e.g., a photo or video) positioned a distance behind the portal. One or more visual effects are provided based on texture of one or more portions of the stereo item, e.g., texture at cutoff or visible edges of the stereo item. The effects change the appearance of the stereo item or the portal itself, e.g., improving visual comfort issues by minimizing window violations or otherwise enhancing the viewing experience. Various implementations provide a view of a 3D environment including an immersive view of a stereo item without using portal. Such a visual effect may be provided to partially obscure the surrounding 3D environment.

This involves determining a 2D location of a line segment corresponding to an edge of an object based on a light-intensity image, determining a 3D location of a plane based on depth values (e.g., based on sampling depth near the edge/on both sides of the edge and fitting a plane to the sampled points), and determining a 3D location of the line segment based on the plane (e.g., by projecting the line segment onto the plane). The devices, systems, and methods may involve classifying an edge as a particular edge type (e.g., fold, cliff, plane) and detecting the edge based on such classification.

Abstract: Various implementations use object information to facilitate a communication session. Some implementations create a dense reconstruction (e.g., a point cloud or triangular mesh) of a physical environment, for example, using light intensity images and depth sensor data. A less data-intensive object information is also created to represent the physical environment for more efficient storage, editing, sharing, and use. In some implementations, the object information includes object attribute and location information. In some implementations, a 2D floorplan or other 2D representation provides object locations and metadata (e.g., object type, texture, heights, dimensions, etc.) provide object attributes. The object location and attribute information may be used, during a communication session, to generate a 3D graphical environment that is representative of the physical environment.
