Concurrent view of real and virtual environments

Abstract

Various implementations disclosed herein include devices, systems, and methods that enable concurrent viewing of both virtual and real 3D environments. This may involve presenting a virtual environment overlaying a physical environment. For example, a process may align a 3D representation of a second environment with a 3D coordinate system of a physical environment and determining a viewpoint within the 3D coordinate system based on a position of the electronic device within the physical environment. The process may further include presenting a view of the physical environment with an overlaid view of the 3D representation of the second environment based on the viewpoint. The overlaid view of the 3D environment includes visible lines defining transparent portions through which at least a portion of the view of the physical environment is visible.
