Concurrent view of real and virtual environments

An electronic device comprising:

• one or more sensors;
• a non-transitory computer-readable storage medium;
• and
• one or more processors coupled to the non-transitory computer-readable storage medium, wherein the non-transitory computer-readable storage medium comprises program instructions that, when executed on the one or more processors, cause the electronic device to perform operations comprising:
• aligning a 3D representation of a second environment with a 3D coordinate system of a physical environment;
• determining a viewpoint within the 3D coordinate system based on a position of the electronic device within the physical environment;
• and
• presenting a view of the physical environment with an overlaid view of the 3D representation of the second environment based on the viewpoint, wherein the overlaid view of the 3D environment comprises visible lines corresponding to straight and curved edges of structural elements of the second environment, the visible lines defining transparent portions through which at least a portion of the view of the physical environment is visible.

A non-transitory computer-readable storage medium storing program instructions executable via one or more processors, of an electronic device having one or more sensors, to perform operations comprising:

• aligning a 3D representation of a second environment with a 3D coordinate system of a physical environment;
• determining a viewpoint within the 3D coordinate system based on a position of the electronic device within the physical environment;
• and
• presenting a view of the physical environment with an overlaid view of the 3D representation of the second environment based on the viewpoint, wherein the overlaid view of the 3D environment comprises visible lines corresponding to straight and curved edges of structural elements of the second environment, the visible lines defining transparent portions through which at least a portion of the view of the physical environment is visible.
