Abstract: An exemplary method includes accessing geometrically located data that represent one or more virtual items with respect to a three-dimensional coordinate system; generating a three-dimensional map based at least in part on real image data of a three-dimensional space as acquired by a camera; rendering to a physical display a mixed reality scene that includes the one or more virtual items at respective three-dimensional positions in a real image of the three-dimensional space acquired by the camera; and re-rendering to the physical display the mixed reality scene upon a change in the field of view of the camera. Other methods, devices, systems, etc., are also disclosed.
