Notes on World Wanderer,
Use the Microsoft Kinect to grab RGBD data points and use the data to form a game map.
Build a database of objects that are found on earth
Use object recognition algorithms to determine when an object appears in a location and use multiple references to ensure that an object looks and behaves like it should
Pull public data on buildings for details on construction and materials
Build every building to spec from the public database and Kinect data.
