Google makes it easier for users to create 3D models on its Google Earth application.
Google is launching their version of Sim City today, Google Building Maker. The tool lets you create buildings for Google Earth. Building Maker lets you pick any building and construct a 3D version of it using photos and building blocks provided by Google.
