Maya 2 Google Earth
The people over at Eyebeam recently launched a new tool, entitled Maya 2 Google Earth. It's an open-source, cross-platform tool that allows you to export 3D models as a single Google Earth Placemark (KML) file. The project was inspired by the Open GL extraction utility OGLE (also by Eyebeam), which allows for the capture and re-use of 3D geometry data from 3D graphics applications running on Microsoft Windows.
Some of the potential uses for Maya2GoogleEarth are:
-Remix or augment city architecture, with your own creations
-Extract your in-game character with OGLE and bring them into Google Earth
-Design buildings and then show them at their correct geographic location
They've even stated that the first person to have Godzilla attacking Tokyo will have it posted to the site.
