The new beta release of the OpenGL API-accelerated Google Earth 4, uses the KML2.1 file format. KML 2.1 adds support for regions to allow for culling and LOD, as well as streaming of very large datasets; textured 3D models that can be imported using the COLLADA interchange format, incremental updates for adding and deleting KML data in real time, image overlays, and more. With support for COLLADA, content developers can use popular 3D modeling applications including Maya, SoftImage|XSI, 3ds Max, Blender, and Sketchup to create sophisticated models with textures, export them as COLLADA, and then import or drag and drop them into Google Earth. This greatly expands the market for 3D visualization. See the KML 2.1 tutorial for more details on the new features..
