Wow, now you can experience places using Google Maps like you’ve never done before… using WebGL the immersive 3D mapping experience that Google Maps has rolled out is beyond awesome! The 3D transitions and dynamically rendered maps are wild (supported by Chrome 14, Firefox 8 Beta and a few other clients) and will amaze you when transitioning from a 3D view down to StreetView in some special places on the map where Google 3D imagery has been updated (try the Coliseum in Rome for example).

About WebGL… WebGL is a new technology that brings hardware-accelerated 3D graphics to the browser without additional installed software. With WebGL your maps experience is much better with 3D buildings, smoother transitions between imagery and the ability to instantly “swoop” into Street View without a plugin.
