Canvas 3d JS Library

The next demo I am currently working on is a 3d map using the Google Maps API. The reason for this demo is to bring together canvas 3d with other web technologies. So far I can create a route in 3d that is an exact representation of the route Google Maps gives you when asking for directions between locations. The route is a 1:1 scale in the canvas so I needed to set the camera really high up to look down and see the whole map. I then added a zoom function to scale everything so the camera would not have to be set so high. The other reason for the zoom function was the route actually went out of the 3d rendering space. Part of the route was not getting rendered. Besides there is no need for a 1:1 mapping anyways. Next step is to have the camera travel along the 3d map. Then I would like to add features such as 3d Street signs. As the camera moves along the path the user can see the names of upcoming streets. Another feature would be simple 3d buildings that would have the name of the business on them or maybe a bubble or cloud that has the name of the business along the route. Some of the ideas I have floating around in my grey matter.
