In Google Earth, if you move the mouse over a 3D model (building), it turns light blue. If you click on it, you get a description (or sometimes just an approximate address).
Google Earth plug-in web apps like Monster Milktruck or First Person Cam are wonderful educational tools for exploring an area, and learning about it spatially. For example you are walking or driving around Rome, and you see buildings like the Coliseum or the Forum, but you don't know what they are; so it would be very useful to be able to click on them as you can in Google Earth, and get a description.
Is there any way to do this in the G Earth Plug-in API? I see that a hitTest can tell you whether you clicked on a model, and if so, what the lat/lon of your hit is. But surprisingly, it doesn't tell us which model was hit. Nor can I find any way to look up the model in Google 3D Warehouse using the lat/lon.
Can someone tell me a way to do this? Or is it for sure not allowed?
