This is something I’ve been hoping to see for a while now! Masuji Suto and David Sykes have created a small Windows application that uses the GE Plugin to help generate stereographic 3D views. The Stereo GE Browser (available as a zip file) can generate stereo anaglyphs which you can view with cheap red/blue anaglyph glasses, and it also supports several other outputs. Here’s a great example showing New York City (use red/blue glasses):
The great thing about this app (besides that it is free) is that it works in real-time so you can move your view to the way you want it and see the Stereo 3D view at the same time. The app has to show two GE plugins and then screenshot both and combine them and draw the stereo view. So, it’s slower than 1 GE plugin view would be. But, I’m impressed with the speed. If you right click the mouse in the upper view, you get options for how to present the data, and you can save favorite locations.
Here’s what the app looks like when you run it:
I heard about this application at the FreeGeographyTools blog, and his post actually provided full details including screenshots of the menu choices, and information about the different options.
For the record, this isn’t the first time I’ve seen a Stereo3D application for Google Earth. There is a company called Tri-Def which makes a product which makes stereo 3D within GE by intercepting the OpenGL driver. This worked pretty well when I tried their demo a couple of years ago (not sure if it still works today).
