Export Buildings From Google Earth I found this technique of extracting buildings from Google Earth for use in any 3D modeling programs on http://forum.sketchup.com/showthread.php?t=74242. By following the instructions, installing the freeware applications, putting the right system files and overwrites where they need to be in Google Earth folder (all available on at the forum), going in Google Earth and extracting the buildings from a city, opening the .obj file in Rhino, and exporting it as a .dwg, you can have basic polygonal solids of whatever cities that are available on Google Earth. Japan has a lot now in Google Earth; here’s some renders of the Omotesand site given for the Tokyo House project, as well as some of Manhattan that I used for the skyscraper work:
I’ve copied the relevant text from the forum for how to do this here:
<“This particular technique only works, as far as I know, with a PC, and you will need the applications GLIntercept and OGLE: http://glintercept.nutty.org/download.html http://ogle.eyebeamresearch.org/download What you do with these programs is literally to intercept the OpenGL instructions to your video card from Google Earth, and then convert them to a standard mesh. Obviously, for this to work you have to have Google Earth running in OpenGL mode, not DirectX. Also, as noted in the OGLE instructions: "Some applications do not seem to want to function (i.e. they crash!) with GLIntercept if the real OpenGL32.dll is in the system location. If you are having weird problems, try the following: 1. Copy the sytem dll (most likely C:\WINDOWS\system32\opengl32.dll) to your app's directory (name it opengl32.orig.dll or some such) 2. Set GLSystemLib = "opengl32.orig.dll"; in your gliConfig.ini file." Google Earth is one of the applications that require that procedure; if you don't copy the system .dll into the GE directory, GE will simply not work at all (if you have placed the GLIntercept files in the GE directory). Follow this and the other directions with GLintercept and OGLE very carefully. The end result will be an .obj file that includes what was visible in your screen in GE, along with some odd artifacts. To get this file into SketchUp, you'll have to translate the .obj into something SU opens. Some modelers seem to have difficulty with .obj files created by OGLE, notably 3DS Max. But I have been able to open them just fine with Rhino (and re-export them as .dwg files to SU), and you might try any of the various free
