hello

for developping my project
http://earth.1000lieues.net

I have found a method to call to the Google earth API
(alas under windows only)
to be able to get/set the camera position
loading kml data or other stuffs

you need the jacob.dll and jar
download here  http://danadler.com/jacob/

special usage :

- during the developpement
you have to put the both files
jacob.dll
jacob.jar
in a code folder of your sketch folder

- for building application
to avoid an error, move jacob.dll in the root sketch folder

after building, copy the dll at the same level of .exe


an exemple code :

////
//Flying over Gao
//by cdriko
void draw(){

 ///definition of values  
 float tilt =15;
 float heading = 0;
 float sec=(millis()/3000.);
 float longitude = 0.051*cos(sec);
 float latitude=16.22+(0.051*sin(sec));
 float altitude=10000;

 ///call to googleEarth
 Dispatch googleEarth = new Dispatch("GoogleEarth.ApplicationGE");

 Dispatch.call(googleEarth,"SetCameraParams",new Variant(latitude),new
   Variant(longitude),new Variant(altitude),new Variant(1),new
   Variant(100),new Variant(tilt),new Variant(heading),new Variant(5));

}
//////



you can found more infos about the fonctionality of api here:
http://groups.google.com/group/kml-support-com-api/topics?hl=en

and the api doc :
http://earth.google.com/comapi/interfaceIApplicationGE.html

hello
verify if you have GoogleEarth opened before launching the sketch.
and try various positions for dll and jar (inside code folder, at the same level of sketch, and [with the last version of processing] in the library folder of your sketchbook)
It's since a long time that I don't used this dll, but, maybe try to explicit import, like another library :

Code:

import com.jacob.com.*;
import com.jacob.activeX.*;
