World Wind on Android
 Android uses Dalvik, a scaled down version of Java
 Android uses Opengl ES, a scaled down version of Opengl
 World Wind and Android are a good fit.
History:
 Qinetiq creates Qglobe for Android, donates code to NASA
 Features WMS imagery, KML, Icon Layers
 Disables elevation for performance reasons
 Uses OpenGL ES 1.0
 NASA creates World Wind Android
 Features WMS imagery and elevation
 Not much more functionality
 Uses OpenGL ES 2.0
 We want better performance
 Dalvik JVM not as fast as it could be. Will likely be improved in future versions of Android
 C++ is faster as of now.

Future of World Wind on Android
• Long term future, Rewrite code in C++ for better performance and
compatibility with iOS and Windows phone.
•
Some version of C++ and OpenGL ES can be used on most mobile devices.
•
Likely 2+ years away
• Near term future: World Wind Android X
