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• Community supported project to improve and add more features to

World Wind Android• NASA providing svn hosting:
