Technological demo of OpenGL ES 2 for Android platform. It reads public NORAD satellite database and shows the satellite positions and altitude related to Earth in the form of beams (the height of the beam represents the relative altitude).
NOTE: The project has been moved to GitHub: https://github.com/nuald/glSatellite-Demo The old one stays here just for the historical reasons.
The 3D features present:
- OpenGL ES 2;
- rotating, multi-touch zooming and moving the globe;
- stars on a fixed background;
- each satellite is represented by a beam with a unique color;
- identifying the corresponding satellite if a beam has been tapped (based on color picking method).
Additionally to 3D features presented the application is:
- using NDK with C++11 features compiled by LLVM clang;
- mixing Java views with OpenGL views (Java is used for settings activity, information and ads panels);
- using Android custom message queue to send asynchronous messages from Java to JNI
Features
