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:
