RelativisticEffectsManager

java.lang.Object
- gaiasky.util.gravwaves.RelativisticEffectsManager

All Implemented Interfaces:

IObserver
```
public class RelativisticEffectsManager
extends java.lang.Object
implements IObserver
```
Central hub where the parameters of the current relativistic effects (aberration, doppler, grav waves) are updated and served to the renderers.
