Package gaiasky.scenegraph.camera

Class SpacecraftCamera

java.lang.Object

gaiasky.scenegraph.camera.AbstractCamera

gaiasky.scenegraph.camera.SpacecraftCamera

All Implemented Interfaces:

IObserver, ICamera

public class SpacecraftCamera
extends AbstractCamera
implements IObserver

Implements a spacecraft-like movement. The spacecraft is modeled as a rigid solid and it has a mass and an engine model. The rest is physics.
