Constructor Detail

KMLFlyViewController

protected KMLFlyViewController(WorldWindow wwd)

Create the view controller.

Parameters:

wwd - WorldWindow that holds the view to animate. The WorldWindow's view must be an instance of BasicFlyView.

Method Detail

createFlyToLookAtAnimator

protected FlyToFlyViewAnimator createFlyToLookAtAnimator(BasicFlyView view,
                                                         Position lookAtPosition,
                                                         Angle heading,
                                                         Angle pitch,
                                                         double range,
                                                         long timeToMove,
                                                         int altitudeMode)

Create an animator to fly to a LookAt position. The animator is aware of altitude mode and will re-compute the final eye altitude as the animation proceeds to ensure that the final view uses the most accurate elevation data.

Parameters:

view - The view to animate.

lookAtPosition - The position to look at.

heading - Desired heading.

pitch - Desired pitch.

range - Distance from the final eye point to lookAtPosition.

timeToMove - Time to move, in milliseconds.

altitudeMode - Altitude mode of the lookAtPosition (WorldWind.CLAMP_TO_GROUND, WorldWind.RELATIVE_TO_GROUND, or WorldWind.ABSOLUTE).

Returns:

Animator that will animate the view to look at lookAtPosition with the specified heading, pitch, roll, and range.

goTo

protected void goTo(KMLCamera camera)

Animate the view to the position described by a KML Camera.

Specified by:

goTo in class KMLViewController

Parameters:

camera - KML Camera that describes the desired view.

goTo

protected void goTo(KMLLookAt lookAt)

Animate the view to the position described by a KML LookAt.

Specified by:

goTo in class KMLViewController

Parameters:

lookAt - KML LookAt that describes the desired view.
