Animator

Enclosing class:

KMLFlyViewController

protected class KMLFlyViewController.FlyToLookAtAnimator
extends FlyToFlyViewAnimator

A compound animator to animates a FlyView to look from the same orientation as an OrbitView. The animator also takes an altitude mode that applies to the orbit view center position (the LookAt position). If the altitude mode is relative to the surface elevation, the animator will re-compute the final eye position on each iteration to ensure that the animation ends using the most accurate elevation data available.

                           Position lookAtPosition,

                           AngleAnimator rollAnimator)

Create an animator to animate the view to look at a position.

Parameters:

interpolator - Interpolator to control the rate of animation.

targetView - OrbitView that specifies desired heading, pitch, and zoom. The animator may modify this view as the animation proceeds, and the center position is re-calculated with new elevation data.

lookAtPosition - Position to look at.

altitudeMode - Altitude mode of lookAtPosition.

eyePositionAnimator - Animator for eye position.

elevationAnimator - Animator for eye elevation.

headingAnimator - Animator for heading.

pitchAnimator - Animator for pitch.

rollAnimator - Animator for roll.

Method Detail

setImpl

protected void setImpl(double interpolant)

Set the values attached to each of the Animators using the given interpolant.

Overrides:

setImpl in class CompoundAnimator

Parameters:

interpolant - A value between 0 and 1.
