Class RotationSwitchInterpolator

java.lang.Object

RotationInterpolator

desmoj.extensions.visualization3d.RotationSwitchInterpolator

public class RotationSwitchInterpolator
extends RotationInterpolator

A slightly modified version of RotationInterpolator. It doesn't need much rotational data at the initiation. The alpha, rotation axis and the angles just need to be specified at the start. If the rotation is finished, the calculation will be stopped and the alpha removed.

Constructor Detail

RotationSwitchInterpolator

public RotationSwitchInterpolator(TransformGroup target)

Constructs a RotationSwitchInterpolator.

Parameters:

target - The transformGroup node affected by this transformInterpolator

Method Detail

computeTransform

public void computeTransform(float alphaValue,
                             Transform3D transform)

processStimulus

public void processStimulus(java.util.Enumeration criteria)

stop

public void stop()

Stops the animation

start

public void start(VisualizationClockAlpha alpha,
                  float maximumAngle,
                  Transform3D transformAxis,
                  Transform3D currentTransform)

Sets the rotation data and start the interpolator.

Parameters:

alpha - The alpha which gives the duration

maximumAngle - the ending angle in radians

transformAxis - the transform that defines the local coordinate system in which this interpolator operates. The rotation is done about the Y-axis of this local coordinate system.

currentTransform - the transform that contains the current orientation data of the object.
