Class MovementPathInterpolator

java.lang.Object

TransformInterpolator

desmoj.extensions.visualization3d.MovementPathInterpolator

public class MovementPathInterpolator
extends TransformInterpolator

An interpolator which realize the 3-phase-translation. The translation is divided into 3 phases:
- The acceleration phase
- The maximum speed phase
- The deceleration phase
The translation behavior is defined over the speed and duration of each phase.

Constructor Detail

MovementPathInterpolator

public MovementPathInterpolator(TransformGroup target,
                                TransformGroup orientationTarget)

Creates a MovementPathInterpolator.

Parameters:

target - The transformGroup node affected by this transformInterpolator

orientationTarget - The TransformGroup responsible for the orientation.

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[] durationKnots,
                  float[] speedKnots,
                  Point3f[] positionKnots)

Sets the movement data and start the interpolator.

Parameters:

alpha - The alpha which gives the duration

durationKnots - A float[3] array which describes the duration of the 3 phases movement.

speedKnots - A float[3] array which describes the speed of the 3 phases movement.

positionKnots - An array of points which describe the route of the movement.

startWithFocusOnTrack

public void startWithFocusOnTrack(VisualizationClockAlpha alpha,
                                  float[] durationKnots,
                                  float[] speedKnots,
                                  Point3f[] positionKnots,
                                  Vector3d frontSideVec)
