EyeGazeMU

public EyeGazeMU()

Method Detail

copy

public EyeGazeMU copy(AnimationPlayer p)

Description copied from interface: MotionUnit

Create a copy of this motion unit and link it to the animationplayer

Specified by:

copy in interface MotionUnit

Overrides:

copy in class GazeMU

createTMU

public TimedMotionUnit createTMU(BMLBlockPeg bmlBlockPeg,
                                 String i,
                                 String bmlId)

Description copied from interface: MotionUnit

Creates the TimedMotionUnit corresponding to this motion unit

Specified by:

createTMU in interface MotionUnit

Overrides:

createTMU in class GazeMU

i - behaviour id

bmlId - BML block id

Returns:

the TMU

setEndRotation

void setEndRotation(float[] gazeDir)
              throws MUPlayException

Overrides:

setEndRotation in class GazeMU

Parameters:

gazeDir - gaze direction

Throws:

MUPlayException

play

public void play(double t)
          throws MUPlayException

Description copied from interface: MotionUnit

Executes the motion unit, typically by rotating some VJoints

Specified by:

play in interface MotionUnit

Overrides:

play in class GazeMU

Parameters:

t - execution time, 0 < t < 1

Throws:

MUPlayException - if the play fails for some reason

getPredictor

public MotionUnit getPredictor(VJoint vPredict)

Description copied from class: GazeMU

Creates a gaze predictor. The gaze predictor starts at whatever start pose the first call to play on its TMU will set. This also locks the target pos. Since the GazeMU allows flexible start poses, it's not very handy nor needed to use a prediction on any time before the ready sync.

Specified by:

getPredictor in interface MotionUnit

Overrides:

getPredictor in class GazeMU

Parameters:

vPredict - VJoint to execute the prediction on

Returns:

predictor motion unit

getPreferedDuration

public double getPreferedDuration()

Specified by:

getPreferedDuration in interface MotionUnit

Overrides:

getPreferedDuration in class GazeMU

Returns:

Prefered duration (in seconds) of this motion unit, 0 means not determined/infinite
