 public PhysicalEnvironment()

Constructs and initializes a new physical environment object. It creates a default (3) sensors.

 public PhysicalEnvironment(int sensorCount)

Constructs and initializes a new physical environment object.

Parameters:

sensorCount - the number of sensors to create.

 public void setAudioDevice(AudioDevice device)

Set the audio device

Parameters:

 public AudioDevice getAudioDevice()

Gets the audioDevice for this PhysicalEnvironment

Returns:

audio device object associated with this PhysicalEnvironment

 public void setHeadIndex(int index)

Sets the index of the head to the specified sensor index

Parameters:

index - the new sensor index of the head

 public int getHeadIndex()

Gets the sensor index of the head

Returns:

the sensor index of the head

 public void setRightHandIndex(int index)

Sets the index of the right hand to the specified sensor index

Parameters:

index - the new sensor index of the right hand

 public int getRightHandIndex()

Gets the sensor index of the right hand

Returns:

the sensor index of the right hand

 public void setLeftHandIndex(int index)

Sets the index of the left hand to the specified sensor index

Parameters:

index - the new sensor index of the left hand

 public int getLeftHandIndex()

Gets the sensor index of the left hand

Returns:

the sensor index of the left hand

 public void setDominantHandIndex(int index)

Sets the index of the dominant hand to the specified sensor index

Parameters:

index - the new sensor index of the dominant hand

 public int getDominantHandIndex()

Gets the sensor index of the dominant hand

Returns:

the sensor index of the dominant hand

 public void setNonDominantHandIndex(int index)

Sets the index of the non-dominant hand to the specified sensor index

Parameters:

index - the new sensor index of the non dominant hand

 public int getNonDominantHandIndex()

Gets the sensor index of the non-dominant hand

Returns:

 public void setSensor(int index,
                       Sensor sensor)

Set the sensor specified by the index to sensor provided

Parameters:

index - the sensor's index

sensor - the new sensor

 public Sensor getSensor(int index)

Gets the sensor specified by the index

Parameters:

index - the sensor's index

 public void setCoexistenceToTrackerBase(Transform3D t)

Sets the coexistence coordinate system to tracker-base coordinate system transform. If head tracking is enabled, this transform is a calibration constant. If head tracking is not enabled, this transform is not used. This is used in both SCREEN_VIEW and HMD_VIEW modes.

Parameters:

t - the new transform

 public void getCoexistenceToTrackerBase(Transform3D t)

Retrieves the coexistence coordinate system to tracker-base coordinate system transform and copies it into the specified Transform3D object.

Parameters:

t - the object that will receive the transform

 public boolean getTrackingAvailable()

Returns a status flag indicating whether or not tracking is available.

Returns:

a flag telling whether tracking is available

 public void setCoexistenceCenterInPworldPolicy(int policy)

Sets the coexistence center in physical world policy. This setting determines how Java 3D places the user's eye point as a function of head position during the calibration process. The variable can contain one of: View.NOMINAL_SCREEN, View.NOMINAL_HEAD, or View.NOMINAL_FEET. NOTE that a value of View.NOMINAL_SCREEN_SCALED is not allowed for this physical world policy.

Parameters:

policy - the new policy

 public int getCoexistenceCenterInPworldPolicy()

Returns the current coexistence center in physical world policy.

Returns:

one of: View.NOMINAL_SCREEN, View.NOMINAL_HEAD, or View.NOMINAL_FEET

 public int getSensorCount()

Get the current sensor count.

Returns:

the number of sensor objects per PhysicalEnvironment object

 public void setSensorCount(int count)

Set the number of sensor objects per PhysicalEnvironmnet. This is a calibration parameter that should be set before initializing Java 3D.

Parameters:

count - the new sensor count
