- Method Detail
  - getFactory
```
StereoDeviceFactory getFactory()
```
    Return the factory used to create this device.
  - dispose
```
void dispose()
```
    Disposes this StereoDevice, if valid.
    Implementation shall stop sensors and free all resources.
  - isValid
```
boolean isValid()
```
    Returns true, if instance is created and not disposed, otherwise returns false.
  - getPosition
```
PointImmutable getPosition()
```
    If operation within a device spanning virtual desktop, returns the device position.
    Otherwise simply 0/0.
  - getSurfaceSize
```
DimensionImmutable getSurfaceSize()
```
    Returns the required surface size in pixel in target space.
  - getRequiredRotation
```
int getRequiredRotation()
```
    Returns the CCW rotation as required by this display device.
  - getDefaultEyePositionOffset
```
float[] getDefaultEyePositionOffset()
```
    Return the device default eye position offset for #createRenderer(int, int, float[], FovHVHalves[], float).
    Result is an array of float values for
    
    right (positive)
    
    up (positive)
    
    forward (negative)
    Returns:
  - getDefaultFOV
```
FovHVHalves[] getDefaultFOV()
```
    Returns the device default FovHVHalves for all supported eyes in natural order, i.e. left and right if supported.
    Monoscopic devices return an array length of one, without the value for the right-eye!
  - getLocationSensorParams
```
LocationSensorParameter getLocationSensorParams()
```
    Returns the LocationSensorParameter of the device if SENSOR_POSITION is supported, otherwise returns null.
  - resetLocationSensorOrigin
```
void resetLocationSensorOrigin()
```
    Sets the location sensor's origin of this device to the current position.
    In case SENSOR_POSITION is not supported, this method is a no-op.
  - startSensors
```
boolean startSensors(int desiredSensorBits,
                     int requiredSensorBits)
```
    Start desired and required sensors. Returns true if action was successful, otherwise false.
    Method fails if required sensors are not supported.
    
    Parameters:
    
    desiredSensorBits - the desired optional sensors
    
    requiredSensorBits - the required sensors
    
    See Also:
    
    stopSensors(), getSensorsStarted(), getSupportedSensorBits(), getEnabledSensorBits()
  - stopSensors
```
boolean stopSensors()
```
    Stop sensors. Returns true if action was successful, otherwise false.
    
    See Also:
    
    startSensors(int, int), getSensorsStarted(), getSupportedSensorBits(), getEnabledSensorBits()
  - getSensorsStarted
```
boolean getSensorsStarted()
```
    Return true if sensors have been started, false otherwise.
    
    See Also:
    
    startSensors(int, int), stopSensors(), getSupportedSensorBits(), getEnabledSensorBits()
  - getSupportedSensorBits
```
int getSupportedSensorBits()
```
    Returns the supported sensor capability bits, e.g. SENSOR_ORIENTATION, SENSOR_POSITION of the StereoDevice.

    startSensors(int, int), stopSensors(), getSensorsStarted(), getEnabledSensorBits()
  - getEnabledSensorBits

int getEnabledSensorBits()
```
    Returns the actual used sensor capability bits, e.g. SENSOR_ORIENTATION, SENSOR_POSITION in case the device supports them and if they are enabled.

    startSensors(int, int), stopSensors(), getSensorsStarted(), getSupportedSensorBits()
  - getEyeRenderOrder
```
int[] getEyeRenderOrder()

```
    Returns the recommended distortion compensation bits for the StereoDeviceRenderer, e.g. StereoDeviceRenderer.DISTORTION_BARREL, StereoDeviceRenderer.DISTORTION_CHROMATIC StereoDeviceRenderer.DISTORTION_VIGNETTE.
    User shall use the recommended distortion compensation to achieve a distortion free view.

int getMinimumDistortionBits()
```
    Returns the minimum distortion compensation bits as required by the StereoDeviceRenderer, e.g. StereoDeviceRenderer.DISTORTION_BARREL in case the stereoscopic display uses [a]spherical lenses.
    Minimum distortion compensation bits are being enforced by the StereoDeviceRenderer.
