Class java.media.j3d.Screen3D

java.lang.Object
   |
   +----java.media.j3d.Screen3D

public class Screen3D
extends Object

The Screen3D Object contains all information about a particular screen. All Canvas3D objects on the same physical screen (display device) refer to the same Screen3D object. Note that Screen3D has no public constructors---it is obtained from the Canvas3D via the getScreen3D method.

getCoexistenceToImagePlate(Transform3D): Retrieves the coexistence coordinate system to image-plate coordinate system transform and copies that value into the specified Transform3D object.
getHeadTrackerToLeftImagePlate(Transform3D): Retrieves the head-tracker coordinate system to left image-plate coordinate system transform and copies it into the specified Transform3D object.
getHeadTrackerToRightImagePlate(Transform3D): Retrieves the head-tracker coordinate system to right image-plate coordinate system transform and copies it into the specified Transform3D object.
getLeftEyePositionInImagePlate(Point3d): Retrieves the position of the left eye in image-plate coordinates and copies that value into the vector provided.
getPhysicalScreenHeight(): Returns the the screen's physical height.
getPhysicalScreenWidth(): Returns the screen's physical width.
getRightEyePositionInImagePlate(Point3d): Retrieves the position of the right eye in image-plate coordinates and copies that value into the vector provided.
getSize(): Get screen's(imageplate's) width and height in pixels
getTrackerBaseToImagePlate(Transform3D): Retrieves the tracker-base coordinate system to image-plate coordinate system transform and copies it into the specified Transform3D object.
setCoexistenceToImagePlate(Transform3D): Sets the coexistence coordinate system to image-plate coordinate system transform.
setHeadTrackerToLeftImagePlate(Transform3D): Sets the head-tracker coordinate system to left image-plate coordinate system transform.
setHeadTrackerToRightImagePlate(Transform3D): Sets the head-tracker coordinate system to right image-plate coordinate system transform.
setLeftEyePositionInImagePlate(Point3d): Sets the position of the left eye in image-plate coordinates.
setPhysicalScreenHeight(double): Sets the screen's physical height.
setPhysicalScreenWidth(double): Sets the screen physical width.
setRightEyePositionInImagePlate(Point3d): Sets the position of the right eye in image-plate coordinates.
setTrackerBaseToImagePlate(Transform3D): Sets the tracker-base coordinate system to image-plate coordinate system transform.

getSize

 public Dimension getSize()

Get screen's(imageplate's) width and height in pixels

Returns:: dimension screen's width and height in pixels

setPhysicalScreenWidth

 public final void setPhysicalScreenWidth(double width)

Sets the screen physical width.

Parameters:: width - the screen's physical width.

getPhysicalScreenWidth

 public final double getPhysicalScreenWidth()

Returns the screen's physical width.

Returns:: the screen's physical width.

setPhysicalScreenHeight

 public final void setPhysicalScreenHeight(double height)

Sets the screen's physical height.

Parameters:: height - the screen's physical height.

getPhysicalScreenHeight

 public final double getPhysicalScreenHeight()

Returns the the screen's physical height.

Returns:: the screen's physical height.

toString

 public String toString()

Overrides:: toString in class Object

setLeftEyePositionInImagePlate

 public final void setLeftEyePositionInImagePlate(Point3d position)

Sets the position of the left eye in image-plate coordinates. This value determines eye placement when a head tracker is not in use and the application is directly controlling the eye position in image-plate coordinates. In head-tracked mode or when the windowEyePointPolicy is RELATIVE_TO_FIELD_OF_VIEW, this value is derived from other values and is read-only.

Parameters:: position - the new position vector
Throws: RestrictedAccessException: if head tracking is enabled.

setRightEyePositionInImagePlate

 public final void setRightEyePositionInImagePlate(Point3d position)

Sets the position of the right eye in image-plate coordinates. This value determines eye placement when a head tracker is not in use and the application is directly controlling the eye position in image-plate coordinates. In head-tracked mode or when the windowEyePointPolicy is RELATIVE_TO_FIELD_OF_VIEW, this value is derived from other values and is read-only.

Parameters:: position - the new position vector
Throws: RestrictedAccessException: if head tracking is enabled.

getLeftEyePositionInImagePlate

 public final void getLeftEyePositionInImagePlate(Point3d position)

Retrieves the position of the left eye in image-plate coordinates and copies that value into the vector provided.

Parameters:: position - the vector that will receive the position

getRightEyePositionInImagePlate

 public final void getRightEyePositionInImagePlate(Point3d position)

Retrieves the position of the right eye in image-plate coordinates and copies that value into the vector provided.

Parameters:: position - the vector that will receive the position

setTrackerBaseToImagePlate

 public final void setTrackerBaseToImagePlate(Transform3D t)

Sets the tracker-base coordinate system to image-plate 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 only in SCREEN_VIEW mode.

Parameters:: t - the new transform

getTrackerBaseToImagePlate

 public final void getTrackerBaseToImagePlate(Transform3D t)

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

Parameters:: t - the object that will receive the transform

setHeadTrackerToLeftImagePlate

 public final void setHeadTrackerToLeftImagePlate(Transform3D t)

Sets the head-tracker coordinate system to left image-plate 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 only in HMD_VIEW mode.

getHeadTrackerToLeftImagePlate

 public final void getHeadTrackerToLeftImagePlate(Transform3D t)

Retrieves the head-tracker coordinate system to left image-plate coordinate system transform and copies it into the specified Transform3D object.

Parameters:: t - the object that will receive the transform

setHeadTrackerToRightImagePlate

 public final void setHeadTrackerToRightImagePlate(Transform3D t)

Sets the head-tracker coordinate system to right image-plate 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 only in HMD_VIEW mode.

getHeadTrackerToRightImagePlate

 public final void getHeadTrackerToRightImagePlate(Transform3D t)

Retrieves the head-tracker coordinate system to right image-plate coordinate system transform and copies it into the specified Transform3D object.

Parameters:: t - the object that will receive the transform

setCoexistenceToImagePlate

 public final void setCoexistenceToImagePlate(Transform3D t)

Sets the coexistence coordinate system to image-plate coordinate system transform. This transform is derived from head-tracking information and is read-only when head-tracking is enabled. It may be set by the user if head tracking is not enabled.

Parameters:: t - the new transform
Throws: RestrictedAccessException: if head tracking is enabled.

getCoexistenceToImagePlate

 public final void getCoexistenceToImagePlate(Transform3D t)

Retrieves the coexistence coordinate system to image-plate coordinate system transform and copies that value into the specified Transform3D object.

Parameters:: t - the object that will receive the transform
