// Create a new screen object and associate it with a logical name and a
// number.  This number is used as an index to retrieve the AWT GraphicsDevice
// from the array that GraphicsEnvironment.getScreenDevices() returns.
// 
// NOTE: The GraphicsDevice order in the array is specific to the local
// site and display system.
// 
(NewScreen center 0)

// Create a fullscreen window
//
(ScreenAttribute center WindowSize NoBorderFullScreen)

// Set the available image area for the full screen.
// 
(ScreenAttribute center	PhysicalScreenWidth  0.360)
(ScreenAttribute center	PhysicalScreenHeight 0.288)

// Set the TrackerBaseToImagePlate transform for this screen.  The coexistence
// to tracker base transform is identity by default, so the tracker base origin
// and orientation will also set the origin and orientation of coexistence
// coordinates in the physical world.  This is the primary purpose of setting
// this transform when neither head tracking nor multiple screens are being
// used. 
//
// The tracker base and center of coexistence are set here to the middle of the
// screen's image plate.  Their basis vectors are aligned with the image plate
// basis vectors.  The physical eyepoint position will be set relative to
// coexistence coordinates below.
//
(ScreenAttribute center TrackerBaseToImagePlate
                        (Translate 0.180 0.144 0.000))

// Create a view using the defined screen.
// 
(NewView view0)
(ViewAttribute view0 Screen center)

// Set the eyepoint relative to coexistence coordinates.  Here it is set 45cm
// toward the user along +Z.  Skewed projections can be set by by offsetting
// the eyepoint along X and Y.
// 
(ViewAttribute view0 CenterEyeInCoexistence (0.0 0.0 0.45))

// Create a view platform behavior.  Here we use OrbitBehavior, although any
// concrete subclass of the abstract ViewPlatformBehavior with a parameterless
// constructor could be used.  The logical name to assign to this behavior is
// specified by the 2nd argument to the NewViewPlatformBehavior command, while
// the 3rd argument is the name of the ViewPlatformBehavior subclass.  It is
// instantiated through introspection.
// 
// Attributes defined by the abstract ViewPlatformBehavior superclass itself
// can be set directly with the ViewPlatformBehaviorAttribute command.  The
// details of the subclass implementation are not known to ConfiguredUniverse,
// so any configuration information needed by such a subclass is set by the
// ViewPlatformBehaviorProperty command.  The property name specified by that
// command is taken to be a method name of the subclass and invoked through
// introspection.
// 
// View platform behaviors often need sensors or canvases as event sources to
// drive the behavior action.  An implementation of ViewPlatformBehavior always
// gets the current ViewingPlatform through the setViewingPlatform() method.
// The canvases used by the ViewingPlatform can be retrieved by calling its
// getViewers() method and then calling each Viewer's getCanvas3Ds()
// method.  Sensors can be retrived by calling the ViewingPlatform method
// getUniverse(), checking to see if the returned SimpleUniverse is a
// ConfiguredUniverse, and then calling its getNamedSensors() method.
//

// (0.0 0.0 0.0) and a radius of 100 meters.

// Set properties specific to OrbitBehavior.  All arguments following the
// method name are wrapped and passed to the specified method as an array of
// Objects.  Strings "true" and "false" get turned into Boolean, and number
// strings get turned into Double.  Constructs such as (0.0 1.0 2.0) and
// ((0.0 1.0 2.0 0.5) (3.0 4.0 5.0 1.0) (6.0 7.0 8.0 0.0)) get converted to
// Point3d and Matrix4d respectively. Note that last row of a Matrix4d doesn't
// need to be specified; it is implicitly (0.0 0.0 0.0 1.0).
// 
// The REVERSE_ALL flags are usually passed to the OrbitBehavior constructor.
// Since it is being instantiated with its parameterless constructor the
// reverse flags are set here explicitly.
