공개 메소드들

메소드	설명
App1 ( ) : System	Default constructor.
addManipulationProcessor ( Contact c ) : void	Each Contact gets its own ManipulationProcessor assigned This way we can use the Manipulator data even if there are multiple Contacts
cleanHistory ( int id ) : void	Removes all unnecessary entries from the history Dictionaries
cleanManipulationProcessorList ( List removedContacts ) : void	Removes ManipulationProcessor assigned to removed Contacts
computeAngularVelocity ( Contact currentContact, Contact previousContact, float &angularVelocity, float &angularAcceleration ) : void	Computes the angular velocity and the angular acceleration of a Contact The unit for the velocity is: Rotations / Seconds The unit for the acceleration is: Rotations / Seconds^2
getMotionAcceleration ( int id, float &acceleration, long frameTimestamp ) : void	If possible, computes the motion acceleration This is done by subtracting the preceding Contact velocity from the current contact velocity, devided by the time delta The unit is acceleration is: Screen Dimesion / Seconds^2
getVelocity ( int id, float &velocityX, float &velocityY, InteractiveSurface surface ) : void	Retrieve the movement velocity of a Contact The data is taken from a ManipulationProcessor linked to the Contact The final unit is: SurfaceDimension / Seconds
processContactManipulator ( Contact c, ReadOnlyContactCollection currentContacts, ReadOnlyContactCollection previousContacts ) : void
sendTUIO_2DBlb ( List contacts, ReadOnlyContactCollection previousContacts ) : void	Sends a /tuio/2Dblb message The remote Host is specified in the appConfig The message is built according to TUIO 1.1 specifications (see http://www.tuio.org/?specification)
sendTUIO_2DCur ( List contacts, ReadOnlyContactCollection previousContacts ) : void	Sends a /tuio/2Dcur message The remote Host is specified in the appConfig The message is built according to TUIO 1.1 specifications (see http://www.tuio.org/?specification)

보호된 메소드들

메소드	설명
Draw ( GameTime gameTime ) : void	This is called when the app should draw itself.
Initialize ( ) : void	Allows the app to perform any initialization it needs to before starting to run. This is where it can query for any required services and load any non-graphic related content. Calling base.Initialize will enumerate through any components and initialize them as well.
LoadContent ( ) : void	Load your graphics content.
UnloadContent ( ) : void	Unload your graphics content.
Update ( GameTime gameTime ) : void	Main application Logic We retrieve the current Contacts and send TUIO messages accordingly You can specify via appConfig if you want a Finger Contact to be sent as /tuio/2Dcur or /tuio/2Dblb Sending it as /tuio/2Dblb conserves the Contact size, rotation, angular velocity and angular acceleration

InitializeSurfaceInput ( ) : void	Initializes the surface input system. This should be called after any window initialization is done, and should only be called once.
OnAffine2DDelta ( object sender, Affine2DOperationDeltaEventArgs e ) : void	Extract the Manipulation Data and write it into our Dictionary
OnAffine2DManipulationCompleted ( object sender, Affine2DOperationCompletedEventArgs e ) : void	Unused
OnAffine2DManipulationStarted ( object sender, Affine2DOperationStartedEventArgs e ) : void	Unused
OnApplicationActivated ( object sender, EventArgs e ) : void	This is called when application has been activated.
OnApplicationDeactivated ( object sender, EventArgs e ) : void	This is called when application has been deactivated.
OnApplicationPreviewed ( object sender, EventArgs e ) : void	This is called when application is in preview mode.
SetWindowOnSurface ( ) : void	Moves and sizes the window to cover the input surface.
