Constructor Detail

ALcyLspCameraLinker2D

public ALcyLspCameraLinker2D(ILcyLspMapComponent aMapComponent,
                             Object[] aObjects,
                             ILcdModel[] aModels)

Create a new 2D camera linker, which is used to create and configure new tracking camera's.

Parameters:

aMapComponent - The map component on which this linker will install tracking cameras.

aObjects - The set of object that should be tracked by this camera linker.

aModels - A set of models, denoting for each object of aObjects to which ILcdModel it belongs.

Method Detail

linkTrackingCamera

protected void linkTrackingCamera(Object[] aObjectsToTrack,
                                  ILcdModel[] aModelsToTrack,
                                  ILspView aView)

Create and install a new tracking camera on the given view.

Parameters:

aObjectsToTrack - The objects the camera should track.

aModelsToTrack - The models of those objects.

aView - The view which contains the currently installed camera.

unlinkTrackingCamera

protected void unlinkTrackingCamera(Object[] aObjectsToTrack,
                                    ILcdModel[] aModelsToTrack,
                                    ILspView aView)

Remove the currently installed tracking camera from the given view.

Parameters:

aObjectsToTrack - The set of objects currently tracked by the tracking camera.

aModelsToTrack - The models of those objects

aView - The view on which the tracking camera is installed.

createTrackingPointProvider

protected TLspModelElementTrackingPointProvider createTrackingPointProvider(Object[] aObjectsToTrack,
                                                                            ILcdModel[] aModelsToTrack,
                                                                            ILspView aView)

Create a new tracking point provider, based on the given parameters.

Parameters:

aObjectsToTrack - The objects which the tracking point provider should track.

aModelsToTrack - The models of the objects which the tracking point provider should track.

aView - The view which will be tracked using the tracking point provider returned by this method.

Returns:

A new tracking point provider

createCameraConstraint

protected abstract ALspCameraConstraint<TLspViewXYZWorldTransformation2D> createCameraConstraint(TLspModelElementTrackingPointProvider aTrackingPointProvider,
                                                                                                 ILspView aView)

Create a new camera constraint and return it. The constraint can be created based on the given parameters.

Note that the constraint should not yet be installed on the given camera. Adding and eventually removing this constraint will be done afterwards.

By default this method is called by linkTrackingCamera(Object[], ILcdModel[], ILspView), after a matching tracking point provider has been created.

Parameters:

aTrackingPointProvider - The model element tracking point provider that should be used by the camera constraint.

aView - The view which contains the currently installed, untracked camera.

Returns:

The camera constraint which has been placed on the view's camera.

isLinked

public boolean isLinked()

Description copied from class: ALcyCameraLinker

Check if the camera is linked.

Specified by:

isLinked in class ALcyCameraLinker

Returns:

Whether or not the camera is linked.

isValidViewXYZWorldTransformation

protected boolean isValidViewXYZWorldTransformation(ALspViewXYZWorldTransformation aTransformation)

Determines if the linker is still valid for the given transformation. If not, the linker is unlinked

Parameters:

aTransformation - transfo to check

Returns:

false if the linker should be unlinked

setLinked

public void setLinked(boolean aLinked)

Description copied from class: ALcyCameraLinker

Link or unlink the camera.

Specified by:

setLinked in class ALcyCameraLinker

Parameters:

aLinked - Whether or not to link the camera.

getTrackedObjects

public Object[] getTrackedObjects()

Return the objects which will be tracked by any camera installed by this linker object.

Returns:

The objects which will be tracked by any camera installed by this linker object.

getTrackedModels

public ILcdModel[] getTrackedModels()

Return the models to which the objects, which will be tracked by any camera installed by this linker object, belong to.

Returns:

The models to which the objects, which will be tracked by any camera installed by this linker object, belong to.
