= Analysis =

== Overview ==
This task is related to the interaction between the base scene module and other parts of the application.

== Task requirements ==
 * Make a module for the scene library
 * There should be an extension point for concrete implementations
  * Every concrete implementation should provide an extension to this point.
  * The point should be used to make the scene implementation display an object model created by this module.
 * There should be extension points for audio and video players.
  * These are supposed to be implemented by the concrete scenes.
  * It is also possible(although a bit strange) for another bundle to provide an extension to this point.
 * Define the interfaces used for communication with other components
  * How will the page area instruct the scene to build a model
  * How will the scene get information for the elements in the model.

== Task result ==
The result of this task should be source code.

== Implementation idea ==
 * Make a sophie module.
 * Make classes and/or interfaces for the extension point.

== How to demo ==
 * Explain the capabilities of the extension points and interfaces

= Design =
 * Since we need to supply at least two implementations on a scene, we will have an extension point !SceneEngine implementations.
 * !SceneEngine will be an interface with a single method that provides the !JComponent to be drawn in the !PageWorkArea:

{{{
public interface SceneEngine {
	/**
	 * Transforms the object model given in the scene parameter to a graphical representation.
	 * @param scene
	 * 			The Scene object to be visualized
	 * @return A swing component that holds the desired graphical representation.
	 */
	JComponent makeSceneUIComponent(Scene scene);
}
}}}

  * A !BaseSceneModule class should be implemented in the org.sophie2.base.scene module.
   * It should provide extension points for the different implementations of the !SceneEngine.

= Implementation =
 As described in design => [[BR]]
 * [source:trunk/sophie2-platform/modules/org.sophie2.base.scene/src/main/java/org/sophie2/base/scene/BaseSceneModule.java BaseSceneModule]
 * [source:trunk/sophie2-platform/modules/org.sophie2.base.scene/src/main/java/org/sophie2/base/scene/interfaces/SceneEngine.java The extension point interface]
