Field Detail

_viewScreen

protected ViewScreen3D _viewScreen

The actor displaying the scene, if there is one.

Constructor Detail

GRActor3D

public GRActor3D(CompositeEntity container,
                 java.lang.String name)
          throws IllegalActionException,
                 NameDuplicationException

Create a new GRActor3D in the specified container with the specified name. The name must be unique within the container or an exception is thrown. The container argument must not be null, or a NullPointerException will be thrown.

Parameters:

container - The container.

name - The name of this actor within the container.

Throws:

IllegalActionException - If this actor cannot be contained by the proposed container (see the setContainer() method).

NameDuplicationException - If the name coincides with an entity already in the container.

Method Detail

_addChild

protected void _addChild(javax.media.j3d.Node node)
                  throws IllegalActionException

Add the node argument as a child to the encapsulated Java3D node in this actor. Derived GR Actors should override this method if they aggregate graphical nodes to treat a group as a unit.

Parameters:

node - The node to add.

Throws:

IllegalActionException - Always thrown for this base class.

_getNodeObject

protected abstract javax.media.j3d.Node _getNodeObject()

Return the Java3D node associated with this actor. Derived GR Actors should override this method.

Returns:

The Java3D node associated with this actor.

_setViewScreen

protected void _setViewScreen(GRActor actor)
                       throws IllegalActionException

Set the view screen that this actor is connected to.

Specified by:

_setViewScreen in class GRActor

Parameters:

actor - The view screen actor.

Throws:

IllegalActionException - If the given actor is not a ViewScreen3D.
