Wormhole

Definition A wormhole is a Visionary object that links two scenes. The source scene is where you place the Wormhole object; the destination scene is what the wormhole connects to.

Concept A wormhole differs from a jump or a hyperlink in the following ways:

• You can carry context information (parameters) from the source scene to the destination scene.
• You see the actual destination scene through the wormhole, not a bitmap representation of the scene. If you are looking at a scene with a wormhole in it, Visionary loads the destination scene as well and displays it through the wormhole.
• Parameterized wormhole. Connects two scenes and passes information from one scene to another. For example, if a source scene displays a scatter chart of automobile sales, each point on the chart can be a wormhole that leads to a destination scene displaying sales data for a particular manufacturer. The manufacturer name is passed as a parameter from one scene to the other through the wormhole, and the graph of sales data displays the information relating to the manufacturer.
