Abstract: X3D-UML utilises X3D (eXtensible 3D) to enable standards-based advanced 3D UML visualisations. Using X3D-UML, 3D UML State Machine Diagrams have been evaluated against actual user tasks and data, using the Sequential Evaluation methodology. The results of User Task Analysis, Heuristic Evaluation and Formative Evaluation phases provide clear evidence that the use of UML extended with 3D is a practical solution for visualising complex system behaviour. RoseRT model metrics show between 56%-90% of state machine diagram work would benefit from such 3D UML extensions; hence the 3D improvement can deliver considerable benefit to organisations.

Example X3D-UML State Machine Diagram

Attached is an example 3D UML State Machine as demostrated at MODELS'08. This is one state machine from a tutorial model provided with RoseRT. In reality this is quite a small state machine, commercial models can have as many as 19 diagrams in one state machine.

Installing X3D Browser

To use the attached X3D-UML file you need to install an X3D/VRML browser plug-in to Internet Explorer or Firefox. The best implementation available is from Bitmanagement which is free to test (but comes with a "nag" banner within the scene).

To install the viewer go to the following link and follow the instructions for BS Contact 7.1

Note: BS Contact only works for Windows. For other OS's try Octaga or other browsers from the Web3D list. These will not work as smoothly as BS Contact and certain features will not work at all (though they are improving all the time).

Using the X3D Browser

You can view the file by saving it locally and opening it in just the viewer or drag+dropping it into a webbrowser (to open it via the plugin ).

The browser is a full VR browser with various features available by right-clicking anywhere on the scene. The following actions provide the easiest way to view and navigate the scene from default "Examine" mode:

<esc> key : Position entire scene in view
Mouse Scroll Wheel : zoom in and out
Mouse Left-click drag : Rotate scene left/right + up/down
Click and hold on state machine diagrams to reposition them
"File -> Save State As... to save your layout
"Shift" mouse click to shrink/expand state machine branches
F5 to reload scene
