Abstract

Described is a method and system providing a dynamic, live (active) surface and/or model elements to complement and enhance what is being modeled or visualized, enabling the addition of new features and functionality to visualization and modeling tools. A dynamic surface is accomplished by extending traditional HTML, rendering APIs and/or components to enable visualization and modeling functionality. The surface background and model elements may comprise HTML elements, and the surface can include a Web site. The model elements are HTML elements layered dynamically atop the surface, as the user interacts with them, and completed designs may be saved in a non-proprietary format, (e.g., HTML). The live surface bases its services on HTML rendering engine services, and further provides a visualization and modeling engine that wraps and extends the rendering engine through multiple interfaces. Interfaces can enumerate modeling elements and their relationships, add, delete or change connections between model elements and states, and initialize the surface, including loading an existing diagram such as saved as an HTML document.

Claims

1. A computer-implemented method, comprising:

providing a surface object having a model element object associated therewith;

providing interfaces to the surface object and the model element object for accessing methods of the surface object and the model element object; and

detecting events at the surface object for viewing or editing the model element object via an interface of the model element object.

2. The method of claim 1 wherein providing the surface object includes providing a rendering engine.

3. The method of claim 2 wherein providing a surface object includes rendering an HTML document via the rendering engine.

4. The method of claim 2 wherein the surface object includes a visualization and modeling engine, and wherein the methods of the surface object are included in the rendering engine and the visualization and modeling engine.

5. The method of claim 1 further comprising, associating the model element object with the surface object.

6. The method of claim 1 wherein detecting events at the surface object includes, receiving events generated via a pointing device.

7. The method of claim 1 wherein detecting events at the surface includes, receiving an event related to a visibility change of the model element object.

8. The method of claim 7 further comprising, changing the visibility of the model element object.

9. The method of claim 1 wherein detecting events at the surface includes, receiving an event related to a zoom percentage change.

10. The method of claim 9 further comprising, changing the displayed size of the model element object.

11. The method of claim 10 wherein changing the displayed size of the model element object includes raising an event at the surface and receiving the event at the model element object.

12. The method of claim 1 wherein detecting events at the surface includes, receiving an event related to a selected or unselected state change of the model element object.

13. The method of claim 1 wherein detecting events at the surface includes, receiving an event related to a resizing of the model element object.

14. The method of claim 1 further comprising, associating another model element object with the surface object.

15. The method of claim 14 wherein associating the other model element object with the surface object includes receiving information corresponding to the other model element being placed upon a visual representation of the surface object.

16. A computer-readable medium having computer-executable instructions for performing the method of claim 1.

17. In a computer-based modeling environment, a system comprising,

a surface, the surface including methods and having at least one interface to those methods;

a model element, the model element including methods and having at least one interface to those methods; and

the surface configured to detect an event and to execute at least one of its methods based on that event to communicate information to the model element, the model element configured to detect the information and to execute at least one of its methods based on the information to perform a modeling-related action.

18. The system of claim 17 wherein the modeling-related action comprises raising another event.

19. The system of claim 17 wherein the modeling-related action corresponds to a state change of the model element.

20. The system of claim 19 wherein the state change of the model element corresponds to changing between hidden and visible states.

21. The system of claim 19 wherein the state change of the model element corresponds to changing between selected and unselected states.

22. The system of claim 19 wherein the state change of the model element corresponds to resizing the model element.

23. The system of claim 17 wherein the surface comprises a rendering engine having a set of interfaces.

24. The system of claim 23 wherein the rendering engine renders an HTML page as a background surface.

25. The system of claim 23 wherein the surface includes a modeling engine having another set of interfaces.

26. The system of claim 17 wherein the model element comprises a node object.

27. The system of claim 17 wherein the model element comprises an arc object.

28. A computer-readable-medium having computer executable instructions, comprising,

initializing a surface having a surface interface;

initializing a model element having a model element interface;

receiving an event at the surface, the event corresponding to a request to perform an action with request to the model element; and

performing the action by communicating from the surface object to the model element via the model element interface.

29. The computer-readable-medium of claim 28 wherein initializing the surface includes rendering a background surface.

30. The computer-readable-medium of claim 28 wherein the background surface comprises HTML.

31. The computer-readable-medium of claim 28 wherein initializing the surface includes accessing content via a URL.

32. The computer-readable-medium of claim 28 wherein the event received at the surface corresponds to a pointing device event.

33. The computer-readable-medium of claim 28 wherein the event received at the surface corresponds to a keyboard event.

34. The computer-readable-medium of claim 28 wherein the event received at the surface corresponds to a request to select the model element.

35. The computer-readable-medium of claim 28 wherein the event received at the surface corresponds to a request to reposition the model element with respect to the surface.

36. The computer-readable-medium of claim 28 wherein the event received at the surface corresponds to a request to resize the model element.

37. The computer-readable-medium of claim 28 wherein the event received at the surface corresponds to a request to negotiate an interconnection to the model element.

38. The computer-readable-medium of claim 28 wherein the event received at the surface corresponds to a request to print a representation of the surface including an area having a representation of the model element therein.

39. The computer-readable-medium of claim 28 wherein the event received at the surface corresponds to a request to save surface data including model element data.

40. The computer-readable-medium of claim 39 wherein the surface data is saved as an HTML document.
