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-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 respect to the model element; and

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

2. The computer-readable-medium of claim 1 wherein initializing the surface includes rendering a background surfaces.

3. The computer-readable-medium of claim 1 wherein the background surface comprises HTML.

4. The computer-readable-medium of claim 1 wherein initializing the surface includes accessing content via a URL.

5. The computer-readable-medium of claim 1 wherein the event received at the surface corresponds to a pointing device event.

6. The computer-readable-medium of claim 1 wherein the event received at the surface corresponds to a keyboard event.

7. The computer-readable-medium of claim 1 wherein the event received at the surface corresponds to a request to select the model element.

8. The computer-readable-medium of claim 1 wherein the event received at the surface corresponds to a request to reposition the model element with respect to the surface.

9. The computer-readable-medium of claim 1 wherein the event received at the surface corresponds to a request to resize the model element.

10. The computer-readable-medium of claim 1 wherein the event received at the surface corresponds to a request to negotiate an interconnection to the model element.

11. The computer-readable-medium of claim 1 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.

12. The computer-readable-medium of claim 1 wherein the event received at the surface corresponds to a request to save surface data including model element data.

13. The computer-readable-medium of claim 12 wherein the surface data is saved as an HTML document.

14. 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, wherein detecting events at the surface includes receiving an event related to a zoom percentage change.

15. The method of claim 14, further comprising changing the displayed size of the model element object.

16. The method of claim 15, 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.

17. 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, wherein detecting events at the surface includes receiving an event related to a resizing of the model element object.

18. A computer-implemented method, comprising:

providing a surface object having a model element object associated therewith, the model element designed to be connected with one or more other model element objects;

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.

19. 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 respect to the model element; and

performing the action by communicating from the surface object to the model element via the model element interface, the action including a modeling-related activity with respect to the surface and the model element.

20. The computer-readable medium of claim 19, wherein the activity includes respositioning the model element with respect to the surface.

21. The computer-readable medium of claim 19, wherein the activity includes resizing the model element.

22. The computer-readable medium of claim 19, wherein the activity includes connecting the model element to another model element.

23. The computer-readable medium of claim 19, wherein the activity includes printing a representation of the surface including an area having a representation of the model element therein.

24. The computer-readable medium of claim 19, wherein the activity includes saving surface data including data associated with the model element.

25. The computer-readable medium of claim 19, wherein the surface data is saved in an HTML document.

26. The computer-readable medium of claim 19, wherein the surface comprises a rendering engine having a set of interfaces.

27. The computer-readable medium of claim 19, wherein the surface comprises a visualization engine having a set of interfaces.
