Appl. No.:

09/304230

Inventors:

Daniel D. Silva - San Rafael CA
Gary S. Yost - Mill Valley CA
Phillip Miller - Petaluma CA

Assignee:

Autodesk, Inc. - San Rafael CA

International Classification:

G06T 1700

US Classification:

345420

Abstract:

A mechanism for depicting a plurality of graphical components is provided. According to an aspect of the present invention, a graphical component hierarchy is displayed. A graphical component hierarchy includes graphic nodes that each correspond to a graphical component, links between graphic nodes, and images associated with graphic nodes. A link between graphical components represent manipulations performed between the graphical components. The graphical component hierarchy includes images for each graphical component, graphically representing how they affect a final image at various stages.

International Classification:

G06T 1740

US Classification:

345619, 345645, 345650, 345661, 345676

Abstract:

A three dimensional (3D) modeling system for generating a 3D representation of a modeled object on a display device of a computer system. The modeled object is represented by an initial definition of an object and a set of modifiers. Each modifier modifies some portion of the definition of an object that may result in a change in appearance of the object when rendered. The modifiers are ordered so that the first modifier modifies some portion of the initial definition of the object and produces a modified definition. The next modifier modifies the results of the previous modifier. The results of the last modifier are then used in rendering processes to generate the 3D representation. Each modifier is associated with a three dimensional representation so that the user can more easily visualize the effect of the modifier.

International Classification:

G06T 1500

US Classification:

345420

Abstract:

A caching system for a 3D modeling system. Intermediate channel results, created during the generation of a representation of an object, are cached. The caching increases the speed of system. In particular, the representation of the object is generated in multiple channels, each channel representing some portion of that representation. Intermediate channel results are generated in each channel by elements in that object's list of modifiers. Depending on for how long these intermediate channel results are valid, the intermediate channel results may or may not be cached. For example, if it is determined that one set of intermediate channel results will be valid for a predetermined period of time, while the next intermediate channel results in that channel will not be valid for a predetermined period of time, then the intermediate channel results are cached.

International Classification:

G06F 314

US Classification:

345357

Abstract:

A graphical user interface ("GUI") incorporating one or more subpanels. Each subpanel has a presentation control and can have one or more GUI objects displayed on the computer screen. Each subpanel may be toggled between an expanded state or a collapsed state by operating the presentation control. Expanding and collapsing the subpanels changes the appearance and the functionality of the GUI, but the size of area of the screen used by the subpanels remains unchanged.

International Classification:

G06T 1100

US Classification:

345428

Abstract:

A system to permit a designer to select the minimum scene refresh rate or animation redraw rate acceptable by the designer. The system also incorporates a selection of presentation methods for the three-dimensional objects in a scene, arranged in decreasing fidelity, and consequently in computational complexity, as fall back positions for the general rendering technique. Using the designer's selected refresh rate as a target, the system attempts to use the highest quality rendering technique selected by the designer. If the computational complexity of the scene causes the refresh rate of the scene to fall below the minimum acceptable level selected by the designer, the system selects the next lower rendering option selected by the designer, thus degrading the presentation quality of the scene and simultaneously reducing the computational complexity of the task.
