International Classification:

G06T 17/20

US Classification:

345423000

Abstract:

The present invention consists of an evaluation engine, which is a system for evaluating the state of an animation at a specific time where secondary animation may be derived from the state of the animation at another time. Unlike DAG-based systems where time is another variable, time is external to the evaluation engine so that it can easily evaluate alternate times and even entire simulations. It also comprises meshes which support instancing and edge weights, and which employ and extensible system of polygon types to support subdivision surface approximation using a set of bi-quadratic patches which solve quickly. The meshes can also be animated by the evaluation engine using a mesh stack, which has multiple evaluation paths for quickly computing mesh attributes without performing a full evaluation.

Abstract:

The present invention allows users to customize user interfaces within software programs on the fly. By customizing user interfaces users can streamline their own work process, particularly when the user is dealing with large amounts of data. In addition to customizing user interfaces, the present invention also allows users to more easily select portions of an object with the select more command and to more easily enter exact numeric values with detents on mouse input.
