ABSTRACT:

FIELD OF THE INVENTION
This invention relates generally to the animation of computer models, and more particularly to the animation of computer models in low-bandwidth situations.
BACKGROUND OF THE INVENTION
In one type of computer animation, a number of frames of a computer model are generated, such that displaying the frames in succession gives the appearance that the model is animated. However, with the increasing popularity of low-bandwidth situations such as dial-up connections to the Internet, this type of animation is problematic. A dial-up connection to the Internet, for example, may only provide a throughput of 33,600 bits per second (bps). Having to receive a number of frames of a computer model over a low-bandwidth Internet connection, each of which may consume a relatively large number of data, means that the animation may take several minutes to download prior to the displaying of the animation being able to take place. Where there are a number of different animations to be downloaded for a given web page, for example, the overall effect is to negatively impact the experience of viewing the web page by a user.
For these and other reasons, there is a need for the present invention.
SUMMARY OF THE INVENTION
In one embodiment, a computer-implemented method first generates a noise model having a number of dimensions one greater than a number of dimensions of a source model. The source model is then perturbed to introduce animated distortion into the source model. This is accomplished by utilizing one of a plurality of frames of the noise model, where each frame has a number of dimensions equal to the number of dimensions of the source model. The perturbed source model is then displayed on a display device. In one embodiment, perturbation and displaying of the source model are repeated, utilizing different frames of the noise model.
