Data compression through motion and geometric relation estimation functions

摘要

A computing-device implemented method for compressing a data model, where such devices include a computer, personal digital assistant (PDA), home appliance, and the like. The data includes bandwidth intensive information such as that used in video conferencing, MPEG and equivalent types of digital video encoding, multi-media data transfers, and interactive gaming. In one implementation, a 3D model has objects defined therein. Each object is defined by plural data points that are transferred from a data provider to a recipient. Typically the provider and recipient are in communication over a network. For a first and a second data point defined in the model, first offsets are determined from the first data point for the second data point. The second data point can then be re-coded in terms of the determined first offsets. The first offsets are coded to require less data storage than required for the first data point, thus allowing them to be transferred more quickly. Second offsets can be cascaded off the first offsets for a third data point defined within the model.
