Abstract
A computing-device implemented method for compressing data, 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 according to a data collection, each element within the collection having a first data size. A distance is determined between a reference point in the model, and a bounding box for an object. A data reduction factor is selected based, at least in part, on the distance. The data collection is compressed according to the distance by mapping each data of the first data size to data having a second data size smaller than the first data size. Other compression methods and apparatus are disclosed.
