1. A method comprising:
- partitioning, via a processor, a three-dimensional wireframe mesh corresponding to a video scene according to (1) a natural object within the three-dimensional wireframe mesh and (2) a motion of the natural object, to yield a first partition comprising the natural object and a second partition;
organizing the first partition and the second partition into respective layers based on a first visual smoothness value for the first partition and a second visual smoothness value associated with the second partition; and
generating one or more bitstreams including the respective layers for transmission.

Abstract
Optimal resilience to errors in packetized streaming 3-D wireframe animation is achieved by partitioning the stream into layers and applying unequal error correction coding to each layer independently to maintain the same overall bitrate. The unequal error protection scheme for each of the layers combined with error concealment at the receiver achieves graceful degradation of streamed animation at higher packet loss rates than approaches that do not account for subjective parameters such as visual smoothness.
