Abstract
A space-time level of detail coder converts a time dependent geometry stream into a hierarchical structure, including levels of detail in the space and time dimensions, and expansion records. The expansion records specify how to reconstruct a mesh from deltas representing differences between levels of detail. For low bandwidth transmission, only selected expansion records need be sent depending on the appropriate level of detail of the object being represented for the current time sample.
