Abstract
A progressive coding method and apparatus of three-dimensional (3D) mesh data is provided. The method includes the steps of (a) constructing a 3D triangle mesh of one or more mesh object layers, (b) partitioning each mesh object layer into a plurality of mesh components, (c) forming bitstreams in units of mesh components and coding the same, and (d) combining the coded mesh components into compressed bitstreams and transmitting the same. Therefore, progressive 3D mesh restoration is allowed, and the entropy coding efficiency can be enhanced.
