A Packetization Method for Compressed 3D Model with Virtual Segmentation and Adaptive Graph Coloring

Different from the wired network, the wireless network usually has a high loss ratio caused by the temporary link outage or fading-induced bit error. In order to ensure the 3D model robust transmission, this paper proposed a packetization method for the compressed 3D model based on the interleaving tactics. In this packetization method, we firstly adopt the valence-driven method to visit the full mesh and give each vertex a global index. Then, the presented virtual segmentation divided the full model into several segments. Thirdly, we adopt the presented adaptive graph coloring algorithm to traversal each segment and divide each segment into several packets. Finally, we fetch packets from different segments with a given order and form them into a packets sent sequence. Experimental results demonstrate that the proposed method make the vertices among the consecutive sent packets appeared in the model, which cause the dropped vertices can be reconstructed successfully from the neighboring existed vertices.
