Many mesh streaming algorithms have focused on the transmission order of the polygon data with respect to the current viewpoint. In contrast to the conventional progressive streaming where the resolution of a model changes in the geometry space, we present an new approach which firstly partitions a mesh into several patches, then converts these patch into multi-chart geometry images(MCGIM). After all the MCGIM and normal map atlas are obtained by regular re-sampling, we could construct the regular quadtree-based hierarchical representation based on MCGIM. Experimental results have shown the effectiveness of our approach where one server streams the MCGIM texture atlas to the clients.
