Interactive network-based walkthroughs in large urban environments raise difficult problems due to the size and density of these scenes. Thanks to the strong occlusion complexity of such environments, visibility streaming is a particularly efficient technique for minimizing the network load. In this paper, we present a solution which relies on client-side processing of visibility information so as to minimize the server workload. To solve the problem of transmitting the visibility data to the client, we suggest a bi-level compression scheme for the visibility sets that performs significantly better than previous methods. As a result, the visibility sets can be efficiently transmitted on-demand to the client and then used for adaptive streaming and rendering. Finally, we present our experimental results for a virtual city walkthrough. [ABSTRACT FROM AUTHOR] |
