High speed networks which guarantee a minimum quality of service (QoS) enable the development of interactive Web systems. The paper introduces a new paradigm for interaction with complex virtual worlds on the Web, which utilizes both the server and the client simultaneously. The client generates the new views by extrapolating a reference view based on the locally available data, including the model. The server transmits only the data necessary to prevent an accumulation of errors. The model based view extrapolation method avoids the use of textures which are view independent primitives and therefore too expensive to be used in interactive applications over the network.
