Abstract
A method by which a client and a server cooperate to render views of a virtual reality world within which a user of the client navigates. The server sends the client a reference view and a model to use to extrapolate the reference view in response to the user's virtual movement. The client sends the server a record of the user's virtual movement. Both the client and the server perform the model-based extrapolation of the reference view. The server also performs an exact update of the reference view. When the extrapolated reference view deviates too much from the updated reference view, the server sends the client the difference between the extrapolated and updated reference views, so that the client can update its reference view.
