Abstract:
A common problem in remote rendering setups, is that of temporarily insufficient bandwidth and latency. For a proper experience of immersiveness, at least some rendering should be presented to the user, and it should appear to be responsive to user input, even in the presence of connection glitches. The all too familiar spinning hourglass symbol, or equivalent, will degrade such an experience. With the advent of VR and AR, solutions to this become important even though connectedness in general is improving. We are dealing with a remote rendering of 3D geometry being pushed to a lesser client, and what we in essence do is to replace a spinning hourglass symbol with an automatically client-generated approximation of the 3D geometry rendered on the client, responding to client-recorded user input. We call this a proxy model. Our main result is a system for automatically producing such proxy models on the client, from received images and depth buffers only, for showing on the client when remotely rendered frames do not arrive sufficiently fast.
