Defeating lag in network-distributed physics simulations: an architecture supporting declarative network physics representation protocols

Abstract

Current shared worlds for games, simulations, AR, and VR rely on "good-enough" intuitively correct depictions of shared world state. This is inadequate to provide repeatable, verifiable results for decision-making, safety related/equipment-in-the-loop simulations, or distributed multi-user augmented reality. These require world representations which are physically correct to a designer-defined level of fidelity and produce repeatable, verifiable results. A network-distributed dynamic simulation architecture as illustrated in Figure 1 is presented, with consistent distributed state and selective level of physics-based fidelity with known bounds on transient durations when state diverges due to external input. Coherent dynamic state has previously been considered impossible.
