Abstract: Multiple vehicles being simulated at multiple devices are coordinated across a network as part of a shared gaming experience. Participating devices initially synchronize a time base using a designated host device. During game play, local devices simulate local vehicles. Local devices also produce predicted vehicle states for the local vehicles and transmit the predicted vehicle states to remote devices with regard to network latency. Remote devices in turn produce interpolated vehicle states from the predicted vehicles states and then render the vehicles using the interpolated vehicle states. Interpolation values may also be employed to maintain the synchronized time base. Additionally, the interpolations may be tuned, especially with respect to collisions, by a glancing collisions handler, a dragging collisions effectuator, and/or a remote vehicle damage agent.
