Abstract: NAVL (Newtonian Architecture for Virtual Landscapes) is a distributed virtual reality system designed with the goal of achieving a high degree of network efficiency; in particular, by: - using a hierarchical network architecture that is more efficient than traditional peer-to-peer or client/server architectures, and - simulating the virtual world on the local hosts using a Newtonian based model, thereby functioning as a high order dead reckoning protocol. This paper presents the general overview of the NAVL VR system along with details of the proposed implementation.
