Unified event processing method for maintaining time-space consistency in distributed virtual environment

Abstract

The present invention relates to a processing method of the unified event of the time and space consistency in the large-scale distribution type virtual environment based on the wide area network. The method is that the simulation process of the entity object in the distribution virtual environment can be divided in the stages-state calculation, state representation, network transmission, etc. Each event is transmitted to the corresponding calculation node through two steps, that is, the node transmits the event to the unified server first, and the server transmits the event to the opposite node according to the precedence order of arrival of the events. In order to enhance the timeliness, the second network transmission of the previous period of the entity object and the state calculation time of the sequent period are overlapped.

Description

Technical field [0001] The invention relates to a method for maintaining temporal and spatial consistency in a distributed virtual environment, in particular to a unified event processing method for maintaining temporal and spatial consistency in a large-scale distributed virtual environment based on a wide area network. Background technique [0002] Distributed virtual environment is a technical field that studies multi-user network-based distributed interaction, information sharing, and simulated computing virtual environment. The main features are: users interact with virtual environments through interactive devices of computing nodes in different locations; distributed shared virtual environments Local or global data information; computing tasks are distributed to multiple computing nodes to complete collaboratively; the scale of the number of computing nodes and the number of virtual environment entities can be expanded. Its main application areas are: distributed combat sim...

Problems solved by technology

Although there have been about ten years of research on space-time consistency management technology in the world, existing technologies such as local delay, reckoning positioning, delay compensation, time distortion, and object migration are all technical methods to reduce the local impact of space-time inconsistency. It can better maintain the spatio-temporal consistency of small-scale distributed virtual environments, but cannot meet the needs of the new generation of large-scale distributed virtual environments based on wide area networks for spatio-temporal consistency
