Embodiment Construction

[0031] The following are specific implementation methods of the present invention. The present invention divides the region into two types: update region (Update Region, UR) and order region (Subscribe Region, SR); set the residual error threshold (Dimension Change Threshold, DCT) on the coordinate axis for the numerical residual error of the region, and the coordinate axis Upper residual threshold factor (Dimension ChangeThreshold Factor, DCTF); regional information network packets are divided into regional snapshot information (Region Snapshot Info, RSI), regional difference information (Region Delta Info, RDI), regional heartbeat information (Region HeartBeat Info, RHI), Region Request Info (Region Request Info, RRI) four categories. These three types of messages are used in different occasions, at the same time. The following are explained separately:

[0032] Update Region (UR), which indicates that the interest of the data bound to this region is this region, and all r...

Abstract

A region matching method based on residual displacement error in a distributed virtual environment comprises the following steps: (1) dividing distributed simulation nodes into three kinds of a client node, a partial region manager and a global updating region vindicator; (2) generating residual region error information by the client node; (3) discriminating the residual region information from the client node by the partial region manager; (4) executing matching calculation to the region coverage change information in the received residual region error information by the partial region manager; (5) storing the received residual region error information, a snapshot corresponding to the residual region error information in the snapshot record, the time when the residual region error information is received, and the global region summary information when the residual region error information is applied to the snapshot by the global updating region vindicator with a mode of history record; and (6) transmitting the global region information to the partial region manager by the global updating region vindicator, checking and modifying the partial region information locally stored by the partial region manager according to the global region information. The method according to the invention can effectively and quickly execute region matching for reducing the engagement of bandwidth in network.

Description

technical field [0001] The invention belongs to the field of computer distributed interactive simulation, and in particular relates to an area matching method based on displacement residuals in a distributed virtual environment, which is used for area matching of interest filtering by distributed simulation nodes. Background technique [0002] There are a large number of data exchanges in the distributed virtual interactive environment, which mainly include user joining and exiting, changes of virtual object state information, interaction between virtual objects and so on. The more users and virtual objects participating in virtual interaction, the larger the amount of data the system needs to maintain and exchange. How to accommodate more users and more virtual objects under the existing bandwidth conditions depends on how efficient Distribute object state and interaction data to reduce the network overhead of the entire system. At the same time, with the increase in the n...
