Abstract: The paper aims at a theoretical analysis on the object modeling and interaction between simulation nodes in distributed visual simulation, and to study the method of implementation of DIS combined with dynamic graphics. For this purpose simulation platform based on LAN is set up, objects of all situations are modelled, entitiy states and interaction information on the network are transfered and the dynamic display of interaction between entities is realized. The dynamic display is based on a DIS platform. The visual simulation based on DIS raises a high demand on the graphics and the net processing ability of the simulation nodes, thus optimization in the modeling and choice of algorithms are required.
