Research and Design of a Dynamic Forest Growing Simulation System Based on HLA

摘要

In order to address the issues of high coupling of tree shape modeling with communication modeling, as well as limited simulation scale in traditional forest simulation, this paper presents a novel dynamic forest growing simulation system after analyzing the application of High Level Architecture (HLA) and Open Grid Services Architecture (OGSA) technology. In this forest growing simulation system based on HLA, the communication model is constructed by HLA specification and the real-time communication between tree models is carried out by the Run-Time Infrastructure (RTI). The experiments show that the simulation system can avail of all available resources in the grid, and resolve the problem of the simulation results of visual reality and accuracy that can't be satisfied at the same time. Grid services can make the traditional simulation application from single computer distribute to multiple grid nodes. It will improve the speed of virtual scene rendering and the utilization efficiency of grid resources.
