The Real-Time Image Formation In3D Simulation And Distributed System Research

Nowadays3d simulation technology is applied more and more,and widely used incivil and military, therefore, normal3d simulation system requires that date of scene,scene operation and presentation are all in the same machine, as a result of that adistributed system is required in the cooperation between different departments,3dsimulation system with a distributed part is the trend of the software development.Real-time simulation and acquisition, can be done between multiple terminal，exchanging data between the workstations, using the data of the transmission, it canstructure the whole3-d scene, and also can be used to guarantee the entitysynchronization in distributed system, in the realizing of the distanced modified3dsimulation system and the real-time operation.This Thesis introduced the real-time image simulation, that can the architecture ofdistributed structure, through the optical fiber network communications or laser memorycard, to send the organization data scene between terminals sets, organization andmodification can be done right at the same time of the simulation. In order to ensure itshigh reaction capability in the Windows system, specially designed multiple CPUmonopoly, and others technology such as multi-thread technical to raise up thesimulation frame rate, to get real-time simulation results, according to the count of thescene, the rate of the simulation can reach3000frames per second high in experiments.At the same time, I also done a lot of research on how to improve the degree of reality insimulation, to make the simulation of the maximum effect.After completing the distributed real-time formation, according to the needs,I alsoadded the image collection function, had guaranteed in not impact to the simulation rate,and recorded the simulation results. In this Thesis, I have solved the real-time imageformation, and also found the limitation in real time acquisition, to the features, anddesigned the large image (maximum pixel can reach14000x14000), which is the beyondscreen resolution image collection. At last, in order to ensure that3d simulation of the system of distribution, wecompleted a distributed communication function module design and implementation,according to the needs of the project, designed communication interactive module andsynchronization module. This Thesis used the server/client message communicationmode to feed the requirement of time synchronization and the entity synchronization indistributed system. The Thesis almost finished a complete distributed solution in3dsimulation entity synchronization, time synchronization, which can be independent of thearchitecture of the ground floor of a distributed system frame module.
