The simulation frame based on the photoelectricity scene system of HLA is introduced, using the technology of VEGA scene simulation to design and exploit the photoelectricity scene, and aiming at some pivotal technology in the scene simulation such as the control of model motion and granule system motion, the correlative solutions are given. And then, the two simulation circulate mechanism, HLA and Vega, are coalesced together to obtain the integrated simulation process.
