Research And Implementation Of Naval Complex Model Action Controlling Visual Simulation

Military Simulation Technology has been paid more attention and applied extensively as one practical subject, which has unique advantage as more effective , lower costly and less risk. In order to realize the computer-aided research of new-type weapon, evaluate the effects on decision-making and reduce military spending, people has developed many simulation systems in the field of virtue joint maneuver and weapon simulation.Naval complex, including naval vessel, artilleries and missiles is a kind of all-round defensive system of weapons. This work, having the background of a real project as well as the features of simulation technology, will analyze and apply the naval complex simulation to virtue marine environment. Based on analyzing a multitude of main technologies of simulations and Kinetics knowledge, the research will design and realize the trajectories of the missile and shell with which it will also simulate and process the action of models in the scene. Besides, this research will also propose one Incremental method for the coordinates of trajectory calculation. Then enhancing Intersection Vector Technology, the study will improve the conventional Octree collision detection algorithm. It is also going to establish a structure of weapon simulation system as well as raise one real-time data processing method in the system. The main research of this work is also as following:At first, it will study a myriad of basic points of the simulation system, maintaining the establishing of coordinate systems in the scene, the transformation of Homogeneous coordination as well as the Model optimization Technology. Secondly, particle effects technolog and collision detection methods are to be analyzed and applied, and the conventional Octree collision detection algorithm of Intersection Vector Technology is also going to be improved. Thirdly, the work will model the trajectories of the missile and shell, fit the trajectories of shells with Hermite Curve Interpolation Method, and practice the missile path using Bezier cubic approximation technique based on the foundation of kinetics. In addition, according to the discretization and real-time characteristics of simulation system, the work raises one Incremental method the coordinates of trajectory calculation. Moreover, it will simulate the virtue marine environment, and research the method of naval vessel's actions simulation in such atmosphere, design the Warship-guns rotation's Kinetics model as well as put the pop-up process of artillery into practice. Finally, the work will establish a frame of weapon simulation system, and propose one real-time data processing method in this system in the light of the real-time characteristic and the time stamp algorithms.
