Underwater Weapon System Simulation Demo

With the development of computer graphics and computer network, computer simulation is demanded to be more intuitionistic, exehengeable and intelligible. Simulation demo technology is to transform information that the simulation has produced to scene, images and processes that are easily acceptable in order to make decisions. This thesis introduces a new type of mathematic simulation for torpedo weapon system, which is one of the key pre-researching projects raised by the National Science and Technology Committee in the ninth five-years. Its primary tasks and distinguishing features can be summarized as follows:(1)With the in-depth research of three-dimensional graphics modeling, the paper investigated the four methods of compartmentation and recombination, the curving surface composition, trigon joint, Oriented-Object technology.(2)Three-dimensional geometrical objects(torpedo, warship, submarine and some other underwater vehicles) are designed by standard OpenGL. The data-driven 3D graph can display the motion of torpedo, warship, submarine according to their motion variables like position, velocity and attitude.(3)Three-dimensional graphics modeling of underwater weapons are completed by 3DSMAX. The document framework and data storage format are analyzed. The problem how 3DS model is used has also been discussed. Thus we can generate more complicated graphics than that are generated by OpenGL.(4)The method is presented which can raise the speed of scene rendering. Under the precondition of limited resources holding, the contradiction between the fidelity of image display and real-time feature of system interaction process is better resolved with the using of Texture Mapping and display list technology. The scene display speed is raised effectively.(5)The functions of graphical animation, voice playing, Human-Computer interaction and viewpoint rambling in the demo system are realized so that the simulating staff may look at circumstances from different viewpoints and positions for the benefit of performance evaluations to underwater weapons.
