Design And Implementation Of Interactive 3D Visual Simulation System

With the development of computer network technology and multimedia technology, the inevitable trend of the development of global economy is the digitization has gradually become the focus of concern, the digital virtual simulation more and more people are familiar with, can more waving it in key areas in the irreplaceable role of visual simulation technology is getting more and more interactive control, become a a new study of digital city development. Prediction, in the market to prevent pollution in environment control, in the development of city planning and controled in transportation and so on, "virtual reality" so that people can in a seemingly virtual and close to real environment, can use the man-machine interactive way to simulate roaming full range of strange the environment of the future, make people realize the no actual contact can really feel a strange environment landscape.This paper mainly through the study and research of 3D interactive simulation of some of the more important key technical problems in the unit, the campus scene as the carrier of virtual environment, in the visual simulation system, the design and implementation of the construction of the whole 3D interactive simulation system can stabilize the real time operation. In the process of realizing the system, solve the collision problem between object model and object in the scene, model number in the system real-time optimization problem of interaction, modeling technology of three-dimensional model of how to build the model, and how to create the simulation effect problem of real class environment.In college campus environment as a virtual simulation environment of the research object of this system, in the process of implementation of the system, continuous learning and some key technical problems in the field of visual simulation, on the basis of this, to meet the requirements of the design can be a man-machine interactive 3D visual simulation system, the process is first determine the plan system performance environment, build a virtual reality model using the 3D modeling software 3ds Max and MultiGen Creator to build the 3D virtual scene model environment, and then optimize and crash test on the virtual scene model; at last the design and Realization of the system, the use of Vega in Prime man-machine interactive walkthrough module and man-machine simulation roaming the interactive control of three-dimensional virtual space scene.
