Based On Osg Marine Environment Modeling And Simulation Technology Research

Virtual reality technology is a new comprehensive integration of information technology,involving computer graphics, human-computer interaction technology, artificial intelligence,sensor technology and other disciplines, which combines results of the latest developments invarious disciplines, and applied to a wide range of social production and life in various fields.In recent years, large-scale ocean scenes draws more and more the concern of workers invarious related fields. In the aspect of production and normal life, marine scene has become themain assistive technology in computer game design, film special effects production, marineengineering and other aspects; in the aspect of military defense, marine scene simulation hasbecome a necessary technicalf for national naval in tactical exercises of the combatants, basicsubjects essential training and military deployment.China’s marine area is vast, ocean technologyin the national economy and national security occupies a pivotal position, but also the marineenvironment in the virtual reality simulation is a hot topic of research. To achieve realistic virtualreality scene ocean, covering a wide range of technology areas, such as large-scale ocean scenerendering, sea, waves of cash and scenes organizations. Ocean scenes of virtual reality technologyto achieve can be divided into modeling and rendering ocean scenes of two main parts, first have agood ocean scene modeling methodology to ensure the authenticity of the draw ocean scenes andreal-time, then re-use simple drawing process algorithm.This paper first to make use of virtual reality system and development platform graphicsdevelopment library to parse and build; followed in the study of existing marine scene modelingalgorithm used in this article based on the base unit based Genster wave, using fast Fouriertransform, combined with the waves spectrum of waves modeling algorithm; and then toenhance the authenticity of ocean scenes, the use of OpenScenceGraph graphics library builtparticle system, the scene of marine weather, moderate rain, snow and other particle effects.Finally, the effects of this experiment show that the proposed algorithm and draw the particlesystem in real time on the authenticity and have achieved satisfactory results...
