Based On The ViWo Design And Implementation Of Large-scale Complex Scene Editor

Virtual reality system is a simulation technology, computer graphics, man-machine interface technology, sensor technology, network technology, and other disciplines comprehensive technology, data and images can be generated it is similar to the real world of 3d vision, touch, hearing, and other sports, so that people can naturally to experience a virtual world and interaction. Virtual reality system in the simulation, military, aerospace, medical, industrial, entertainment industry, emergency deduction and education has a wide application in related field.Virtual reality 3 d scene is an important part of virtual reality and visual forms, create a real scene can make the human-computer interaction has better immersive experience. To simulate the reality of the danger or difficulty bigger of the real scene, you can use the virtual reality scene is simulated. Simulation of virtual reality 3 d scene to social application has the very high practical value and significance.For large-scale complex scenarios in the virtual reality, different applications need different virtual reality scene, to the same large-scale complex scenarios for different edit and modify, create conform to the requirements of the virtual reality scene. For scenario editor is editor of scene graph, the three dimensional scene graph contains 3 d scenario various logical relationship and attribute information, such as adding the vegetation in the virtual scene model, mobile place building model and related information. According to the specific requirements or real scene to edit operation of virtual scene, is conducive to improve the efficiency of system development, provide users with a create a high degree of freedom and ease of development function of the 3d scene.This paper is to study the existing 3d scene editor technology the way of design, implementation and related theory knowledge, and on the basis of large scale distributed virtual reality system Vi Wo, through the development of large-scale complex system encapsulate the SDK functional modules scenario editor, which make use of the effects of Vi Wo system module, terrain and vector module, combined with the mass data processing, network communication technology and related algorithm optimization technology, implementation of large-scale complicated scene which has the function of creating and editing system tools. This paper studies the main content is as follows:(1) Study and optimization of virtual reality system Vi Wo underlying framework, encapsulation system call interface function of the SDK, increase the scene editing function, can effectively modify scene graph.(2) Large-scale complex scenario editor to edit module and the design and implementation of relevant algorithm.(3) Large-scale complex scenario editor management module design and implementation.(4) Application and effect of large scale complex scene editor in flight simulator system and emergency drilling system.
