基于X3D构建高效的虚拟场景

Construction of advanced virtual scene based on X3D

随着国民经济和计算机软硬件技术的飞速发展以及人民生活水平的不断提高,虚拟现实技术开始广泛用于社会的各个领域。X3D也已经被定义为可交互操作、可扩展、跨平台的网络3D内容的国际通用标准。真实感、实时性和交互性是虚拟环境的重要特性,结合现有的虚拟现实技术对基于X3D的虚拟场景之开发原理及其开发技术进行了研究,通过实例阐述了虚拟现实应用开发的基本手段和过程,并进一步分析了优化应用的方法,对加快浏览虚拟场景、提高虚拟场景信息的展示效果进行了探索。

With the development and constant improvement of the living standards of the people at full speed of the national economy and software and hardware technology ofthe computer, virtual reality technology begins to be used in each field of the society extensively. X3D has already been defined in order to be can be operated mutually, The sense of reality, real-time character and interaction are important characteristics of the fictitious environment, this article combine existing virtual reality technology to based on X3D fictitious development principle of scene and develop technology go on research, have explained the basic means and course of virtual reality ap- plication and development through the instance, and has analysed further that optimizes the method to use, to accelerating having a look around the fictitious scene, the show result of improving fictitious scene information has been explored.
