Comparing with the conventional method, interactive method is more security and economy to design tall frame structure . in the past, the superstructure was considered as a single element whose bottom was fixed on the foundation . apparently this approximately approach was unsuitable well for the real structure, so the design was insecurity or diseconomy 在以往的常规设计中,将上部框架看成是柱底固定的独立结构进行计算,不考虑上部结构、基础和地基之间的共同作用,与实际结构的受力与变形存在较大差异,使设计出的结构不安全或不经济。
Distributed virtual environment ( dve ) which is a new computer crossing application technology has many application prospects of later years . it can be used in wide fields . the design of virtual reality system uses advanced hardware technologies and software tools to design a reasonable architecture and interactive methods . using dvr technologies in the military simulation, causes the dramatic reform of the simulation's direction and ideas, drives the development of the military simulation 分布式虚拟环境(distributedvirtualenvironments,以下简称dve或dvr)技术是20世纪80年代初期出现并发展起来的一种基于计算机网络和可计算的大规模沉浸式人机交互环境。分布式虚拟现实带来了人机交互的新概念、新方法,使得人机交互的内容更加丰富、形象,方式更加自然。将分布式虚拟现实技术应用于军事仿真演练,引起了军事演练观念和方式的变革,推动了军事仿真演练的发展。
Virtual reality ( vr ) which is a new and rising computer crossing application technology has vast application prospects . lt can be used in very wide fields . the design of virtual reality system is using advanced hardware technology and software tools to design reasonable architecture and interactive method 虚拟现实技术是一种新兴的、极有应用前景的计算机应用交叉技术。虚拟现实系统的设计就是利用各种先进的硬件技术及软件工具,设计出合理的体系结构及交互手段。
