虚拟仿真

摘要

Newly emerging virtual simulation is the digital simulation of linking VP in the loop. VP can be entity, human and environment in real world, so it can be the production VP, CGF, LRC, virtual battlefield, avatar, soft-man, virtual environment and soon. USA, Japan and England are in the leading position on the field of virtual simu-lation , and China starts a bit late. Application of virtual simulation is very wide. Virtual simulation can estabilish and understand virtual world. The virtual world can be the regeneration of the real world, or can be the imaginary world. Users can interacts to the virtual world using sensors of vision, hearing and touching. Obviously, the virtual simula-tion is in the from of digital simulation.%新兴的虚拟仿真就是仿真回路中接入虚拟样机(VP)的数字仿真.VP可以是真实世界的实体、人体和环境的模型,因此,它可以是产品的VP、计算机生成兵力(CGF)、逻辑靶场概念、虚拟战场、功能化虚拟样机(FVP)、虚拟人、软件人、虚拟环境等等.目前,美国、日本和英国在虚拟仿真方面居于领先地位,我国起步稍晚,但也出现了一些捷足先登者.虚拟仿真的应用,十分广泛.虚拟仿真可创建和体验虚拟世界(Virtual World).此种虚拟世界,可以是现实世界的再现.亦可以是构想中的世界,用户可借助视觉、听觉及触觉等多种传感通道与虚拟世界进行自然的交互.显然,虚拟仿真已把数字仿真置于现代科技发展的高端.
