【Abstract】 Virtual reality is a result of computer development; it may create some scenery that includes senses of sight, hearing and touch. Its characteristics are multi-sensation, existent sense, interaction and independence. The article mainly introduces model building of dynamic environment, creating timing three-dimensional graph, tridimensional display, sensor, tools of applied system and system integration. It is applied in many fields such as military affairs, medicine, engineer and entertainment. Some developed countries, such as America and Japan, have researched widely, obtaining more grave achievements. Some achievements have also been made in China.更多还原
