Virtual reality technology is constantly developing, dedicated to computer graphics and multimedia information processing, high-performance chip can increase a hundred times the processing power, three-dimensional graphics algorithms and parametric modeling algorithm enables virtual reality technology is more mature. This paper, the application of virtual reality technology in civil engineering were studied, the results from the demonstration and validation, planning and design, engineering, construction technology and engineering safety management are discussed in this paper. Introduction With the steady growth of China's economy and infrastructure added scale, the scale of construction projects is growing, increasingly complex structure, scientific management of civil engineering, precision increasingly demanding. Realization of civil engineering, information technology, intelligence, visualization and integration become civil construction project management demands of modernization and research focus in this field [1]. Virtual Reality (Virtual Reality, VR) is a comprehensive and highly integrated high-tech, in many areas the military, medicine, design, art, entertainment and other fields have been widely used. Civil Engineering Virtual reality technology in various disciplines involved in civil engineering, has demonstrated some practical, technical potential is huge, very broad application prospects [2-3]. In civil engineering, a long time people had to use abstract concepts represent very rich content, such as using plans, sections, elevations, floor plan and other provisions the formation of some symbols to represent the three dimensional architecture, with more abstract graphics and concise The language used to describe complex scenarios to deliver a lot of information. But this kind of information processing and delivery methods affected employment, knowledge and understanding of the structure of the recipients are engaged in information, communication is very difficult. VR technology development for us to overcome this difficulty provides an extremely effective means. Virtual reality both represent the real world, it can also represent a virtual world. Virtual Reality Technology Overview Virtual reality (VR) a blend of digital image processing, computer graphics, multimedia technology, sensor technology and other information technology branch, greatly promoted the development of computer technology. VR technology is abstract, complex computer data space into an intuitive, user-familiar things. Its essence is to provide an advanced technology of man-machine interface. It is in an analog mode for the user to create a real-time interaction with physical objects reflect changes in the three-dimensional image of the world, in lifelike experience vision, hearing, touch, smell and other acts of perception, so that the participants can directly participate and explore virtual objects and changes in the role of the environment, like being in the real world [4-5]. The architecture is shown in figure 1. International Conference on Materials Engineering and Information Technology Applications (MEITA 2015) © 2015. The authors Published by Atlantis Press 1014 Figure 1.Generic virtual reality software systems architecture Virtual reality technology has the characteristics of the following three aspects. Is sex. Virtual reality technology is based on human vision, hearing the physiological and psychological characteristics, lifelike three-dimensional image generated by the computer, users wear the helmet mounted display and data gloves and other interactive devices, and can be yourself in a virtual environment, become a member of the virtual environment. The user interaction with various objects in the virtual environment, like in the real world, all feeling is so real, have a feeling of intimacy. Interactivity. Human-computer interaction in virtual reality system is a kind of close to natural interaction, users not only can use the computer keyboard, mouse to interact, but also through the special helmet, such as data glove sensing devices to interact. Users through their natural skills such as language, body movement or action, can for inspection or operation of objects in the virtual environment. More perceptual. Due to see, hear, touch, are installed in the virtual reality system, and kinesthetic The virtual reality on civil engineering design based on 3D modeling Virtual reality on civil engineering based on 3D modeling technology using geometric design, geometric virtual reality technology, is through the 3D and 3D object model scene, usually with the help of a professional modeling software (3ds Max, Maya, etc.) to complete civil engineering design approach that more practical performance scenes and objects in the real world [6], but also to create animations. The effect of virtual reality display rich, powerful, and the interactive is strong.
