The Garden Of Changbai Mountain Cruise System Based On Virtual Reality Technology

Recently, we enter a new information age along with the development of technology and progress of human beings, and digital technology brings great changes to our lives. Gradually, the computer became to a main tool of data processing and a main channel of exchanging information with the humans .While the newest creating, the problems appears——human-computer interactive interface has been a major obstacle. Especially how to overcome this obstacle for the ones who are not professional, so that they can operate the computer easily and deal with the challenges of Information Age. Which is hot topics of scientific research organizations of computer all over the world.Traditional human-computer interactive interface is based on window, keyboard, mouse, which is called WINP mode. Such interactive mode is indirect, non-intuitive, limited, and this will affect the use of computer, and even affect users' normal work and life. This simple interactive mode is hard to handle large mount of data, so will cause barriers for the human perception the complex dynamic features of things across time and space, the best solution is virtual reality technology.The technology of virtual reality has been divided into two definitions, narrow and board. For narrow, it is considered an advanced human-computer interface, which based on natural. In this environment, all the things and scenes people could see can be considered as a feedback from the virtual scene, which creates a sense of immersive to the users. But for the board, it is a Three-dimensional visualization technology, simulating the real scene into a three dimensional world, reproducing a particular scenario; using this natural way the users can receive and respond to the organ stimulations which coming from the virtual scene. For this, people can have a good communication with the virtual environment, which gives a true and objective feeling.Above all, the virtual reality technology is a kind of technology, based on the computer technology, can generate a realistic virtual environment; using some special equipments, users can interact and influence with all objects from the virtual world, this will give people a true feeling.It is mainly composed by a variety of factors, the computer, input and output devices, applications software and databases. The computer is considered as the core part of creating the virtual scene, which is responsible for generating the virtual environment and achieving human-computer interaction and so on. In the completion of the virtual environment, input and output devices are the main channel for the interaction between human and virtual environment. And some specialized equipments can make the browse results better. Application software is the necessary tools to build the three-dimensional model, natural effects, sound effects and so on. Databases are used to store all the data the entire virtual environment needed.Three features of the virtual reality technology are immersion, interaction and imagination. Immersion, makes users feel full exposure into the virtual system and hard to distinguish between true and false, even beyond the reality, to achieve better brightness and sound effects than the real environment. Interactivity refers to the viewer using a special device to communicate with all objects from the virtual environment and interact each other and can make them feel the excitement and impact. Imagination, which refers to the virtual environment is created by the creator, not the real objective, reflecting the creator's rich imagination, to achieve specific goals. Based on three characteristics, the virtual reality technology has been applied to various fields, such as: military, medical, education, sports. In these areas, the virtual reality technology generates corresponding virtual environments to make good conditions for their development.The purpose of this paper is to study various aspects of virtual reality technology. In this paper, the Virtual Reality Modeling Language (VRML) and X3D modeling language is introduced, and a modeling software - 3DSMAX is also introduced. Finally, we can establish the garden of Changbai mountain cruise system by the research of virtual reality technology.VRML language syntax is simple, most notably is the use of nodes. Every object in the virtual scene is achieved by node, the properties of node determines the object's color, shape and other factors. Also Java and Java Script can be embedded in the node to achieve the design of interactive and dynamic science. Compared to VRML, X3D modeling is more efficient, because it does not need to create the node, but only need to change the attributes of each node domain in the editor. The 3DSMAX is a specialized modeling software, it does not need to write code. By adding pictures of real objects to 3DSMAX software and some particular button, the object can be virtualized. Although it is fast and convenient, for some effects which can not be seen by users, such as: atmospheric effects, sound and other effects, it still need to insert VRML node to achieve. Good understanding of such knowledge is the basic to learn virtual reality technology, through the research of virtual reality technology, I have established the garden of Changbai mountain cruise system, and get a solid foundation to research on the deeper aspects of the virtual reality technology.
