【摘要】 作为在计算机图形学、机器人科学、机械学和控制论等基础上发展起来的技术，虚拟现实技术旨在建立一种人工环境，人们可以在这种环境中以一种“自然”方式从事驾驶、操作和设计等实时活动。虚拟现实技术可以提供给用户一种真实的感觉，使用户有一种身临其境的感觉。用户作为主角 存在于虚拟环境中，对虚拟环境内的物体的可随意操作并从环境得到及时的反馈。用户在多维信息空间中，依靠自己的感知和认知能力全方位地获取知识，发挥主观能动性，寻求解答，形成新的概念。虚拟现实技术与Java技术的结合增加了虚拟现实技术与用户的交互功能，用户可以通过Java提供的界面，操纵场景中的任何物体，并改变相应的属性(如：位置，角度，颜色等等)。本篇论文阐述了虚拟现实技术应用在售楼系统中，用真实的三维模型来代替原有的静态图片及文字描述，在实践过程中，分析了Javascript，Java类，及Java applet实现功能中的利弊，分别阐述了它们在本系统中的应用，从理论上讲，本课题所研究的虚拟现实技术不只适用于售楼系统的电子商务中，同样可用于军事和演习、医学、教育、娱乐和工程设计等领域。本课题所研究的系统能实现对房地产信息的全面管理，并且满足用户在实际购房中的需要。因此，本系统有其研究和推广的实际价值。更多还原

【Abstract】 As a technology developed on the basis of computer graphics, robotics, mechanics, cybernetics and other sciences, virtual reality technology aims to build an artificial environment where people can perform various real-time activities such as driving, operating and designing in a "natural "way. virtual reality technology can provide "participants " with a feeling of being personally on the scene.As a main actor in the virtual environment,Userscan control any objects in the virtual environment arbitrarily and can get reaction in time.In the hyperspace of the information,he can get acknowledge with their own percipience and cognition ,and ,seek the solutin ,and form the new conception.the association of the virtual reality technology and Java technology intensify the interaction between the users and viryual reality technology .With the interface provided by Java,The user can control any objecs and change the attributes (such as position,angle,color and etc.).this paper formulizes application of the virtual reality technology in the system of the building seilling which uses the real three dimensions models to replace of static picture’s and word’s description.in the process of the practice,the paper analyses the difference between Javascript,Java claa and Java applet,and formulize the their applications in this system. Theoretically, virtual reality technology in this paper is not only restricted in the building selling ,could be widely used in military training & manoeuvre, medicine, education, engineering design and other fields.the system in this paper can realize the general management of the estate information and meet the customers’ needsin purchase procedure .Therefore ,this system is worthful to be studied and extended.更多还原
