摘要
针对虚拟现实技术在电子商务等领域的广泛应用,阐述了虚拟现实的概念、几种实现方法的原理。给出了用杰图造型师软件实现面向景点的三维全景图和面向物体的三维全景图的方法和步骤;分析了连接www网的场景描述语言—VRML的语言结构,编辑方法和VRML的常用浏览器软件,这样用键盘或鼠标任意改变视角来观看在网页上展示的各种产品。总结了虚拟现实技术未来的应用领域和应用前景,以及受成本、硬件、带宽、模拟环境等因素的影响可以选择不同的技术形式。
This paper introduces the concept of Virtual Reality and the theory of some realizing ways because VR has been applied in electronic commerce system. The ModelBuider soft made by Jietu Software can lay out 3-D scenery of the real scene and 3-D shapes of the real object. A language for describing 3-D shapes and scenery on the World Wide Web —— VRML (the Virtual Reality Modeling Language) is introduced in this paper. We present the structure of language, the editor of VRML and some browsers. Lots of products can be studied in different visual angles through the keys and the mouse in the generated browsing program. We summarize the applicative fields and the applicative prospects of Virtual Reality in the future,different technology can be chosen because of different cost, hardware, bandwidth, simulant condition, etc.
