Research And Realization Of Interactive Virtual Indoor Environment Based On Network

Virtual Reality is one kind of popular advanced human-computer interface technology in recent years and virtual indoor environment technology is obtaining rapid development and recognition as a branch of virtual reality.Along with Internet promotion and popularization, cyberization of virtual indoor environment technology is becoming a kind of tendency gradually and it makes each link of virtual reality obtain circulation and integration on the digital foundation in order that it realizes resources sharing in different place, makes cyberization manufacture possible, reduces time of product development and enhanced the competitive power of product.The paper proposed the design goal "research and realization of interactive virtual indoor environment based on network" under this background and its main content and method is: it constructs a design system of virtual indoor environment based on the Browser/Server structure through software.When the user of the browser sets the request of virtual network design through the Internet at the server, the server carries on the confirmation to the user's status and provides the corresponding information from the database according to the data of the user.If the information is incomplete, It will carry on the supplement according to the custom-made modeling system of virtual reality from the server and transmit the information calculated to the browser through the Internet at last, then the user might watch the virtual indoor environment designed by himself and roam on the browser.The research result of the paper mainly includes:(1) It sets up a virtual network system based on the Browser/Server structure on the single computer by VMware Workstation of the virtual machine software, verifies the structure relationin in the small network with the experimental form of route, net bridge and builds the good design platform for the implementation of design system about virtual indoor environment.(2) It unifies ASP with Dreamweaver MX 2004 to develop the dynamic website on the server of virtual network, unifies Microsoft Access 2003 with Microsoft SQL Server 2000 to set up a database of family housing necessities and provides the technical support of the exhaustive data in the backstage in order that users can visit more resources through database or supplement the recent information for it.This realizes the dynamic exchange visit between users and the website.(3) It unifies the JavaScript script with the VRML language to carry on the programming and carries on the computer aided design with the software of VC++, AutoCAD and its second exploiation tool ObjectARX in order to complete the part of design about virtualindoor environment together.After the user's inputting corresponding parameter, he may roam and observe the effect in the virtual indoor environment designed by himself and may modify parameter manually until he satisfies.The theory and the practical significance of the paper mainly display on:(1) With the help of Internet characteristic, it may concentrate the outstanding design resources in the world, reduce the cost of design and promote management of design to an altitude scientifically.(2) As one kind of interactive three dimensional multimedia modeling language based on network, VRML only needs to transmit viewer's position on network which it saves the data bandwidth and has the huge network superiority.VRML has good compatibility with JavaScript and Html which provides enormous convenient for the interactive virtual design.(3) VMware Workstation is the famous virtual machine software which it may set up a virtual network on the single computer in order to realize many networks amateurs' dream and provide the best experimental platform for these network topics without enough hardware facility.Owing network, the major idea of virtual roaming in different place has realized. Relying on the network which VMware Workstation constructs, strongger Dreamweaver MX 2004 may show its ability, unify ASP to develop the dynamic website and visit database with Microsoft SQL Server 2000 in order to cause this network more complete and real.According to the document and the former design, the topic of developing virtual indoor environment with the software of VRML, JavaScript, Dreamweaver, SQL Server, VMware Workstation, AutoCAD and VC++ has not appeared and virtual network is a tendency in future, so the research content of the paper have extremely positive and profound significance.
