WEB-based Three-dimensional Virtual University Roaming System Design And Implementation

Born in 3D special effects work more and more today, three-dimensional virtual roaming technology as the most important realistic simulation technology in the field of 3D has been popularized and applied in many familiar industry, such as the coal industry, city marketing, digital product promotion, 3D games, indoor and outdoor decoration design, education etc..After finishing the study on the application and development of China and other developed countries the 3D virtual university system, the Xi’an External affairs Institute system performance as background, to the full range of three-dimensional display of Xi’an External affairs Institute software and hardware construction for the purpose, design based on 3D virtual WEB to the west "roaming roaming system". The main content of this study includes 3D modeling, 3D animation, dynamic interactive operation, the particle system, collision system, multimedia technology, scene sky illumination control system, optimization of key technology of virtual walkthrough.In the specific functions to achieve a three-dimensional model of three-dimensional angle display and real-time roaming operation. Access and the information inquiry and the virtual classroom module export. All 3D roaming system using 3D Studio Max 2010 as the main modeling tool, interactive control through the Virtools4.0 model for merger and consolidation and by the specified program. In the process of modeling the modeling method is fast and effective for terrain features different, largely improves the Maps application technology.The whole system can reach the effect of true, mix the spurious with the genuine, full of the scenery and the learning environment for the show, the school’s landmark buildings were increased by concise text, so that the operator can quickly browse single browsing and online, and stick out a mile.
