The Design And Implementation Of The Roaming System In3D Virtual Campus

With the development of society, science and technology, based on the image rendering of virtual reality technology has become the computer vision, image processing, computer graphics, artificial intelligence research hot spot. Although the virtual reality technology has been great implicated in many fields in the practical, such as military, medical, and business and other fields, but not involved in the education system, how to help the residual disease people to overcome the existing environment barriers. So the development of3d virtual campus navigation system is necessary.In this paper, the design and development of3d virtual campus roaming system, based on the real campus overall blueprint (campus layout, traffic, landscape design, teaching and living environment), succeeded in virtual reality where part of the campus, the visitor can be automatically roaming, embodies the artistic quality and authenticity of the environment. And on this basis the automatic roaming video recording, let visitors can more intuitive understanding of the campus environment construction. The goal of this article is based on Unity3D technology to produce3Dvirtual campus roaming video automatically. In the whole production process mainly by Maya2013and Unity3d as a development tool, the Maya2013is mainly used in building construction, facilities such as a variety of model making and mapping, topographical environment of Unity3D is used to build schools and roaming animation production; Second, also use Photoshop CS5secondary development, its role is mainly producing and processing model map; Finally, using KKcapture auxiliary roaming video recording and the use of Premiere of those editors late for video editing and special effects, etc. The ultimate goal is to make a3D virtual campus roaming automatically video AD. The main content of this study is the production of virtual campus environment in the Unity3D and roaming animation production. Build virtual environment and involves the terrain height map, topographic map, the planting of trees and the sky box and water use and the scenario model import put; Debugging of the whole environment rendering, make whole scenes show the real world of realistic and stereo feeling, the audience can have immersive feeling. Automatic roaming mainly through the Animation editor to create, through the use of the camera of push, pull, shake, shift, etc way to complete the automatic navigation path Animation. Through above design can realize the complete3d virtual campus navigation system, users can feel the campus scenery more intuitive also can enrich the research of VR technology in the education system provide convenience for the later research. So this work has great practicability and reference value.
