【摘要】：随着国内外计算机应用技术的发展,三维虚拟现实技术开始从军事领域普及到教育、医疗、房产、工业、家庭等领域广泛应用,让不同层次人群都能感受到虚拟世界带来的震撼效果。自从2010年在中国上海举办世博会开始,网上的三维虚拟展馆展示技术,越来越多的被一些企业和房产商认可,为了更好的招商引资和宣传推广企业的产品和楼盘,开始有原有的平面产品简介和效果图展示,改为三维虚拟技术展示,也为三维虚拟展示市场带来更广阔的发展空间。目前国内很多制作三维虚拟现实的公司开始针对房地产或园林规划等领域进行项目研发,但是都是一些小型的三维虚拟场景的实现,在一些大型的三维虚拟展示中还存在很多问题,比如：模型的精细化程度、Quest3D模型导入与发布、硬件平台的支持等,因此本课题以中汽零部件苏州产业基地的三维虚拟现实系统设计为例,针对大型三维虚拟现实中存在的问题进行分析解决,首先了解如何规划2000亩的产业园交互式的漫游展示系统方案,并在方案中体现出路径游览、自由浏览、室内外快速切换展示,让观看者能够快速欣赏未来建设好的产业园环境规划布局,从而拓宽国内建筑行业三维虚拟现实的方案设计以及对大型项目的需求分析研究。其次通过对国内外相关三维虚拟现实中场景、材质、交互控制等制作方法进行分析的基础上,对整个大型三维虚拟现实中的场景模型制作方法、烘焙贴图的技术要点、3dsmax与Quest3D模型格式转换、Quest3D摄像机检测碰撞以及如何优化大型场景交互技术等问题进行研究。按项目流程分析主要解决以下问题： 1、了解目前计算机虚拟现实技术在建筑行业的应用领域应用,分析国内外虚拟现实软件研发及优缺点,提出针对于本项目应该使用的虚拟现实软件和硬件分析,并对面临的问题提出方法。 2、分析中汽零部件苏州产业基地的三维虚拟现实系统项目介绍及设计方案,重点解决如何实现2000亩三维展示效果及使用价值。 3、分析使用3dsmax软件对苏州产业园的室外景观进行三维模型创建方法,通过解决建模中简模和精细贴图的有机结合,实现高效的三维模型效果。 4、分析了贴图制作和烘焙技术并制订了相关的规范流程,以确保将模型和贴图完好无损的导入到Quest3D软件中进行调整,实现了优化场景效果。 5、解决了如何将3dsmax制作好的模型进行格式转换到Quest3D软件中,并能够进行快速的修改编辑。 6、解决了Quest3D软件中摄像机的相关参数,重点对摄像机碰撞检测、多个摄像机镜头切换、摄像机沿路径行走等问题,实现观看者多角度、自由互动的了解产业园场景。 7、解决Quest3D中视频嵌套和三维虚拟交互相结合的效果。 8、制作大型三维虚拟现实系统遇到的问题和解决方法及以后的发展方向。
[Abstract]:With the development of computer application technology at home and abroad, 3D virtual reality technology has been widely used from military field to education, medical treatment, real estate, industry, family and so on. Since 2010, when the Expo was held in Shanghai, China, the 3D virtual pavilion display technology has been increasingly recognized by some enterprises and real estate companies. In order to better attract investment and promote the products and properties of enterprises, there are original plane product profiles and effect drawings, which are changed into 3D virtual technology display, and also bring broader development space for 3D virtual display market. At present, many domestic companies that produce 3D virtual reality begin to carry out project research and development for real estate or garden planning and other fields, but all are the realization of some small 3D virtual scene. In some large-scale 3D virtual display, there are still many problems, such as the refinement of the model, Quest 3D model import and release, hardware platform support, etc. Therefore, taking the design of 3D virtual reality system in Suzhou Industrial Base of China Auto parts as an example, the problems existing in large-scale 3D virtual reality are analyzed and solved. First of all, learn how to plan an interactive roaming display system for the 2000 mu industrial park, and show the path tour, free browsing, quick indoor and outdoor display, So that viewers can quickly appreciate the future construction of industrial park environmental planning layout, In order to broaden the domestic construction industry three-dimensional virtual reality scheme design and large-scale project needs analysis. Secondly, through the domestic and foreign related three-dimensional virtual reality scene, material, interactive control and other production methods based on the analysis. In this paper, the methods of making scene model in the whole large-scale 3D virtual reality, the technical essentials of baking map, 3dsmax and Quest3D model format conversion, the collision detection of Quest 3D camera and how to optimize the interaction technology of large-scale scene are studied. According to the project process analysis, the following problems are solved:. 1. To understand the application of computer virtual reality technology in the field of construction industry, analyze the research and development of virtual reality software at home and abroad, and put forward the analysis of virtual reality software and hardware which should be used in this project. And put forward the method to face the problem. 2. This paper analyzes the introduction and design scheme of the 3D virtual reality system in the Suzhou Industrial Base of China Auto parts, and puts emphasis on how to realize the 3D display effect of 2000 mu and its use value. 3. The 3D modeling method for the outdoor landscape of Suzhou Industrial Park is analyzed by using 3dsmax software. By solving the organic combination of simple mold and fine mapping in modeling, an efficient 3D model effect is realized. 4. The mapping and baking techniques are analyzed and the related specification flow is worked out to ensure that the model and map can be imported into Quest3D software to adjust and optimize the scene effect. 5. It solves how to transform the model made by 3dsmax into Quest3D software, and can modify and edit it quickly. 6. The related parameters of the camera in Quest3D software are solved, which focus on camera collision detection, camera lens switching, camera walking along the path and so on, so that the viewer can understand the scene of industry park freely and interactively from different angles. 7. Solving the effect of video nesting and 3D virtual interaction in Quest3D. 8. The problems and solutions of making large-scale three-dimensional virtual reality system and the future development direction.
