基于SketchUp的农产品食品实训基地三维虚拟构建

摘要

ABSTRACT:Objective Virtual reality technology is an emerging technology, and has been widely applied in many areas. The aim of this study was to build three-dimensional (3D) virtual scene of training base by advanced 3D modeling techniques, so as to further improve the geographical information and enrich map display methods for the agricultural food training base. Methods Combined with 3D virtual technology of the digital era, taking the agricultural food training base of Zhejiang Economic and Trade Polytechnic as example, the technical route, the modeling process of 3D models and scenes were discussed based on SketchUp software.Results The new 3D models and scenes combined with some real cases such as building layout, internal space and analytical instruments were created with SketchUp software.Conclusion The results of a series experiments show that the modeling method has the characteristics of easy to learn, powerful operability and process-oriented. It is a very practical 3D geological modeling method and will provide some beneficial reference to the construction of the training base in colleges and universities.%目的：虚拟现实技术是一门新兴技术，在各个领域的应用越来越广。为进一步提高农产品食品实训基地的地理信息量，丰富实训基地的展示手段，拟采用先进的三维建模技术，构建实训基地的三维虚拟场景。方法结合数字化时代的三维虚拟技术，以浙江经贸职业技术学院农产品食品实训基地为研究对象，探讨基于SketchUp软件的实训基地三维模型和场景的构建方法、技术路线和建模流程。结果开发了三维模型和可视化虚拟场景，对实训室总体建筑布局、检测室内部空间和检测仪器设备进行虚拟展示。结论 SketchUp软件可以提供一种多视角的三维虚拟实训室解决方案，具有简单易学，可操作性强和流程化的特点，是一种非常实用的三维建模工具。项目研究可为高校虚拟实训室的建设提供有益的参考和借鉴。
