The aim was to develop a virtual reality (VR) simulator to help educate greenhouse farmers and consultants. In this second paper a VR simulator that visualises the aerodynamic environment inside greenhouses was developed using VR technology. The three-dimensional greenhouse simulated was designed following the computational fluid dynamics (CFD) computed cases of Kim et al. (reference required). Specifically, the three-dimensional tomato crop models used were created using a three-dimensional scanner. The virtual space was constructed based on the real image models of the greenhouses and the tomato crops. To visualise the aerodynamic environment in the virtual space, a C language-based code was developed to extract the CFD-computed results. Visualisation of the aerodynamic environment was performed using contour plots, two-dimensional vector flows, and three-dimensional vector flows. Contour plots visualised the air temperature and relative humidity through the colours on the active plane. Two-dimensional vector flows represented two-dimensional flows on the active plane. From streamline data, three-dimensional vector flows were developed to represent the overall airflow of the greenhouse. A tablet-shaped user interface (UI) was created so that the user can directly select the desired cases to display. A set of surveys were conducted using random users to optimise the developed VR simulator. From the results of surveys, the final VR simulator to educate the aerodynamic environment in the greenhouse was developed. It is intended to disseminate the VR simulator to various organisations such as educational institutions, research centres, and consulting companies.

目的是开发一个虚拟现实（VR）模拟器，以帮助教育温室农民和顾问。在第二篇论文中，使用VR技术开发了可视化温室内部空气动力学环境的VR模拟器。根据Kim等人的计算流体动力学（CFD）计算案例设计了三维温室模拟程序。（需要参考）。具体而言，使用的三维番茄作物模型是使用三维扫描仪创建的。虚拟空间是根据温室和番茄作物的真实图像模型构建的。为了可视化虚拟空间中的空气动力学环境，开发了基于C语言的代码以提取CFD计算结果。使用等高线图，二维矢量流，和三维矢量流。等高线图通过活动平面上的颜色可视化了空气温度和相对湿度。二维矢量流表示活动平面上的二维流。根据流线数据，开发了三维矢量流来代表温室的整体气流。创建了平板电脑形的用户界面（UI），以便用户可以直接选择要显示的案件。使用随机用户进行了一系列调查，以优化已开发的VR模拟器。根据调查结果，开发了用于教育温室中空气动力学环境的最终VR模拟器。旨在将VR模拟器传播给各种组织，例如教育机构，研究中心和咨询公司。
