|
摘要
利用计算机虚拟现实技术,仿真设计unity3D核环境的HPGe γ能谱仪操作平台。该操作平台利用3ds Max软件以稀疏编码模型为理论依据进行建模和渲染,采用SQL Server进行实验数据的存取,在Unity3D引擎中进行资源整合,使用户通过人机交互方式进行实验操作,以此实现对实验过程的仿真及实验结果的展示。实验结果表明:该操作平台能够完整地模拟HPGe γ谱仪操作过程,可应用于操作培训及实验教学。
The HPGe γ spectrometer operating platform was designed by the virtual reality technology,supported by the simulation of real experimental environment in unity3D. It used 3ds Max to model and render,using sparse coding as the theoretical basis. The experimental data were made available to SQL Server. After the integration of models built above in Unity3D engine,user can do an experiment with the human-computer interaction to reconstruct the experimental process. The experimental results show that the operating platform could completely simulate HPGe γ spectrometer operating process. It could be applied to training and experimental teaching.
