Abstract:With regard to the limitations of traditional chemistry teaching and the deficiencies of existing virtual chemistry classrooms, a virtual chemistry intelligent classroom system based on Unity3D has been designed and implemented. A virtual scene is constructed and imported into the Unity3D engine, and virtual simulation experiments are performed through the C# script and a particle system. For authority allocation in multi-user virtual scenes, the intelligent auxiliary module with authority strategy is designed to assign different ranges of authority to students and provide prompt functions such as text and video. Besides, the system functions are split through the Spring Cloud-based framework, and the system is optimized by Redis. This system is suitable for chemistry teaching in the middle school. It implements highly-simulated virtual experiments with authority control to solve authority problems in virtual scenarios and improve learning efficiency, with high availability, etc.
