Virtual reality design and production practical training and teaching involves VR project design,VR modeling,VR animation,texture image generation,VR engine production,C#programming,VR human-computer in-teraction development,and immersive headset device interaction development.The instructional difficulties make it difficult for students to master.In response to these problems,an immersive and integrated simulation training teaching method is investigated.Based on the study of the actual process of VR project design and production,the sys-tem functional modules and the overall structure of the system are designed,the system development method and de-velopment process are proposed,the HTC VIVE immersive system and C#programming are used to realise the human-computer interaction function,the Red Army climbing snowy mountains is used as the teaching and development case,the model library,code library and resource library are integrated,3DsMAX is used to train VR modeling,VR animation and other content,and using the Unity3D engine and its C#language to train VR human-computer interac-tion development skills,a set of simulation training system integrating various techniques of virtual reality design and production has been developed.Experiments show that the method enables students to be in an immersive environment and train according to the VR project development process.It enhances students'interest and willingness to teach practical training and helps them quickly master the skills of various stages of VR design and production.
