The first part of this thesis introduces the history of virtual reality technology and analyses the composition of VR industry, and also introduces the application of virtual reality technology in several industries. The second part analyzes the development trend of mainstream social media and introduces the characteristics of several virtual reality social applications. The third part introduces the software used in the creation of the project, details the production process, and shows the model at the end. This project builds a very realistic looking room model in virtual reality. During the design process of the project, I used Google Colab and Stable diffusion to generate the conceptual drawings of the room, and then used AutoCAD to draw the floor plan of the room. During the production of the project, I used 3ds MAX for modeling. At last, the model was imported into Unity, movement control and viewpoint control scripts were written, and the project was showed in first-person view.
