Design and Implementation of Real-Time 3d Interactive System Based on Unreal Engine

In recent years, due to the epidemic and the rapid development of information technology, the experience project combining virtual reality technology and tourism has attracted more and more attention and love. This project attempts to make innovations on the basis of ordinary immersive experience projects to enhance the real-time interaction of experience. Therefore, this project uses virtual reality technology to build a 3D real-time interactive virtual botanical garden system based on virtual engine 4. Based on the theory of virtual reality compensation, the system has realized the integration of the real world and the digital world. On the basis of realizing the immersive tour in the botanical Garden, the project used UE4's Blueprint visual programming to realize the digital experience of dialogue and answering questions, virtual planting, teleportation and so on. At the same time, compared with traditional roaming projects, this system paid more attention to the presentation of themes, and revealed the theme of caring for plants and protecting the environment through Sequence animation. After the test, the scene roaming and various interactive functions in the system are normal, and finally packaged and released.
