The goal of this project is to design and realize a highly interactive and three-dimensional locomotive museum online exhibition hall. With Unreal Engine as the main development platform, the powerful performance effect and blueprint interaction of Unreal Engine are used to create a high-quality online exhibition hall for locomotive culture lovers, so that they can understand and explore locomotive culture more comprehensively. With the continuous development of network technology and virtual reality technology, the form of online exhibition hall has become an important way of exhibition. Many museums, art galleries, science and technology museums and other cultural venues have taken online exhibitions as their important display methods, and actively try various innovative designs and applications in practice. On the one hand, online exhibition halls have the advantage of spanning time and space; on the other hand, online exhibitions can also greatly expand the number and scope of visitors, so that more people have the opportunity to browse the museum's precious collections and exhibits. At the same time, in recent years, with the continuous advancement and popularization of virtual reality (Virtual Reality) and augmented reality (Augmented Reality) technologies, VR museums such as XMuseum have gradually appeared in the public eye. The use of virtual reality technology can create a more colorful way of online exhibition, bringing immersive experience and stronger interaction to the audience.
