This work takes "the future travel of the fusion of meta-universe and virtual reality" as the core, and relies on the high-fidelity rendering and dynamic interaction capabilities of the unreal engine to create a sci-fi high-speed rail digital model adapted to the meta-universe ecology, and explores the morphological innovation of future transportation in the scene of virtual and real interweaving. In the construction of the scene, the work breaks the limitation of physical space and constructs a trans-dimensional meta-cosmic transportation network: the high-speed rail line not only shuttles between the holographic buildings of the floating virtual city, but also connects the heterogeneous scenes such as spaceports and submarine capsule cities through "space anchor points". The environment along the way presents dynamic light and shadow changes with the line switching-from the neon-streamed virtual Downtown to the stardust-filled space channel, all by the unreal engine real time tracking technology to restore material details and light refraction effect, enhance immersion. The design of the high-speed rail body focuses on "science fiction function and adaptation to the meta-universe": the appearance adopts streamlined bionic body, and the body is covered with color-changeable quantum coating, which can switch visual textures synchronously with the theme of the meta-universe scene; The power system is set to "zero-carbon nuclear fusion electric space curvature-assisted propulsion". The front of the car is equipped with a quantum navigation module, which can match the multi-node coordinates of the meta-universe in real time; in the car, a full holographic interactive cockpit is built-passengers can access the virtual office interface and scene switching instructions through AR glasses, and the seat has a built-in neural sensing system, which can synchronously adjust somatosensory feedback in linkage with the meta-cosmic environment (such as simulating the slight vibration of weightlessness in space and low-altitude gliding). At the technical level, the work gives full play to the advantages of unreal engine: restore the mechanical structure and interior texture of the high-speed rail body through nano-scale polygon modeling, realize dynamic simulation of the high-speed rail driving state (acceleration, orbit change, space transition) with the help of blueprint system, and support VR/AR equipment access-users can "enter" the cockpit through virtual handles for control, or view the real-time interaction between high-speed rail and meta-universe scenes through AR projection in real space, presenting the core concept of "digital transportation reconstructing future travel logic.
