Research on the Construction of Virtual Reality Simulation System of Cultural Heritage Based on 3D Dynamic View

This paper aims to build a virtual reality simulation system of cultural heritage based on 3D dynamic view, using advanced 3D modeling technology, dynamic view rendering algorithm and interactive design to improve the virtual presentation quality and user experience of cultural heritage. First, the cultural heritage is accurately 3D modeled by laser scanning and photogrammetry technology to obtain high-quality point cloud data. After noise processing and data fusion, a 3D model with rich details is generated. Then, the dynamic view rendering algorithm is applied to provide realistic scene rendering effects by simulating physical properties such as lighting, shadows, and reflections, so that users can have an immersive experience in the virtual environment. In terms of interactive design, combined with VR controller and gesture recognition technology, users can freely browse the cultural heritage model, view details and interact with the scene. In addition, this paper also conducted experimental verification, using the Unity platform to build a simulation environment, and conducted virtual display and user testing of multiple cultural heritage scenes. The experimental results show that the system can reconstruct the cultural heritage model with an accuracy of more than 95 %, the rendering frame rate is stable at more than 60 frames per second, the light and shadow effects are realistic, and the user experience is highly evaluated. By comparing different algorithms, the system is superior to traditional methods in terms of accuracy, rendering effect and interactive performance, and has high practical application value.
