Research on the digital design of Han Dynasty pottery granary building based on miniature experience

As an important material cultural heritage of China, pottery granary buildings embody the rich social landscape and cultural significance of the Han Dynasty. Due to the current reliance on static displays or fragmented interpretations, it is difficult to intuitively present the relationship between architectural structures and cultural symbols. This study proposes an immersive “miniature experience” framework for digital reconstruction and interactive display. Based on 84 excavated pottery granary samples, the study systematically extracts planar images, chromatic characteristics, and three-dimensional structures to reconstruct three-dimensional virtual models. Using modular modeling techniques, three-dimensional virtual models are constructed, and virtual characters are designed to explore the interior spaces of the buildings. Usability testing (n = 80) revealed that, compared to traditional static display methods, the miniature experience significantly enhanced engagement (mean=3.55 vs. 2.025) and cultural understanding. This study provides innovative strategies for the multidimensional integration of heritage conservation, cultural heritage, and interactive design.
