Cultural Relics Restoration Technology in Virtual Reality: Application of 3D Modeling and Rendering Algorithms in Cultural Relics Digitization

Preserving humanity's cultural legacy requires the repair of cultural treasures. Virtual reality (VR), which offers realistic representations and immersive experiences, has become a viable instrument for the restoration of cultural treasures as a result of technological advancements. This research explores the use of sophisticated 3D modelling, rendering, and simplification techniques to digitalize cultural artefacts. The study employs a carefully selected set of 3D models from the publicly available Sketchfab website to examine objects that are representative of cultural heritage, such as the Ashoka Tower, the Tibetan Sacred Props, and the Haihun Marquis Mausoleum. The primary objective is to evaluate how well different rendering algorithms capture and preserve the fine features of these cultural treasures while maximizing computing efficiency. To improve the produced models' visual integrity, the research starts by examining the fundamentals and uses of texture mapping, lighting models, and material attributes. A comparison examination of the original and simplified models is then carried out to assess the trade-offs between rendering time and visual quality in terms of performance. In weighing computing resources against preservation goals, this comparison offers crucial insight on the viability of simplification strategies. The findings highlight how important it is to utilise digital tools to preserve, analyze, and share cultural assets. Through the demonstration of the capabilities of cutting-edge 3D modelling and rendering techniques for capturing and spreading the rich historical and cultural importance embodied by artefacts from many traditions and civilizations, this study adds to the growing area of digital cultural preservation. This study contributes to the continuing conversation about utilising technology in the digital age to protect and promote cultural heritage.
