Abstract: Preserving documentary legacy is crucial for promoting cultural values, education, and societal growth. However, challenges such as environmental factors, financial concerns, and legal requirements necessitate proper preservation strategies. Advancements in 3D modeling and digital technologies have revolutionized the study and preservation of historical architecture, enhancing understanding and communication. Rendering engines and immersive technologies play a crucial role in 3D modeling and visualization, empowering artists to enhance visual quality and engagement. The Turin 1911 project focuses on digitally reconstructing historical buildings, addressing limitations to achieve a faithful representation. The Pavilion of Hungary serves as a notable case study, showcasing comprehensive approaches to creating accurate 2D representations and subsequent 3D models.
