## 3 Applications
### Three-Dimensional Scanning Applications in Cultural Heritage Field
This technology was used to scan the Great Wall, providing a precise representation of its current state and allowing for a better understanding of the wall's deterioration over time. This information can be used to provide in-depth data for restoration and conservation efforts, providing an important technological tool in this direction. Figure 7, depicts the relevant 3D scanned model that is publicly available for downloading in \"MyMiniFactory\" online platform [72; 73; 74; 75]. The Sistine Chapel in Vatican City is another documented case where 3D scanning was used to create a detailed digital model of the Sistine Chapel's ceiling fresco, which allowed for the analysis of the painting's technique and the identification of previously unseen details. The Sistine Chapel in Vatican City is one of the most famous and well-preserved works of Renaissance art, and was recently the subject of 3D scanning technology. The 3D scanning process involves capturing detailed digital data of the physical structure and artwork, which can then be used to create a virtual model. This technology was used to scan the Sistine Chapel, providing a precise representation of the artwork and allowing for a better understanding of its preservation over time. This information can be used to inform conservation efforts, helping to ensure that this magnificent work of art will continue to be enjoyed by generations to come. Additionally, the 3D scans provide an opportunity for scholars and researchers to study the artwork in great detail, leading to a deeper understanding of [PERSON]'s techniques and vision [76; 77]. In another documented case, in the Mayan Temples of Tikal, Guatem, 3D scanning was used to create detailed digital models of the Mayan temples of Tikal, which allowed for the analysis of the temples' construction and the identification of previously unseen details. The digital models also allow for virtual exploration of the temples, providing an immersive educational experience for people who may not be able to visit the site in person. The Mayan Temples of Tikal in Guatem are some of the most impressive ancient structures in the Americas, and were recently the subject of 3D scanning technology. Three-dimensional scanning involves capturing detailed digital data of the physical structures,

This technology was used to scan the temples at Tikal, providing a precise representation of their current state and allowing for a better understanding of their history and preservation over time. This information can be used to inform restoration and conservation efforts, helping to ensure that these ancient wonders will continue to stand for generations to come. Additionally, the 3D scans provide an opportunity for scholars and researchers to study the temples in great detail, leading to a deeper understanding of the Mayan civilization and its architectural achievements [78; 79]. In this context, another documented case concerns the Terracotta Army of Xi'an, China, where 3D scanning was used to create detailed digital models of the Terracotta Army, a collection of thousands of life-size terracotta figures that were buried with the first emperor of China. The digital models allow for the analysis of the figures' construction and the identification of previously unseen details. The Terracotta Army of Xi'an in China is one of the most famous collections of ancient sculptures in the world, and was recently the subject of 3D scanning technology. The 3D scanning process involves capturing detailed digital data of the physical sculptures, which can then be used to create a virtual model. This technology was used to scan the Terracotta Army, providing a precise representation of the sculptures and allowing for a better understanding of their preservation over time.
