## 1 Introduction
### Technological Materials: Recent Improvements
Another example of a game engine being used in museums is Labyrinth 3D. This application, primarily for educational and informational purposes, is based on 3D images of artworks in a museum and the interaction between them [15]. Rome Reborn (1997-2012) is a virtual ancient city built in an international effort involving research groups from the USA and Italy. The project is based on creating a digital model of ancient Rome as it appeared in late antiquity. The main purpose of the project is to spatialize and present theories about how the city looked at this point, which was the culmination of its development as the capital of the Roman Empire. The second purpose is to form a cyber framework where the model can be updated, expanded, and bettered. The Rome Reborn project distinguishes two types of elements in the model. Class I elements (detailed models) are sites that have detailed information about identification, location, and design. Approximately 30 elements fall into this category. Class II (procedural models) are the 6750 buildings and moments (such as single-family houses, apartment buildings, warehouses, etc.) that lack precise information [16; 17]. The ancient city of Palmyra--which is located in Syria--is geographically located close to the city of Antioch. With the help of the project Palmyra, 3D models of Colonnaded Street, the amphitheater, and the Bel and Baalshamin temples have been made. The models were not covered or textured but were instead left monochromatic [18; 19]. Another project in Palmyra presents sketches and information given in diaries, along with archival photos, paintings, inscriptions, and sculptures, in an interactive web-based digital model of a monumental underground tomb, the so-called tomb of [PERSON] [20]. A study on the ruins of the ancient city was also carried out on the city of Karakorum (Mongolia). This project explores the first attempt to virtually rebuild the historic city of Karakorum based on ruins and archaeological findings from the 13 th century AD. Only a group of buildings, called the Great Hall, was 3D modeled, and the platform was created with game engine integration [21]. Research on the virtual reconstruction of the historic city of Al-Zubarah in Qatar consisted of two phases. First, the creation of a volumetric solid model of the city and then the detailing of four important structures: the mosque, palace, towers, and bazaar [22]. [PERSON] et al., (2019) tried to install cultural heritage, 3D modeling, and game engine technologies on a PC system. This article examines the development of a 3D model built from plans of a Roman edifice and its transfer into four game engines as vehicles for independent navigation around the 'virtual building' [23]. As a result, pilot studies are generally done in the form of 3D as modeling of several building blocks for the revival of cultural heritage in literature. Studies in which an ancient city is animated with its topography, landscape, and atmosphere have not been encountered, except for Rome Reborn 2.0. The most distinctive difference of our study is that an ancient city, which has very few ruins, is completely modeled with its topography and loaded into the game engine.
