## 4 Discussion and Conclusions  
This research is important for revitalizing lost or destroyed cities, buildings, and their surroundings. Open areas such as roads, pavement, agoras, and avenues--as well as buildings--are modeled. Thus, open urban areas can be perceived in 3D and with depth, enabling experts to produce information and opinions more easily. With character modeling and the creation of dramas, we can reanimate cultural heritage by understanding the dimensional sizes and distances of outdoor social and economic life and recreational areas. Furthermore, this is new work in tracking past cities' historical development because it covers various scientific branches (e.g., archeology, landscaping planning, urban planning, and computer-aided animation). Finally, this is a unique project due to its use of various scientific methods and software integration in fields such as remote perception, solid modeling, and animation. The greatest limitation throughout the study was obtaining real data about the area or structure to be visualized and modeled. If we had decided to model structures whose dimensions and sizes were certain, only two or three buildings would have been realized, not the whole of Antioch, thus limiting our view of the city. Another problem lay in the absence of important structures' (excavated) remains and their presence beneath several meters of present-day Antiakya, where excavations at the desired level are not currently feasible. Furthermore, the real-time engine (OGRE 3D) used for this study cannot fully operate at the desired level. Despite models produced throughout the study being transferred into the engine, problems occurred while localizing coatings because the software in which models are created and the coordinating software systems in the engine differ. In addition, the OGRE 3D game engine has been abandoned due to difficulties in use, interface complexity, and, most importantly, problems in the integration of models. After

This game engine is powerful, works across platforms, and is highly user-friendly to both beginners and experts. Unity 3D is a game engine that is advanced and renders real-world graphics without taking much processing power. The integration with the Unity software, high-resolution panoramic images, and 3D model reconstructions is very successful [47]. Challenges to large-scale animation data visualization, including parallel animation data redundancy, huge data size, dynamic user interaction, and portability, are overcome through algorithms specifically designed for preprocessing simulation data and visualization modules optimized using the powerful 3D rendering and interactive game engine Unity 3D. A comparison of this study with various visualization tools and realistic simulations commonly used to visualize large-scale idealized datasets highlights the visualization efficiency, seamless interaction, and lightweight properties of Ancient Antioch. Therefore, foundational research such as this is significant for early results that are rich in visual quality. We can expect constantly improving images for the preservation, analysis, and interpretation of cultural heritage--whether for the ultimate purpose of introduction, education, or research. In particular, this research is important for animating ancient cities. The example used here involved recreating Ancient Antakya's historical past and introducing its culture, particularly through presentations in museums and art galleries. The images and animations from this study are used in the Hatay Archeology Museum (Figure 12). Perhaps the most important output of this study was the use of almost all of the images obtained in the Hatay Archaeology Museum. The visuals and animations of this study
