The lecture focused on the idea that 3D visualization in the field of urbanization is not only a means of creating spectacular images, but primarily a tool for analysis, verification of scenarios for the development of territories and communication of complex spatial solutions for different audiences — from planners and architects to investors, community representatives, and future users of space. Volodymyr NAZARENKO drew attention to the fact that the modern city is increasingly considered as a multi-level system, in which digital models help to better understand the relationships between buildings, transport, green areas, public spaces,, and infrastructure.

A separate block of the lecture was devoted to spatial thinking and perspective as a basis for working with architectural, urban and digital environments. The lecturer emphasized that, in the context of urban design, perspective is not only an artistic or graphic technique but also a way to manage attention, explain spatial logic, shape the user experience, and present the future environment in a more human-readable format.

During the lecture, considerable attention was paid to the modern digital workflow - from the initial data to the finished interactive model. Students were shown how GIS, open map data, photogrammetry, LiDAR, CAD/BIM models, modeling and rendering tools, as well as web publishing and presentation environments, are combined into a single chain. SketchUp, Blender, Twinmotion, Unreal Engine, Esri CityEngine, CesiumJS, RealityCapture, and Agisoft Metashape were considered as examples of software tools. This approach enabled students to see that urban design today is impossible without a combination of classical project thinking and digital technologies for analysis and visualization.

The lecture also presented international cases that especially clearly demonstrate the practical value of 3D modeling for urbanization. Among them are Singapore's digital twin as an example of the integrated use of 3D data for city management, Helsinki's open 3D data as an example of an accessible urban information platform, and Rome Reborn, a large-scale project for the digital reconstruction of historic Rome that combines cultural heritage, archaeology, and modern imaging technologies. Based on these examples, it has been shown that 3D urban models can be used both for analytics and planning for future changes, as well as for the reconstruction of lost historical environments, educational purposes and public communication.

An important part of the lecture was a block on the principles of urban design and the modern requirements for future specialists in planning of urban spaces. Single-point, two-point, three-point, isometric, and forced perspective were considered, and how these approaches affect the perception of scale, depth, and movement in space were shown. Volodymyr Nazarenko focused on the fact that high-quality urban design works not only with the form of construction, but primarily with how people move, stop, interact and perceive space. The issues of spatial organization, coherence, functionality, the role of public spaces, streets, squares, courtyards, parks, and mixed zones were considered. The importance of involving the community in discussions of urban projects, as well as the potential of design thinking and gamification to better understand residents' needs and test options for future solutions, was emphasized.

Concluding the lecture, the lecturer drew attention to the interdisciplinary nature of urban studies and urban design and urbanization should combine technical skills, knowledge of spatial planning, the ability to work with visualization and digital models, and. It was emphasized that a specialist in, an understanding of the social, environmental, and cultural aspects of city development. The open lecture aroused the interest of the audience, became a platform for professional discussion of topical topics of urbanization and once again demonstrated the importance of introducing modern digital approaches into the educational process of the Faculty of Information Technologies.

During the discussion, special attention was paid to the role of open urban data, digital twins, interactive web scenes and visualization for public consultations. It was emphasized that it is important for a modern urbanist not only to create a model or render, but also to be able to explain to different audiences how exactly the proposed solutions affect people's daily lives, transport accessibility, environmental comfort and quality of urban spaces.

The participants in the lecture also became acquainted with the possibilities for further practical work on this topic - from mini-projects on modeling urban blocks and public spaces to the use of digital tools in research and qualification work. This format of an open lecture has become an important example of a combination of modern educational approaches, international practices, and applied student training to solve real problems in urbanization, reconstruction, and spatial development.
