Abstract: The article is devoted to the virtual reconstruction of small architectural forms of the Bogoroditsky Park of the Bobrinsky estate. In addition to the unique architectural ensemble, this place was famous for its park, and all thanks to its creator – the estate manager Andrey Timofeevich Bolotov. It was A.T. Bolotov who left the most detailed memories of the construction of the park ensemble, as well as a whole album with sketches of the views of the park, which allows us to present the beauty and grandeur of the estate today. The focus of the virtual reconstruction is on the most beautiful part of the park, which was located to the northwest of the palace, closer to the shore of a Large pond.
The article discusses the techniques of landscape design used by the estate manager A.T.Bolotov at the end of the XVIII century, the features of the construction of the park and the difficulties encountered in creating objects of small architectural forms. The methods and technologies of computer modeling used in creating a three-dimensional historical reconstruction of small architectural forms, the relief of the park, reservoirs and green spaces based on historical sources are analyzed in detail. The work contains a study on the history of the construction of the Bobrinsky Estate park, its development after the resignation of the manager A.T. Bolotov, development and restoration in the XX – XXI centuries, provides an overview of historical sources, including materials of the Restoration and Architecture LLC project in 2014, which allow restoring the historical appearance of the palace and park ensemble of the estate.

Abstract: Modern epoch of information and computer technologies provide new opportunities for solving the problem of cultural heritage preservation. Virtual reconstruction of historical interior is a task different from 3D reconstruction of monasteries, palace and park ensembles or historical urban buildings. Studies of great historical characters are conspicuous of their way of life, personal traits, activity and those internal changes which a person sooner or later transfers to everything around including the surroundings. The article thoroughly discusses a technique of virtual reconstruction of the interior of Nicholas’s I "Bottom" Study in the Winter Palace in 1850-1855 with the help of augmented reality and panoramic video technologies. The topic of historical interior virtual reconstruction often arises in the context of museum studies and is currently underdeveloped. However, the personal side of interiors is no less important for history than external architectural reconstruction.  

Abstract: The article reconstructs the building system of the antique fortress town Gorgippia in the 6th-4th centuries BC that was located in the south-west part of the Bosporan Kingdom. The development of the town center on the territory of modern Anapa for a period of 2.5 thousand years has changed the ancient landscape. However, the traces of the ancient town can be seen when archeological excavation materials, historical documents (cartographic materials and other visual sources in particular) are analyzed. Using modern methodological approaches such as BIM, photogrammetry and aerial photography, 3D modeling and sculpting, the authors step by step create 3D reconstruction of the ancient landscape, restore residential, commercial, religious, administrative and fortification buildings of Gorgippia in the Archaic Era. The results obtained allow the authors to reconstruct the life of the ancient seaside trading town with its distinctive culture, to deeper consider the formation of its individual districts as well as transport routes and the building system itself from its foundation to destruction. The study of the formation processes of the ancient town and its 3D reconstruction contribute to the development of historical urban science in general.

Abstract: Whitestone St. Georger’s Cathedral is one of the most well-known monuments of pre-Mongol stone architecture in Vladimir-Suzdal Rus in the 13th century. The unique feature of the cathedral is the carved whitestone décor which themes are those of Christian iconography, pagan images and floral ornament. In the 15th century the cathedral fell down and was restored, but the integrity of stone reliefs was lost. Later the reliefs were restored by masters of Vasiliy Ermolin in random order thus complicating the task of their correct order reconstruction. During reconstruction the temple became lower, lost its original proportions and the unique ornament. Some reliefs were lost while the others happened in hard-to-get places. Some stone reliefs can be found in the cathedral masonry under the temple roof or in the columns. Inside the building one can see reliefs which have not been used by masters during reconstruction. Researchers have attempted to reconstruct the cathedral many times, but the oddness of reliefs and their multiple damages complicated this work. Modern information technologies (laser scanning, photogrammetry, 3D modeling programs and BIM) provide for solving the problem of reconstructing the cathedral original appearance and lost ancient themes as well as testing the cathedral reconstruction hypotheses at hand. Digitization of stone reliefs allows the researcher to work with them in digital format preserving the integrity of the object. One of the results is the software environment developed by the authors to systematize stone reliefs. Within this environment the authors have reconstructed a number of lost mythical and biblical themes of stone reliefs located on the cathedral walls.
