DIGITAL GRAPHICS AND VIRTUAL REALITY FOR THE PRESENTATION OF ANCIENT ROMAN CONSTRUCTION TECHNIQUESIn the field of construction engineering, the use of computer imaging has become instrumental in thecreation of educational simulations, which can be used to present techniques and details in a mannerthat is easily understood by a general audience. Virtual reality can be considered as an extension of thispractice, due to the immersive effect that virtual simulations can pose, which will enable the client toview a process in real time from any angle and analyze the various specific methods involved in itsprogression. Because it is increasingly used in the simulation of modern buildings and constructionprojects, the same system can be combined with archaeology and historical studies as a means ofdemonstrating the construction of ancient monuments. This same technique can also be used to presentthe various aspects of ancient engineering to historians and archaeologists, which will enable them tounderstand the specifics of various monuments more clearly.For this specific simulation, the intent is to replicate the construction of the Roman Colosseum – aunique undertaking – which can be adjusted for presentation to various audiences, ranging fromacademic scholars in history or engineering to students in relevant topics. The intention is to recreateeach step of the construction of this monument and, aside from a full assembly of the structure that canbe viewed from both the inside and outside within a realistic environment, specific processes can alsobe highlighted and demonstrated within the various sectors of the construction timeline. To implementthis process, a complete model was initially created using engineering graphics software that couldtheoretically be constructed based on the latest architectural data and broken up into individualfragments for processing. This “top-down” approach, while usable for simulating the completedmonument, presented a risk of large amounts of data slowing down the simulation process, with themeasures taken to reduce the processing load being implemented at the cost of model accuracy andrealism, particularly in the interior. In contrast, a more updated method, referred to as a “bottom-up”approach, may be more viable both for the modeling process and for the simulation, as it replicates thevarious steps individually and realistically and is therefore more compatible with a real-time simulatedreconstruction. This use of virtual reality is therefore advantageous because the demonstration ofconcepts such as operations of construction, labor organization, and the prominent architecturalstrategies of the era can be set up via a bottom-up approach which both streamlines feature complexityand presents data in a clear and comprehensive manner.The analysis of this prospect involves the most up-to-date simulation that can be created from thecurrent research, which uses the top-down approach. This project will be beta-tested by a sampleaudience which provides feedback on realism, informativeness, accuracy, and authenticity, along withprofessionals in various fields, including history, archaeology, architecture, and engineering. In thisway, the program can be refined to convey the most up-to-date and consistent information, opening upnew possibilities for digital education in all of these fields.
