Agustín de Betancourt y Molina was one of the most distinguished engineers of the eighteenth and nineteenth centuries with numerous contributions to various fields of engineering, including civil engineering. This research shows the process followed in the documentation of the cultural heritage of that Canary engineer, especially in the geometric documentation of a machine for cutting grass in waterways presented in England in 1795 after three years researching on theory of machines. The baseline information has been recovered from the Canary Orotava Foundation of History of Science who has spent years collecting information about the Project Betancourt, in particular, planimetric information as well as a small report on its operation and description of parts of machine. From this information, we have constructed a three dimensional (3D) model using CAD techniques with the use of Solid Edge ST7 parametric software, which has enabled the team to create the 3D model as well as different detail plans and exploded views.

Modelling Techniques

The morphometric and photogrammetric knowledge, combined with the historical research, are the indispensable prerequisites for the protection and enhancement of historical, architectural and cultural heritage. <br><br> Nowadays the use of BIM (Building Information Modeling) as a supporting tool for restoration and conservation purposes is becoming more and more popular. However this tool is not fully adequate in this context because of its simplified representation of three-dimensional models, resulting from solid modelling techniques (mostly used in virtual reality) causing the loss of important morphometric information. <br><br> One solution to this problem is imagining new advanced tools and methods that enable the building of effective and efficient three-dimensional representations backing the correct geometric analysis of the built model. <br><br> Twenty-year of interdisciplinary research activities implemented by Virtualgeo focused on developing new methods and tools for 3D modeling that go beyond the simplified digital-virtual reconstruction used in standard solid modeling. Methods and tools allowing the creation of informative and true to life three-dimensional representations, that can be further used by various academics or industry professionals to carry out diverse analysis, research and design activities. <br><br> Virtualgeo applied research activities, in line with the European Commission 2013’s directives of Reflective 7 &amp;ndash; Horizon 2020 Project, gave birth to GeomaticsCube Ecosystem, an ecosystem resulting from different technologies based on experiences garnered from various fields, metrology in particular, a discipline used in the automotive and aviation industry, and in general mechanical engineering. <br><br> The implementation of the metrological functionality is only possible if the 3D model is created with special modeling techniques, based on surface modeling that allow, as opposed to solid modeling, a 3D representation of the manufact that is true to life. <br><br> The advantages offered by metrological analysis are varied and important because they permit a precise and detailed overview of the 3D model’s characteristics, and especially the over time monitoring of the model itself, these informations are impossible to obtain from a three-dimensional representation produced with solid modelling techniques. The applied research activities are also focused on the possibility of obtaining a photogrammetric and informative 3D model., Two distinct applications have been developed for this purpose, the first allows the classification of each individual element and the association of its material characteristics during the 3D modelling phase, whilst the second allows segmentations of the photogrammetric 3D model in its diverse aspects (materic, related to decay, chronological) with the possibility to make use and to populate the database, associated with the 3D model, with all types of multimedia contents.

Editing Process

This paper emphasizes the benefits of part-model editing process that does not depend on hystory-based modelling system. The use of synchronous technology in mechanical engineering applications allows the NC programmer to efficiently generate the NC program regardless the source of 3D model. The programming and machining process can be more efficient if the intuitive geometric changes on 3D model are allowed. Synchronous technology makes possible NC programmer’s intervention over 3D model geometry, without breaking the rules defined in CAD. Synchronous technology works with both, native and non-native models and it is available in NX and Solid Edge. With synchronous technology, the changes are performed with or without regard to the history of the model.

This article shows the geometric modeling and virtual reconstruction of the optical telegraph by Agustín de Betancourt and Abraham Louis Breguet developed at the end of the 18th century. Autodesk Inventor Professional software has been used to obtain the three-dimensional (3D) model of this historical invention and its geometric documentation. The material for the research is available on the website of the Betancourt Project of the Canary Orotava Foundation for the History of Science. Thanks to the three-dimensional modeling performed, it has been possible to explain in detail both its operation and the assembly system of this invention in a coherent way. After carrying out its 3D modeling and functional analysis, it was discovered that the transmissions in the telegraph were not performed by hemp ropes but rather by metal chains with flat links, considerably reducing possible error. Similarly, it has also been found that the use of the gimbal joint facilitated the adaptability of the invention to geographical areas where there was a physical impediment to the alignment of telegraph stations. In addition, it was not now necessary for the telescope frames to be located parallel to the mast frame (frame of the indicator arrow) and therefore they could work in different planes.

<p class="VARKeywords">This article sets a framework for computer-based visualisations of cultural heritage sites. The project focuses on a workflow for a visualisation illustrated on a specific solution for the site of Çukuriçi Höyük, a tell settlement in Turkey. With the virtual presentation, an interdisciplinary research group tries to offer complex scientific results to the general public as well as to experts. The team utilised data acquisition and communication techniques, interpretative approaches, and dissemination methods. The three-dimensional (3D) outcome is based on a large amount of scientific data, usually available only via analogue or digital publications for a specialised audience. The work focused on constructed and personal authenticity to reach the viewer’s feelings. As an interpretative narrative, the daily lives of the inhabitants were selected. A communication plan was constructed, and a video animation with narration and a musical background was selected as the most appropriate communication tool. The movie was divided into four chapters <em>(Introduction, Neolithic Period, Chalcolithic Period </em>and <em>Early Bronze Age Period</em>). A separate webpage was designed to provide additional information when the video is viewed online. The webpage was divided into tabs that describe each chapter and three additional topics (<em>Visualisation Process, Further Reading, </em>and <em>Credits</em>). The video was shared in different settings, e.g. at public talks and on social media. The process resulted in a complex workflow that consists of several stages: data acquisition, first interpretation, 3D model creation, communication plan, second interpretation, 3D model adjustment, and dissemination output. Each stage of the workflow serves as an example to show the types of nodes these parts can include. The result is a flexible framework with predefined process stages, which can be re-used for similar projects.</p><p>Highlights:</p><ul><li><p>Computer-aided visualisations bring hidden cultural heritage to life –an individual outcome for Çukuriçi Höyük, a tell settlement in Turkey.</p></li><li><p>The interdisciplinary team combined data acquisition and communication techniques, interpretative approaches, and dissemination methods for achieving the best result.</p></li><li><p>Integrative framework optimises the information and communication potential of virtual visualisations with the help of pre-defined workflow stages.</p></li></ul>

Each year the problem of historical and cultural heritage preservation becomes more piercing as an increasing number of monuments are gradually ruined. Manors once being a special cultural phenomenon of the social history of our country are no exception. The article analyzes the complex of sources with sufficient information value for creating a virtual 3D-reconstruction of the main house and elements of Olgovo manor complex near Moscow in the late 19th - early 20th centuries as well as scrutinizes the sources and papers to study the history of Olgovo and its owners (17th - 20th centuries). The reconstruction of the main house and the elements of Olgovo manor complex allows the author to visualize the appearance of the currently ruined cultural heritage monument and demonstrate the practice of applying methods of three-dimensional computer modeling to historical research by the example of manor reconstructions. The author describes the use of modern software (Adobe Photoshop CS6, SketchUp and Twinmotion) to solve the goals set. The research was carried out within the project of the Historical Information Science Department of Moscow State University aimed at reconstructing virtual appearance of Moscow Oblast manors in close cooperation with the Central State Archive of Moscow Oblast.
