Trójwymiarowa dokumentacja dzieł sztuki przy użyciu precyzyjnego skanu 3D – rewolucja naukowa i estetyczna

AbstractToday’s world witnesses the appearance of new techniques and devices enabling the creation of a digital reproduction of shapes and colours of spatial objects. The majority of available solutions, be it hardware or software, are adjusted to the reproduction of a given surface shape in industrial applications. Attempts to apply such systems in 3D digital representation of cultural heritage objects fall far below the expectations of both experts in the field (historians, conservators of art) and simple users interested in everyday contact with historic objects. The situation stems from very high demands for precision in reproducing shapes and colours of measured objects, necessary in conveying an extraordinary character of the finest of works. Technological limitations of the currently existing solutions result in two major problems. The first one consists in the digital models being insufficiently detailed, the second one in their low documentary value caused by the need to reprocess the measuring data several times. Insufficient spatial definition of the acquired data and the need to create simplified models in form of networks of triangles blur the unique features of visualized objects. Repeated interference in the amassed data by its filtration, polishing and simplification, as well as the need for graphic designers to fill in spots unsusceptible to measure, lead to the loss of reliability and documentary value of the processed material. The authors of the article have dedicated a number of years to the development of a 3D method of recording surfaces of works of art. The method in question would on the one hand provide experts with an advanced analytic tool and on the other would allow its users, craving for an aesthetic and emotional reception of art, to fully appreciate all details of displayed objects. To meet these requirements it became necessary not only to take into account specific types of surfaces found in various works of art but also to specify optimal technical parameters of the final digital record and also the functional value of the software created to analyse and visualize spatial models. So far, obtaining high-parameter measurements which would guarantee usefulness of the collected data both today and in the future has been possible only after a precise determination of minimum technical parameters of 3D scans and following the construction of specialised reference measuring systems. A particularly important part of the research is the creation of a visualization software which helps the end user to view the collected data in full definition by operating a virtual camera in real time and by selecting the type of illumination used on the viewed object.
