One of the tasks of the project presented in this paper was to document, reconstruct in 3D, and visualize a collection of Neolithic pottery from the area of Lesser Poland. The digitization was performed using a structured-light scanner and, in two cases, photogrammetric software. The reconstructions were modelled on the basis of digital representations of scans of original fragments by adding successive layers of the reconstructed shape directly onto the recorded artefact. Apart from preparation of source files for sharing, a number of visualisations were made, including renders and 3D animations.

Aim of the project was to state the most suitable methods of visualization of spatio-temporal chase in historical build-up area from the tourist’s point of view. The case study of the project is focused on fortress Olomouc, which was almost completely demaged at the end of the 19th Century. In the article five approaches are discussed – textual description of changes, comparison of historical and recent Picture or photos, overlaying historical maps over the orthophoto, enhanced visualization of historical map in large scale using the third dimension and photorealistic 3D models of the same area in different ages. All mentioned methods were geolocalizated using the Google Earth environment and multimedia features were added to enhance the impression of perception. Methods are evaluated according to technological demandingness of the processing and preparation and user perception. Usability study is processed using the eye-tracking technology and questionaire survey.

The article addresses three virtual reconstruction models of the city Brno for years 1400, 1645 and 1749. Attention is devoted not only to their characteristics, but also the sources, on which they were based, and their contemporary contexts. It also mentions the software used for the creation and presentation of these models.

Three-dimensional recording techniques, although growing rapidly in efficiency and applicability for archaeologists, have still not been turned to full account, mainly because they require for the most part expensive equipment and know-how. In this respect, photogrammetry is unique, being relatively cheap and easy to use. The joint Armenian–Polish archaeological project in Metsamor drew on the possibilities of this technology, which is relatively new to archaeological proceedings, in the daily recording system used at the site. The following article discusses the step-by-step application of photogrammetry in field documentation and its positive impact on archaeological work, Metsamor being taken as a case in point.

Określanie chronologii zapisów ma podstawowe znaczenie w sprawach, w których istnieje podejrzenie fałszerstwa dokumentu przez dopisanie, uzupełnienie w treści gotowego dokumentu, antydatowanie, a także w przypadku wykorzystania dokumentów podpisanych in blanco i stanowi jeden z najtrudniejszych problemów w kryminalistycznej ekspertyzie dokumentów. Dotychczas uzyskiwane wyniki, przy wykorzystaniu różnych metod badawczych, nie pozwalają na jednoznaczne rozstrzygnięcia. Dotyczy to zarówno prostych metod mikroskopowych, technik dyfuzyjnych, jak i metod wykorzystujących technologie bardziej zaawansowane (np. spektroskopia Ramana, badania elektrostatyczne, mikroskopia skaningowa i konfokalna). Ten problem badawczy określany jest w literaturze i praktyce sądowej jako oznaczanie "względnego wieku" dokumentu. Artykuł stanowi wprowadzenie do cyklu publikacji prezentujących efekty badań realizowanych w ramach projektu rozwojowego będącego wspólnym przedsięwzięciem naukowym Katedry Kryminalistyki Uniwersytetu Warszawskiego i Polskiego Towarzystwa Kryminalistycznego. Celem projektu było opracowanie metod badania wieku względnego zapisów wykonanych różnymi technikami na podłożu papierowym, w tym również takich, które nie krzyżują się ze sobą.

Determining the chronology of writing is essential in cases of suspected document forgery by addition, adding to the content of a finished document, backdating, and also in the case of the use of documents signed in blank, and is one of the most difficult problems in the forensic document examination. The results obtained so far, using a variety of examination methods, do not allow for unambiguous decisions. This applies both to simple microscopic methods, diffusion techniques and methods using more advanced technologies (such as Raman spectroscopy, electrostatic examination, scanning and confocal microscopy). The research problem is referred to in the literature and forensics as the determination of document "relative age". The article is an introduction to a series of publications presenting the results of the research carried out within the framework of a development project, a joint venture of the Department of Forensic Science, The University of Warsaw (UW) and the Polish Forensic Association (PTK). The aim of the project was to develop methods for testing the relative age of the writing made by various techniques on a paper substrate, including non-intersecting.
