Systemy nawigacyjne to zaawansowane narzędzia, które pozwalają tworzyć postacie inteligentnie poruszające się po świecie gry. W ramach niniejszej pracy przeprowadzono analizę porównawczą autorskiego systemu nawigacji o nazwie AlchemyNavigation oraz wbudowanego narzędzia silnika Unity - systemu NavMesh. Do przeprowadzenia badań wykorzystano autorską aplikację zbudowaną przy pomocy silnika Unity, w ramach której zaimplementowano tożsame scenariusze badawcze bazujące na porównywanych systemach. Finalnie, na podstawie zebranych wyników oraz dokumentacji badanych systemów zrealizowana została analiza porównawcza, która dowiodła tezy że własne rozwiązania mogą dorównać rozwiązaniom domyślnym, a także, że pozwalają wprowadzać nowe funkcjonalności.

Navigation systems are advanced tools that allow you to create characters intelligently moving around the game world. The purpose of this thesis was to conduct a comparative analysis of the proprietary navigation system “AlchemyNavi-gation” and the built-in tool of the Unity engine - “NavMesh”. An proprietary application created with the Unity engine was used to conduct the research, under which identical scenarios based on the tested systems were implemented. Finally, on the basis of the collected results and documentation of the research objects, a comparative analysis was carried out and proved the thesis that own solutions can match the default solutions.
In this paper, the possibility of replacing tensile extensometers with a non-contacting device for measuring elongation has been analyzed. An example of a non-contacting device is a Digital Image Correlation System (DIC). Such systems are widely used in various areas, for example, biology or modern engineering. DIC systems have several advantages that seem to be promising for testing modern materials. The most important is the fact that there is no physical contact between the sample and the DIC and therefore no additional force is applied during the experiment. On the other hand, a lack of contact with the sample can cause large measurement inaccuracies. Another advantage would be that a DIC can measure strain on the whole surface of the sample in all directions, instead of measuring part of the surface in one direction like in other extensometers. Because of these abilities, the environment impact on test bench (DIC + load device), and differences between conducted experiment with normalized tensile test needed to be investigated. The testing machine was replaced by a DIC system cooperating with a tension-compression module. The proposed method was used to monitor and record the images to determine the basic properties of 13MnSiCr7 grade steel. Twelve tests were performed. The analysis was done by comparing the values of mechanical properties obtained in a static tensile test, such as yield strength, tensile strength, Young’s modulus, elongation of the material; with the values of these properties determined experimentally. For each sample, stress-strain curves were evaluated. To check if the results were correct, a Q-Dixon test was performed in each case, confidence intervals were also calculated. Finally, the obtained properties were compared with those from the standard tensile test acquired from the manufacturer’s material card.
