Celem pracy jest przeprowadzenie badania wydajności silników gier z wykorzystaniem wbudowanych w nie narzędzi. Testy wydajności zostaną przeprowadzone dla różnych konfiguracji sprzętowych. W celu realizacji badania powstanie uproszczona gra 3D z widokiem pierwszoosobowym. Gra zostanie zaimplementowana w różnych silnikach gier: Unity, Unreal Engine, CryEngine, Godot oraz Unigine, co pozwoli zebrać dane do analizy by sprawdzić, który z nich będzie najwydajniejszy.

The purpose of this is to conduct performance testing of game engines using their built-in tools. Performance tests will be conducted for various hardware configurations. In order to implement the study, a simplified 3D game with a first-person view will be created. The game will be implemented in various game engines: Unity, Unreal Engine, CryEngine, Godot and Unigine, which will allow us to collect data for analysis to see which one will be the most efficient.

Solutions designed for indoor navigation are extremely rare compared to outdoor navigation; however, the potential for development is, therefore, very high. Several pilot projects exist in airports, universities, hospitals, and shopping centres. The difficulties in development are currently mainly due to the continuing low quality of indoor positioning and lack of widespread access to high-quality building models. A strong methodological basis for how the interior and exterior of buildings can be cartographically represented in navigation applications has also not yet been developed. Therefore, an attempt was made to design a virtual environment dedicated to supporting the design of indoor navigation applications. Authors present the results of a study aimed at creating a concept of a simulation environment accompanied by the assessment and preliminary validation of its technological feasibility in terms of the method and technology used – although it does not yet constitute a target study. The result was a fully functional prototype of a virtual test environment, which was successfully used in a pilot study on the effectiveness of different types of navigation guidance. The participants’ behaviour within the desktop virtual environment was investigated and their opinions were collected through a questionnaire. This research proved the technological feasibility of the proposed concept and demonstrated the usefulness of the Unreal Engine game engine in building new tools to support the work of cartographers. The created environment will be further developed and used in indoor mapping research.

Dzisiejszą grafikę 3D ciężko wyobrazić sobie bez efektów znanych nam z filmowych produkcji czy wysokobudżetowych gier wideo. Jednak użycie takich upiększeń wiąże się ze zwiększonym zapotrzebowaniem na moc obliczeniową. żeby sprostać oczekiwaniom deweloperów i konsumentów na rynku aplikacji 3D powstały narzędzia do ich tworzenia w postaci kompleksowych silników. Jednym z tych rozwiązań jest silnik Unreal Engine. W poniższym artykule badano wpływ na wydajność wspomnianych efektów - postprocesów. W tym celu przygotowano testową scenę i dwa scenariusze testów.

Today’s 3D graphics are hard to imagine without the effects known to us from film productions or high-budget video games. However, the use of such embellishments is associated with an increased demand for computing power. In order to meet the expectations of developers and consumers on the 3D applications market, tools for their creation in the form of comprehensive engines were created. One of these solutions is the Unreal Engine. The following article examines the impact on the efficiency of these effects - postprocesses. For this purpose, a test stage and two test scenarios were prepared.

W artykule przedstawiono wyniki porównania badania wydajności dwóch silników do produkcji gier Unreal Engine oraz Unity. Analiza porównawcza silników została przeprowadzona na podstawie pomiaru wybranych kryteriów dla dwóch identycznych pod względem funkcjonalności i zasobów gier, stworzonych kolejno w obu wybranych silnikach.

Heterogeneous fog generated with the effect of light scattering and blur

The development of computer graphics forces new requirements on the developers, which will make the virtual world more similar to the real world. One of these elements is the simulation of fog. Common fog algorithms mix the color of the scene with the color of the fog over a certain distance. However, one feature of the naturally foggy scenery is ignored. With the distance and density of the fog, the observed scenery or individual objects become more blurred. In this paper we will present our implementation of the distance fog in the Unreal Engine 4, including the effect of blurring the foggy areas, simulating of light scattering and variations in fog density using noise.

Automatized optimization is useful in generation of appropriate possibilities and is an important and useful tool in the CAD based layout planning. To evaluate the CAD data mathematically and to reduce the amount of data and hence the computing time, in advance there are a lot of steps to do. Combined with a realistic and immersive solution, using the latest hard and software, one can get an excellent impression early in the planning phase.

W dobie coraz większej popularyzacji wirtualnej rozgrywki, twórcy gier komputerowych udostępniają autorskie silniki w formie open source. Dwa najczęściej stosowane darmowe silniki to Unity stworzony przez Unity Technologies oraz Unreal Engine 4 wydany przez Epic Games. Oba znajdują zastosowanie podczas tworzenia gier AAA oraz jako narzędzie do rozwijania umiejętności początkujących programistów. Unity opiera się na programowaniu w języku C#. Natomiast Unreal Engine, który zostanie opisany w niniejszym artykule, korzysta z możliwości jakie daje C++.

Video games developers, due to the still growing popularity of the video games are eager to share their game engines as open-sources. The two most common used and free of them are Unity, developed by Unity Technologies, and Unreal Engine 4 by Epic Games. Both of them are frequently used during the development of AAA games and also as a practicing tool for the beginning programmers. Unity is based on C# language, while Unreal Engine, which will be elaborated in the article, is coded in C++.
