Možnosti 3D grafiky při tvorbě herního levelu se zaměřením na vizuální vedení hráče

This bachelor's thesis examines whether the visual means of 3D graphics, namely light, colour, contrast, shape, composition and spatial arrangement, can guide a player through a game space on their own, without explicit user interface elements. The theoretical part draws on the physiology and cognitive processing of vision, describes the individual principles of visual guidance, compares interface-based navigation with environment-based navigation, and demonstrates their practical use through an analysis of the games Dishonored 2, Metro 2033 and Portal 2. The practical part tests these findings on a custom application built in the Godot engine, designed to isolate three dominant principles, light, a landmark and colour, into separate levels. The solution was evaluated through a user test with sixteen participants, combining measurements of time and movement trajectory with subjective assessment. The results showed that visual guidance can replace the user interface, but its reliability varies depending on the principle used and the nature of the space. Light proved the most reliable, while a landmark in an open space proved the least reliable.
