The authors address the problem of passive navigation in large buildings. Based on the example of several interconnected buildings housing departments of the Lublin University of Technology, as well as the conceptual navigation system, the paper presents one of the possible ways of leading the user from the entrance of the building to a particular room. An analysis of different types of users is made and different (best for them) ways of navigating the intricate corridors are proposed. Three ways of user localisation are suggested: RFID, AR and QR markers. A graph of connections between specific rooms was made and weights proposed, representing "the difficulty of covering a given distance". In the process of navigation Dijkstra's algorithm was used. The road is indicated as multimedia information: a voice-over or animated arrow showing the direction displayed on the smart phone screen with proprietary software installed. It is also possible to inform the user of the position of the location in which he currently is, based on the static information stored in the QR code.

Article shows two modern methods of creating realistic 3D spaces. The comparison includes 3D scanning with FARO Focus 3D X330 and 3D modelling in Blender 2.8. Analysis of methods for creating realistic 3D spaces can be useful in many fields e.g.: architecture, 3D printing, games industry, visualization, criminalistics, reverse engineering or monument documentation. The paper also describes process of generating a chosen space for each method. Each of the two approaches is assessed in terms of the expenses, precision and degree of reflecting reality.. Article includes an analysis of encountered problems and their possible sources. The paper also evaluate usefulness and profitability for each method. A research was carried out and focused on degree of immersion for VR visualizations depending on the used method.
