Many researchers in the field of cultural heritage point to the justification of the use of extended reality to present digital heritage. Research studies, but mainly user reactions, have responded to experiences with extended reality with a positive response. Technological research in the field of extended reality is advancing rapidly. In this review, we will cover the current possibilities and trends of extended reality. Specifically, we will focus on the application in creating interactive multimedia exhibitions in museums and galleries and presenting 3D digital heritage. We believe the practical examples shown will be an inspiration for application developers, content creators, and exhibition curators. Awareness of the possibilities and limits of the current state of technological progress is an essential requirement for utilisation of the full potential of extended reality.

Human efforts to regulate watercourses and the use of water energy in their favour goes back into the past. Although historical water management and utilization structures are the proof of that, only a small number of such structures have been preserved. The article deals with the applied research of the use of modern geodetic laser scanning stations in combination with photogrammetric digital technologies for creating technical documentation and digital visualization of historical structures and national cultural monuments. Specifically, in this case, we will focus on the water utilization buildingsthe water mill and water sawmill in the National Open-Air Museum, Rožnov pod Radhoštěm, Czech Republic. Digital twins created using modern technologies may well serve not only for geo-tourism purposes but also as basis for potential future reconstruction or redevelopment projects.

The issue of virtual tourism penetrates the consciousness of many current explorers and visitors to interesting sites and local attractions. Is it really necessary to physically travel to the chosen location, sacrifice time, money and increase your carbon footprint? The article deals with the issue of creating an application using augmented reality for the presentation of 3D models of cultural monuments. The application is designed for mobile devices, on which museum visitors can view digital copies of selected objects of interest. They can also take a virtual tour of the museum through their mobile devices from the comfort of their home. The introductory part of the article describes surveying of shape and visual properties in situ using photogrammetry and laser scanning. The sequent chapters are an analysis of the creation of 3D models in real scale with photorealistic textures and their presentation in a mixed reality environment. In our case, we will specifically focus on the augmented reality application and its development in the Unity multiplatform game engine. The article aims to describe the development of a mobile marker-based AR application briefly, to demonstrate the possibilities of augmented reality and to indicate the potential benefits resulting from the integration of X-reality into our lives. Specifically, we will focus on the application of AR to cartographic works and the enrichment of the content of classical 2D map works and plans with virtually designed 3D models on their surface.
