Abstract. In the context of this paper, a virtual reality application that allows each user to perform basic topographic processes on an already created 3D model inside a virtual environment was developed. Specifically, it is an application that allows the user to perform measurements of distances between two points in three-dimensional space and measurement and extraction of the three-dimensional coordinates of any point inside the virtual reality environment. Furthermore, the created application was evaluated in terms of its functionality, its usability and metric accuracy. Before the developing stage a research was done in order to determine which virtual reality system and which game engine is most suitable to use and finally the HTC Vive® virtual reality system and the Unreal Engine 4 game engine were used. Before all that, the concept of the virtual reality science was defined and also the virtual reality technologies in today's world were analyzed.
