    • Virtual Reality Callouts - Demonstrating Knowledge With Spatial-Related Textual Information 

      Horst, Robin; Degreif, Anika; Mathy, Marvin; Dörner, Ralf (The Eurographics Association, 2019)
      Virtual (VR) and augmented reality (AR) can bring an added value during the demonstration of knowledge, as for example within an interactive research demo. Callouts are strings of text which are connected by a line to a ...

    • A Virtual Reality Front-end for City Modeling 

      Rando, Eduard; Andujar, Carlos; Patow, Gustavo A. (The Eurographics Association, 2019)
      Current tools for city modeling, including those supporting procedural techniques, have a steep learning curve and require substantial user input and/or skills to create realistic 3D models of cities. In this paper we ...
