Visualization in tunnelling-new developments

Abstract

Within the Visualization project of the Austrian Joint Research Initiative (JRI) Numerical Simulation in Tunnelling (SiTu), the Tunnelling Visualization System (TVS) is being developed, to display information in tunnelling. The aim of the Project is to implement a user friendly visualization system, where the data can be displayed in a way that tunnelling engineers can understand. Virtual reality techniques are new in tunnelling and offer a lot of new possibilities. 3D scalar fields are visualised in a novel way. The data to be visualised are either results from numerical simulation or ones describing geological features. Such data have special properties, which have to be considered by the visualization system. The paper presents innovative techniques for this purpose.
