Before individual activities in the field of endoscopy are to be explained a brief insight into the surrounding thereof may prove meaningful. At the Department for Spatial Simulation endoscopy is not treated independently, but principally in connection with other simulation techniques such as the simulation of architectural spatial formations in full-scale, CAAD, stereoscopy and holography. The term SAAD (Simulation Aided Architectural Design) refers to a combination of spatial simulation techniques. This aspect plays a major role at the Vienna University of Technology.
