The joint virtual reality project by UFA and Fraunhofer Heinrich-Hertz-Institute (HHI) is committed to preserving these voices. With the technology of the volumetric video, whose basic technology “3D Human Body Reconstruction” was developed by researchers at Fraunhofer HHI, the memories of the Holocaust survivors are recorded for future generations. In the volumetric studio of Volucap GmbH, the Jewish eyewitness Ernst Grube reports on the experiences in National Socialist Germany and the persecution. Ernst Grube was captured in the volumetric studio with the help of 32 cameras. A lifelike three-dimensional image of Ernst Grube is then calculated from the video information using computer vision methods and can be directly integrated into a virtual world.
