COMPUTER GENERATED HOLOGRAPHY
at the University of West Bohemia
Who we are
Our main goal is to develop algorithms for generating synthetic holograms of a 3D scene. We consider this as a next step in computer graphics. We belong to Centre of Computer Graphics and Visualization at the Department of Computer Science and Engineering, Faculty of Applied Sciences, University of West Bohemia.
We (computer graphics group) started with holography due to EU project 3DTV: The True Vision. Holographic research was then supported by the national project MŠMT LC-06008.
