Mesh Compression


Doc. Ing. Libor Vasa, Ph.D. homepage

Motto: De omnibus dubitandum est

I am currently working as research assistant at Department of Computer Science and Engineering, University of West Bohemia. I am working on the topic of compressing surface models, surface animations with constant connectivity and motion capture data. I am also working on the problem of evaluation of the visual effects of lossy compression of graphical data.
