The WSCG (formerly Winter School of Computer Graphics), is a series of International Conferences in Central Europe on Computer Graphics, Visualization and Computer Vision, from which it also derives its current full name.
The first event of the series was held with about 20 participants from Czechoslovakia in December 1992. For the last couple of years, the venue was Plzen.
