The performance of 3D-graphics hardware and rendering systems is constantly
increasing. Despite this development, concerning research, 3D-desktop systems
are still waste lands compared to their 2D counterparts. Only very few
system exist, and those are sparely documented. At the Institute of Computer
Graphics at the Vienna University of Technology, we are currently designing
and implementing a three-dimensional virtual desktop. This paper provides
insight into the design goals, the structure of the system and describes
the most important and interesting concepts that lie behind.
