Selected papers from this year’s Workshops on Virtual Environments and on Visualization in Scientific Computing are included in this volume. The papers on VE discuss Virtual Environment System architecture, communication requirements, synthetic actors, crowd simulations and modeling aspects, application experience in surgery support, geographic information systems, and engineering and virtual housing systems.Contributions from the Visualization workshop are presented in four groups: volume rendering, user interfaces in scientific visualization, architecture of scientific visualization systems and flow visualization.
