In 12 selected papers common problems in visualization are discussed. These include: adaptive and multi-resolution methods; feature extraction; flow visualization; and visualization quality. Four papers focus on aspects of mesh reduction, mesh compression, and increasing the quality of the resulting mesh. Two extensions on particle tracing are presented, as well as a paper on the simulation of material transport. Two papers discuss feature extraction in dynamics systems and the accuracy of algorithmic extracted features. Three papers focus on stereoscopic volume rendering, on the visualization of atomic collision cascades and of quality of visualization systems in general.
