Dear colleagues in the field of visualization research! Visualization research is at a point of reorientation -- many of us are considering questions such as ? What are the most challenging research questions in visualization? ? Where should we head for in scientific visualization research? One sub-field of visualization research, though, namely topology-based methods, still remains rich with a number of not sufficiently solved problems, e.g., topology-based visualization of time-dependent flows or visualization of tensor fields based on their topology. We -- this is Hans Hagen, Holger Theisel, myself (Helwig Hauser), and a few others (see the workshop home page) -- are organizing a workshop on topology-based methods in visualization to be held in Budmerice, Slovakia, on Sept. 29th and 30th (next month!), in a beautiful castle: TopoInVis 2005 http://www.VRVis.at/topo-in-vis/2005/ Below we append a list of talks which have been announced for the workshop to give you a better impression of this workshop. The capacity of the castle allows us to enable a few more researchers (and especially also a few more students) to participate in this workshop. If you respond soon to this eMail (via mailto:TopoInVis@VRVis.at), declaring your wish to participate, then we will issue a special registration code to you (also via eMail) which then will enable you to register for the workshop at the early bird fee. We are prepared to give at most ten of this special tickets away as well as ten more for interested students. We would be happy to welcome you at the workshop, with best regards, Helwig Hauser. -- Doz.
