Calisto at EuroSIW 2003 Calisto Data AB was an exhibitor at EuroSIW 2003 - the European Simulation Interoperability Workshop which took place June 16-19 2003 in Stockholm, Sweden. "The 2003 Euro SIW is an event encompassing a broad range of model and simulation issues, applications and communities. It will consist of tutorials on the state-of-the-art methodologies, tools and techniques; topical survey sessions as well as a series of forums addressing interoperability issues and proposed solutions." Calisto has extensive experience in creating and coordinating HLA and DIS simulations, as well as developing HLA federates for 2D and 3D visualisation. Drawing from our general experience in 3D visualisation we can create custom 3D models and advanced terrain models for simulation purposes. In our stand in the exhibition area at the EuroSIW conference venue, Folkets Hus we showed examples of visualisations in HLA simulations as well as other applications of visualisation and animation.
