  33. 33. SUPPORTING THE USER IN 3D Why  Avoid „getting lost“ situations  Support easy exploration of sites Approaches  Explicit collision model for physics engine  Constraint orbiter camera  Automatic camera path generation  Dedicated „Home“ scenario 33 Computed parabolic camera path
  34. 34. CONCLUSIONS SECTION
  35. 35. LESSONS LEARNED After 4 year development and 5 months up-time:  Distributed, interdisciplinary development is costly  3D reconstruction: multiple iterations required  Add scale elements  Test and tune the application and setup off-site early  Acquiring robust hardware  Press coverage & publications  Success can depend on political issues 35
  36. 36. POTENTIAL FOR FUTURE WORK Make it better  Link to the tangible assets of museum  Include high detail findings  Conduct user evaluation  Indoor visualization and exploration Make it available  Accessible via web using WPVS  Providing the framework for other cities  Licensing the model to the community 36
  37. 37. WRAP UP  Interactive museum application of a complete city  Now permanent exhibition at the RGM  Extensible real-time visualization framework  Potential for future work  Open for collaborations Official Press Release: 3.12.2010 in Cologne 37
