3D Integration 32

Supporting the user in 3D : 

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

COnClusions : 

COnClusions SECTION

Lessons Learned : 

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

Potential for Future Work : 

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

Wrap Up : 

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 37
