  16. 16. 1. The quest for extra information 2. What virtual environment to use? 3. Bringing the information into a virtual environment
  17. 17. What Virtual Environment to use? - Investigation of existing virtual environments - Decision to build a new virtual environment relying on existing game engine technology - Investigation of existing game engine technology typically used for visualisations in construction industry
  18. 18. An alternative Virtual Environment 1. Esperient Creator 2. 3DVIA Virtools 3. Unity3D 4. Quest3D 5. StoneTrip ShiVa
  19. 19. The best choice? “None fits, each is possible”: 1. Relatively small differences in functionality 2. Limited level of information exchange with AEC / BIM tools 3. Importance of „side parameters‟: cost, development support, usage statistics, etc. => Unity3D was our choice, BUT a more in-depth study AND usage is to be considered
  20. 20. 1. The quest for extra information 2. What virtual environment to use? 3. Bringing the information into a virtual environment
  21. 21. Information exchange Information modelling in BIM environment
  22. 22. Information exchange routering of the model information FBX representation BIM model import Virtual world in Unity3D export Real-time communication export IFC-to-RDF Service IFC BIM model representation in LOD cloud References to LOD cloud Enriched BIM model
  23. 23. Creation of the virtual world
  24. 24. Implemented functionality connecting FBX representation to the LOD cloud (1)
  25. 25. Implemented functionality connecting FBX representation to the LOD cloud (2) SELECT distinct ?s WHERE { ?s <http://multimedialab.organon.elis.ugent.be/ontologies/IFC2X3#tag> "175853"^^xsd:string . ?s <http://multimedialab.organon.elis.ugent.be/ontologies/IFC2X3#representation> ?o }
  26. 26. Implemented functionality basic user interface (1)
  27. 27. Evaluation Main objectives achieved: - Bring BIM information into the Linked Data cloud - Easy visualisation of building models in a virtual environment - Access BIM information and other information in the LOD cloud from within a virtual environment Further research needed: - Further explore possible connections between building models and information in the LOD cloud - Improve the user interface for a more intuitive usage
