CONVR 2010 - Visualisation of semantic architectural information within a game engine environment

  1. 1. VISUALISATION OF SEMANTIC ARCHITECTURAL INFORMATION WITHIN A GAME ENGINE ENVIRONMENT<br />Pieter Pauwels<br />Ronald De Meyer<br />Jan Van Campenhout<br />
  2. 2. Re-use / Interoperabilitythrough IFC<br />BIM<br />4D / 5D planning<br />AR / VR visualisations<br />BIM model<br />…<br />Building Performance Checking<br />Virtual Environment<br />
  3. 3. World Wide Web<br />SemanticWeb<br />
  4. 4. LOD cloud<br />The Linked Open Data Cloud (LOD)<br />LOD – May 2007<br />Linked Data: Nowwhat?by Tom Heath: Presentation at ESWC2010.<br />http://videolectures.net/eswc2010_heath_ldnw/<br />
  5. 5. LOD cloud<br />LOD – Sep. 2010<br />Linking Open Data cloud diagramby Richard Cyganiak and Anja Jentzsch.<br />http://lod-cloud.net/<br />
  6. 6. LOD cloud<br />Government applications<br />E-commerce sites<br />LOD cloud<br />…<br />Digital Heritage archives<br />Search agents<br />
  7. 7. UGentMultiMediaLab<br />http://multimedialab.elis.ugent.be/<br />Dr. Ir. Davy Van Deursen, Ir. Ruben Verborgh, Dr. Ir. Jos de Roo<br />Prof. Dr. Ir. Rik Van de Walle<br />UGentSmartLab<br />http://smartlab.elis.ugent.be/<br />Ir. Arch. Pieter Pauwels, Ir. Arch. Ruben Verstraeten, Ir. Arch. Tine Jonckheere <br />Prof. Dr. Ronald De Meyer, Prof. Dr. Ir. Jan Van Campenhout<br />
  8. 8. Bring BIM into the Semantic Web<br />BIM<br />LOD cloud<br />BIM<br />
  9. 9. Example: ‘Intelligent’ Virtual Environments<br />BIM<br />See video on: http://www.graphisoft.com/ftp/marketing/vbe/int/01/01.html<br />
  10. 10. ‘Intelligent’ Virtual Environments<br />
  11. 11. The questfor extra information<br />Whatvirtual environment to use?<br />Bringing the informationinto a virtual environment<br />
  12. 12. Bring BIM into the Semantic Web<br />BIM<br />LOD cloud<br />BIM<br />
  13. 13. It exists: upload!<br />BIM<br />LOD cloud<br />http://ninsuna.elis.ugent.be/IfcRDFService<br />
  14. 14. It exists: query!<br />BIM<br />LOD cloud<br />http://ninsuna.elis.ugent.be/SPARQLEndpoint/<br />
  15. 15. It exists: browse!<br />BIM<br />LOD cloud<br />http://ninsuna.elis.ugent.be/rdf/page/ifc/IFC2X3_TC1/ifcBuilding_36<br />
  16. 16. The questfor extra information<br />Whatvirtual environment to use?<br />Bringing the informationinto a virtual environment<br />
  17. 17. What Virtual Environment to use?<br /><ul><li>Investigation of existingvirtualenvironments
  18. 18. Decision to build a new virtualenvironmentrelying on existinggameenginetechnology
  19. 19. Investigation of existinggameenginetechnologytypicallyused for visualisations in construction industry</li></li></ul><li>ExistingVirtual Environments<br />‘Sketchy’ online virtualworlds<br />Fast and intuitive 3D modelling<br />Visualisation<br />High level of interactivitymainlywithobjects and people<br />Design explorers<br />A one-time preview orpresentation<br />Information<br />Interactivitymainlywithinformation<br />
  20. 20. Sketchy online virtualworlds<br /><ul><li>Examples: Second Life, SketchWorlds(, SketchUp)
  21. 21. Plus: fast and intuitive 3D modellingattractive/visual environmentsolid basis of functionality
  22. 22. Minus: limitedinformation exchange with AEC applicationspoorinformation level</li></li></ul><li>SketchWorlds<br />
  23. 23. <ul><li>Examples: NavisWorks, Virtual Building Explorer, goBIM, ICEvision
  24. 24. Plus: optimizedinformation exchange with BIM toolsadvanced features: 4D construction planning, clash detection, design reviewing, simulations,...
  25. 25. Minus: lessintuitive 3D modellingweaker basis of functionality: e.g. online interactivitythroughavatars, focus onpresentationinstead of onmodelling, …</li></ul>Design explorers<br />
  26. 26. Virtual Building Explorer<br />

  28. 28. The best choice?<br />“None fits, each is possible”:<br />Relativelysmalldifferences in functionality<br />Limited level of information exchange with AEC / BIM tools<br />Importance of ‘side parameters’: cost, development support, usagestatistics, etc.<br />=> Unity3D was ourchoice, BUT a more in-depthstudy AND usage is to beconsidered<br />
  29. 29. The questfor extra information<br />Whatvirtual environment to use?<br />Bringing the informationinto a virtual environment<br />
  30. 30. Information exchangeInformationmodelling in BIM environment<br />

  34. 34.

  35. 35. Implementedfunctionalitybasic user interface (1)<br />
  36. 36. Evaluation<br />Main objectives achieved:<br /> - Bring BIM information into the Linked Data cloud<br /> - Easy visualisation of building models in a virtualenvironment<br /> - Access BIM information and other information in the LOD cloudfromwithin a virtualenvironment<br />Furtherresearchneeded:<br /> - Further explore possible connections between building models and information in the LOD cloud<br /> - Improve the user interface for a more intuitive usage<br />
