Visualisation of semantic architectural information within a game engine environment
- 1. VISUALISATION OF SEMANTIC ARCHITECTURAL INFORMATION WITHIN A GAME ENGINE ENVIRONMENT Pieter Pauwels Ronald De Meyer Jan Van Campenhout
- 2. Re-use / Interoperability through IFC 4D / 5D planning AR / VR visualisations BIM model … Virtual Environment Building Performance Checking
- 3. World Wide Web Semantic Web

- 8. Bring BIM into the Semantic Web BIM
- 9. Example: „Intelligent‟ Virtual Environments See video on: http://www.graphisoft.com/ftp/marketing/vbe/int/01/01.html
- 11. 1. The quest for extra information 2. What virtual environment to use? 3. Bringing the information into a virtual environment
- 12. Bring BIM into the Semantic Web BIM
- 16. 1. The quest for extra information 2. What virtual environment to use? 3. Bringing the information into a virtual environment
- 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. An alternative Virtual Environment 1. Esperient Creator 2. 3DVIA Virtools 3. Unity3D 4. Quest3D 5. StoneTrip ShiVa
- 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. 1. The quest for extra information 2. What virtual environment to use? 3. Bringing the information into a virtual environment
- 21. Information exchange Information modelling in BIM environment
- 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. Creation of the virtual world
- 24. Implemented functionality connecting FBX representation to the LOD cloud (1)
- 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. Implemented functionality basic user interface (1)
- 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
