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

An alternative Virtual Environment

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

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
