I was Intern at Kaïnoo in Switzerland for 4 months. During this experience i worked on the 3D creation of a real world apartment. You can try the visit here : http://custimmo.com/visites-virtuelles/location-appartement-savagnier/index.html

I made the 3D mesh of the building and a part of the assets in the visit. For me it was a good experience, i learn how to used Unity for the creation of VR and WebGL applications.
