Urban planning and architecture are disciplines where constant collaboration between different actors is necessary and 3D models are used to present future development projects. The Immersive Terf enables Citizen Engagement in Urban Planning – citizens, city and profession can meet, collaborate, discuss future problems etc. in Terf. The opportunity to walk-through future city/your neighborhood before it is build is important. As Terf is accessible from anywhere, anytime, it saves time and money for everyone who is involved in this process.
