Flooding Barbican is a VR experience project. This project is our attempt to use virtual reality to make people experience the submerged scene of the Barbican Center. This project aims to arouse public awareness of environmental changes and take action. We mainly implement our projects through architectural interior design software such as SketchUp, 3d max and virtual reality software such as unity.
