ABSTRACT
Beijing Hutongs, unique Chinese cultural heritage features, are an important part of Beijing traditional culture. Unfortunately, most of them are being damaged day by day. How to digitise these remaining relics, display them and disseminate them are now key issues. In this paper, we present a 3D interactive virtual roaming system based on Unity3d, which displays Beijing Hutongs in a realistic way. We used two technologies to build the 3D models of Beijing Hutongs. One consisted of manually generating 3D models by using 3D modelling software based on maps of Hutongs and the other consisted of using a multi-view stereo reconstruction technology. Then, we selected a 3D game engine – Unity3d – to build a virtual environment and display the 3D models of Hutong. Furthermore, we added a variety of components to make the scene vivid. Finally, we achieved a 3D stereo effect using Kinect to achieve natural interaction and simulate the four seasons.
