Automatic Virtual Portals Placement for Efficient VR Navigation

Lili Wang, Yi Liu, Xiaolong Liu, Jian Wu

Abstract: Portals placement in a large virtual scene can help users improve navigation efficiency, but determining the number and the positions of the portals has some challenges. In this paper, we proposed two automatic virtual portals placement methods for efficient VR navigation. To reduce the number of reverse redirections, we also proposed a real-time portal orientation determination algorithm. For any given single-floor outdoor virtual scene, our methods can automatically place the portals.
