| Popis: | In virtual environments, navigation is one of the most fundamental tasks that requires timely collision detection and collision avoidance mechanisms [1]. It was shown that when navigation is constrained to moving on a terrain surface, the problem of collision detection can be reduced from 3D to 2D case, by rasterizing all 3D objects that constitute travel obstacles and encoding them into a terrain elevation image map, using a dedicated color [2]. The original algorithm was developed for static Virtual Reality (VR) scenes explored by a single user, immersed into the scene with a head mounted display and navigating by continuous steering. |
