Multi-channel visual reality system based on PC cluster can give users strong sense of immersion. This paper discusses the synchronous problem in multi-channel visual reality system. For the viewpoint synchronization, this paper brings forward a message communication mechanism based on change of user operating status. This mechanism can reduce the message amount by a large margin, so the message block...
The virtual reality application usually involves automatic roaming. Camera instability is a problem that occurs frequently to automatic roaming, resulting in abrupt change and jittering of vision field. In this paper, a method based on Cardinal spline interpolation is proposed to solve this problem. Given the path controlling points, we first compute a set of high-density interpolate points through...
