摘要
针对当前虚拟漫游系统存在的问题,对虚拟漫游场景中两种运动方式进行分析,将避障路经规划中的可视图法进行适当改进,提出了"左右判断法",简化了原有算法的时间复杂度,并将运用扩展到三维空间中。在手动漫游方式下实现了漫游物体的智能"滑行"避障。给出了Vega中这两种运动方式的实现步骤。算法在虚拟空间会议系统中得到了验证。
Aiming at the problem of current virtual environment, method of left- right judgment is proposed in automated navigation based on visibility graph method in avoidance obstacle path planning which simplified the original algorithm. Intellectually gliding is available in handle-controlled navigation, both methods is carried out in their algorithms and verified in virtual teleconference system.
