基于Skyline的态势拖放中一种减少轨迹变化延时方法研究

Research On a Method to Reduce Delay of Track Change in Situation Drag the Playback Based on Skyline

利用Skyline提供的3D控件技术,容易实现战场态势的三维显示和回放,在回放过程中,用户希望能够进行任意时刻的拖放,以便能够快速查看到用户关心的态势,但在实现拖放时,不仅需要对目标的位置和状态进行更新,而且还需要对划过的轨迹进行快速增补或者擦除,拖动的范围增大,因增补或擦除目标轨迹的延时增加。本文提出一种轨迹分段预处理的方法,将大大减少拖放延时。

By using 3D control technology provided by Skyline, three dimensional display and playback of situation can be easily realized. During the process of playback, the users expect to drag the playback at any time in order to check their concerned tendency rapidly. However, in realizing drag the playback, not only the target positions and statuses are required to be updated, but the target tracks need to be supplemented or erased quickly. The wider of the range of drag playback, the longer time are required to supplement or erase target track. The dissertation presents a track section pretreatment method, which will reduce the delay greatly generated by dragging the playback of wide range.
