| 摘 要： | 窗口检索是许多信息系统的基本功能之一,包括单窗口检索和多窗口检索。多窗口检索就是判断点状日标位于哪个多边形内,即“点位探测”。在本文介绍了追踪法点位探测的基本思想和方法,并把这一思想引入矢量多边形叠置运算中,有效地提高了矢量叠置的求交效率。

| Abstract: | Window retrieval is one of the basic functions of many information systems. It includes single-window retrieval and much-window retrieval. Much-window retrieval, detecting point, is to decide in which polygon the point be.This paper introduces the theory and method of detecting point, and applys this theory to the operation of polygon-onpolygon, thus improving the intersection efficiency of polygon-on-polygon. |
