安装必要的库导入所需的模块创建Point对象使用Point对象创建Polygon对象验证Polygon对象的正确性可视化Polygon 结论 通过上面的步骤,我们成功地使用Python的shapely库将一系列点连接成一个多边形,并通过matplotlib进行可视化。在实际开发中,这种操作在地图绘制、空间分析等领域非常常见。希望本指南能够帮助您更好地理解Python中Po...

point lies on an edge of polygon. If none of the conditions is true, then point lies outside. 1. 2. 3. 4. 5. 6. 7. 那这样,我们有我们目标点的坐标,我们又有我们区域的大概的形状,那这样我们就可以确定,我们的目标点的所在区域了 下面是代码,用python实现的 # Library # 这个是用来判断点在...
Shapely Other Geomagic Wrap FugroViewer ArcGIS 3D Footnotes 主要是介绍一些3D point cloud与Mesh 相关的软件,主要是软件、功能也很多,有利于以后查找。 Open Source Open Source主要是以C++为主,随着python的流行,后来也有很多基于python的库。 CGAL CGAL 是目前处理point cloud 和 Mesh首推的库,功能很多,包括点云...
