ArcGIS Runtime：如何确定两个3D几何之间的关系

如何解决ArcGIS Runtime：如何确定两个3D几何之间的关系

我想判断两个3D几何之间的关系：

1. 是否重叠
2. 如果重叠，则重叠的部分是什么，重叠的体积是什么。

我想知道ArcGIS中是否有成熟的方法可以实现这种功能，因为对我来说实现特定的数学问题太困难了。

目前，我在ArcGIS中找到了一个相关的类GeometryEngine，但它似乎是无效的：

var onMapLocation = new MapPoint(0,SpatialReferences.wgs84);

var num = 1;
List<MapPoint> points = new List<MapPoint>();

points.Add(new MapPoint(onMapLocation.X,onMapLocation.Y + num,onMapLocation.Z + num,onMapLocation.SpatialReference));
points.Add(new MapPoint(onMapLocation.X + num,onMapLocation.Y,onMapLocation.SpatialReference));
points.Add(new MapPoint(onMapLocation.X,onMapLocation.SpatialReference));

Esri.ArcGISRuntime.Geometry.polygon polygon1 = new Esri.ArcGISRuntime.Geometry.polygon(points);

var num2 = 2;
points = new List<MapPoint>();
points.Add(new MapPoint(onMapLocation.X,onMapLocation.Y + num2,onMapLocation.Z + num2,onMapLocation.SpatialReference));
points.Add(new MapPoint(onMapLocation.X + num2,onMapLocation.SpatialReference));

Esri.ArcGISRuntime.Geometry.polygon polygon2 = new Esri.ArcGISRuntime.Geometry.polygon(points);

var g1 = GeometryEngine.Difference(polygon1,polygon2);

结果g1为空。

这里是参考：

解决方法

我使用了错误的方法，正确的方法如下：

var b = GeometryEngine.Intersects(polygon1,polygon2);
var g3 = GeometryEngine.Intersection(polygon1,polygon2);
var g2 = GeometryEngine.Intersections(polygon1,polygon2);

public static bool Intersects(Geometry geometry1,Geometry geometry2);
public static Geometry? Intersection(Geometry geometry1,Geometry geometry2);
public static IReadOnlyList<Geometry> Intersections(Geometry geometry1,Geometry geometry2);
