【iObjects java】如何实现桌面场景中的多边形查询功能

Answer 1

【解决方法】 GeoRegion3D georegion3d = e.Geometry as GeoRegion3D; GeoRegion georegion = georegion3d.ConvertToRegion(); DatasetVector datasetvector =m_Workspace .Datasources [0].Datasets [“New_Point3D”] as DatasetVector; Recordset recordset = datasetvector.GetRecordset(false, CursorType.Static); GeoModel3D geomodel3d = ModelBuilder3D.LinearExtrude(georegion, true, 10, 0, 0, 0); List list = SpatialQuery3D.SpatialQuery(geomodel3d, recordset,PositionMode.Contains);
