AE中点生成面的代码

获取点集。强制转换为多边形。然后在图层上以polygon画出面。

ILayer layer = axMapControl1.Map.get_Layer[3];

IFeatureLayer m_pFeatureLayer = layer as IFeatureLayer;

if( m_pFeatureLayer.FeatureClass.ShapeType == esriGeometryType.esriGeometryPolygon)

{

IPointCollection m_pPointCollection = new PolygonClass();

object missing = Type.Missing;

int icount = newFeature.XLIST.Count; //点集数目

if (icount < 3) return;

for (int i = 0; i < icount; i++) //遍历添加

{

ESRI.ArcGIS.Geometry.IPoint point = new PointClass();

point.PutCoords(newFeature.XLIST, newFeature.YLIST);

m_pPointCollection.AddPoint(point, ref missing, ref missing);

} IPolygon m_pPolygon = m_pPointCollection as IPolygon;

if (m_pPolygon == null)

{

System.Windows.Forms.MessageBox.Show("null");

return;

}

else

{

ITopologicalOperator pTopo = m_pPolygon as ITopologicalOperator;

if (pTopo != null)

{

pTopo.Simplify();

}

IWorkspaceEdit m_pWorkspaceEdit = m_EngineEditor.EditWorkspace as IWorkspaceEdit;

m_pWorkspaceEdit.StartEditOperation();

IFeature m_pFeature = m_pFeatureLayer.FeatureClass.CreateFeature();

m_pFeature.Shape = m_pPolygon as ESRI.ArcGIS.Geometry.IGeometry;

m_pFeature.Store();

m_pWorkspaceEdit.StopEditOperation();

}

熟悉openlayers,cesium,vue,typescript,JavaScript等。
