在网上搜索 AE 创建泰森多边形，都是基于VB或者C#的，

鉴于C#和Java相近，就将C#的代码翻译成Java，

但修改后的程序运行无结果，

经多次尝试，设置了addFromFeatureClass方法的第三个参数，终于获得了泰森多边形。

现把代码共享，如下：

public void CreatVoronoi(IFeatureClass pointFeaCls,IFeatureClass voronoiFeaCls,IPolygon clippingPolygon){
  
  try {
   if (pointFeaCls.getShapeType() == esriGeometryType.esriGeometryPoint)
   {
    if(pointFeaCls.featureCount(null)>2)
    {  
          //
      FeatureClass fc=new FeatureClass(pointFeaCls);      
      IEnvelope pEnv =clippingPolygon.getEnvelope();// (IEnvelope)fc.getExtent();
      pEnv.setSpatialReferenceByRef(clippingPolygon.getSpatialReference());
      ITinEdit pTinEdit = new Tin();
      pTinEdit.initNew(pEnv);
      pTinEdit.addFromFeatureClass(pointFeaCls, null, pointFeaCls.getFields().getField(0) , null, esriTinSurfaceType.esriTinMassPoint,  null);
      pTinEdit.refresh();

      ITinNodeCollection pTinNodeCollection = (ITinNodeCollection)pTinEdit;      
      pTinNodeCollection.convertToVoronoiRegions(voronoiFeaCls, null, clippingPolygon,"","");     
      
      System.out.println("voronoiFeaCls:"+voronoiFeaCls.featureCount(null));
    }
    else
     System.out.println("必须输入至少3个点！");
   }
   else
    System.out.println("必须输入点数据！");
  } catch (AutomationException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  } catch (IOException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  }
//  return voronoiFeaCls;
 }
