BufferAnalyst3DParameter bufferAnalyst3DParameter = new BufferAnalyst3DParameter();
bufferAnalyst3DParameter.EndType = SuperMap.Realspace.SpatialAnalyst.BufferEndType.Round;
bufferAnalyst3DParameter.BufferDistance = radius;
bufferAnalyst3DParameter.BufferQuality = 100;
//调用创建缓冲区方法
GeoPoint3D center = new GeoPoint3D(CenterPoint3D);
GeoModel3D geoModel = Geometrist3D.CreateBuffer(center, bufferAnalyst3DParameter, scene.PrjCoordSys) as GeoModel3D;
geoModel.ConvertToGeoModel3D(true);
GeoStyle3D g = new SuperMap.Data.GeoStyle3D();
geoModel.Style3D = g;
g.AltitudeMode = SuperMap.Data.AltitudeMode.RelativeToGround;
scene.TrackingLayer.Add(geoModel, "缓冲区");
scene.Refresh();
Model model = geoModel.Model;
如何在场景里面把这个缓冲区绘制出来
