验证其可行性。只是模型太小，很难找到。在ConfigurationLoader.cs和ModelFeature类中设置断点监视：

1 public override void Initialize(DrawArgs drawArgs) 2         { 3             if(!IsVisible(drawArgs.WorldCamera)) 4                 return; 5  6             try 7             { 8                 if(meshFileName.EndsWith(".x")) 9                     LoadDirectXMesh(drawArgs);//设置断点，反复改变球，最终找到。注意大概缩放到的经纬度(116.4E,39.9N)10                 else if(meshFileName.EndsWith(".dae")||meshFileName.EndsWith(".xml"))11                     LoadColladaMesh(drawArgs);12                 if (mesh == null)13                     throw new InvalidMeshException();14                 15                 vertExaggeration = World.Settings.VerticalExaggeration;16                 if (isElevationRelative2Ground==true)17                     currentElevation = World.TerrainAccessor.GetElevationAt(Latitude, Longitude);18                 19 20                 isInitialized = true;21             }22             catch(Exception caught)23             {24                 Utility.Log.Write( caught );25                 errorMsg = "Failed to read mesh from " + meshFileName;26             }27         }

同时修改模型的缩放因子ScaleFactor：
