开始接触ArcGlobe了，在网上很少相关方面的资料，无论是操作还是二次开发的，都很少，对于我这样一个熟悉二维开发却没有接触过三维开发的人员来说，很是郁闷。
没有办法，只有自己一点点摸索了，结合类库图以及网上的少有的点点博文，开始了自己的漫长探索之路~
IPoint pt = feat.Shape as IPoint;
IEnvelope env = pt.Envelope;
env.PutCoords(env.XMin - 0.005, env.YMin - 0.005, env.XMax+0.005, env.YMax+0.005);
//pGlobe is a variable of type IGlobe
IGlobeDisplay pGlbDisplay = this.axGlobeControl1.Globe.GlobeDisplay;
//get the ActiveViewer
ISceneViewer pViewer = pGlbDisplay.ActiveViewer;
//get the Camera of the current viewer
ICamera pCamera = pViewer.Camera;
//Set the GlobeCamera to the camera of the ActiveViewer
IGlobeCamera pGlobeCamera = (IGlobeCamera)pCamera;
ISceneViewer sceneViewer = pGlbDisplay.ActiveViewer;
pGlobeCamera.SetToZoomToExtents(env, this.axGlobeControl1.Globe, sceneViewer);
