输出avi视频

输出avi视频 我的系统是.net下开发的，要求实现三维漫游时的录制和输出avi,调用了ISceneExporter3d 接口下的ExportScene方法，三维漫游是在arcglobe下开发的，所以用了强制转换，代码如 下，各位大虾指教下啊 private void ExportSceneAnimation(IScene pScene,string sExportFileName,double nVideoDuration,double nQualityPercent) { try { if(timelength!=0) { ISceneExporter3d p3DExporter;//initialize a 3D SceneExporter p3DExporter=new AVIExporterClass() ; p3DExporter.ExportFileName=sExportFileName; //set the viewer of the exporter ISceneVideoExporter pExporter; pExporter=p3DExporter as ISceneVideoExporter; pExporter.Viewer=pScene.SceneGraph.ActiveViewer; //set the video duration pExporter.VideoDuration=nVideoDuration; //set the qualoty percentage of video IAVIExporter pAVIExporter; pAVIExporter=p3DExporter as IAVIExporter ; pAVIExporter.Quality=(int)nQualityPercent; //do the export p3DExporter.ExportScene(pScene); } } catch(Exception err) { MessageBox.Show(err.Message); } } private void button1_Click(object sender, System.EventArgs e) { string sPath; sPath=workPath + @"\Globe\"; pScene=(IScene)pglobe; ExportSceneAnimation( pScene,sPath,timelength,100); // } // }
