Hi how to stream live czml packets and process in java script without making UI freeze and without starting the scenario from the begining, whenever i send new czml packet of an object from server with new updated Cartesian coordinates along with epoch time and elapsed seconds from epoch time , the whole scenario will restarts from the beginning after processing the packet. So how to avoid scenario restart. Basically i want object in the scenario moving with real time , where real time Cartesian coordinates are fed from server.

It sounds like you are calling CzmlDataSource.load or CzmlDataSource.loadUrl each time. This causes existing data to be removed. If you simply want to update data, call CzmlDataSource.process or CzmlDataSource.processUrl.

Also, when you construct the Viewer, be sure to pass the automaticallyTrackDataSourceClocks option and set it to false. This will prevent automatic clock adjustment based on loaded data.

  • Thank you very much Matthew. Actually i was processing the czml packet using the CzmlDataSource.process only, but the mistake i was doing was adding the dataSource object again and again as and when i processed. so that was causing the scenario to reset. Thanks for your valuable time. I will certainly try you next suggestion about constructing the Viewer. – maruthi.others Konda Feb 03 '15 at 12:04
