I have a bunch of streaming paths that are either loaded by file or streamed from a 3rd party app.
I want them to go through their animation and then just stop and stay there. The epoch is set to the time of when it is loaded. It seems that it won’t display unless an availability is set but I need it to stay indefinitely.
Here is an example of one of the czml packets that can be placed in the Sandcastle:
var viewer = new Cesium.Viewer(‘cesiumContainer’);
viewer.dataSources.add(Cesium.CzmlDataSource.load([{“id”:“document”, “version”:“1.0”},{
“id”: “0”,
“availability”: “2015-03-24T15:47:47.231Z/2015-03-24T16:47:47.231Z”,
“position”: {
“interpolationAlgorithm”: “LAGRANGE”,
“interpolationDegree”: 1,
“epoch”: “2015-03-24T15:47:47.231Z”,
“cartesian”: [

Aside from just setting the availability to a long period of time is there a way to eliminate it from the equation and just have it animate and stop when it’s done? Removing it causes the path not to display and I have tried playing with intervals with no luck.
Side question: There are files that could be loaded that have over 10,000 of these packets. I am already using suspend/resumeEvents when loading these big files but it is still slowing things down to a crawl, even after the animations have finished it doesn’t speed back up. I’m hoping removing availability will help if it’s possible to do but any other tips would be nice.
