I'd like to use STK Components with the Cesium beta jar to generate a CZML file which contains vector information that will be displayed on the Cesium globe when the CZML is added to it. I've created a GraphicalVector object and set its Vector, VectorGraphics, and Point information. I've also added an IdentiferExtension. When I use the CesiumWriter to generate the CZML, I'm getting a string like this "" which I'm assuming is just writing out the beginning and ending bracket for a JSON object. Can someone supply a bit of working example code for me to see how to correctly generate a vector (velocity, sun, etc...) in CZML? What I'm trying to do is obviously not quite right.
