I would like to move my camera smoothly around my aircraft. With viewer.trackedEntity = airplane, I have tried including multiple camera positions in czml:

"viewFrom" : {
	"epoch" : "2012-08-04T16:00:00Z",
	"cartesian" : [
	0, 100.0, 100.0, 100.0,
	100, 200.0, 200.0, 200.0
	]
}

But the camera stays locked in one position. Shouldn't this work? (https://github.com/AnalyticalGraphicsInc/czml-writer/wiki/ViewFrom says "Interpolatable: yes")

Or is there a way to animate viewer.camera.position dynamically?
