KML file with gx:Tour in Cesium


i build a KML file with flight loactions inside a gx:tour element.
It works perfect in GE but since Cesium don't support gx:tour or lookAt/Camera
i don't know how to build this in Cesium.

I got positions and directions for the camera and i want to fly the excact path.
Is there any chance to do this in cesium ?

Is it maybe possible to do this in CZML? It does not have to
be KML, i can get the data in any form i want, but i have to use Cesium.

You can create a CZML file with an entity. Using the SampledPositionProperty you can set the time for each location.
