How to set Billboard orientation from a list of Cartesian points

I’m working on functionality to point an svg icon towards its trajectory of travel. Right now these assets czml files are built in python and passed to the front end. Python is passing a list of Cartesian points to the czml file position property. Can that list of Cartesian points be used somewhere to set the billboards orientation? Or is there another method of setting the billboard orientation in python?

Hi there,

Here are the possible properties you can set on a billboard in CZML.
