Does someone have a handy example of a CZML file that uses sample properties to track a pedestrian walking a terrain.
I need a billboard at the head of the trail for the person, who will have some custome properties I want to see in the infoblock (about 18K samples).
And my assumption is that a separate id for a path that grows as trace of the path (with the head being the billboard). And this would be in a separate packet, shown as a polyline with material.
and Both would have a epoch for the start and then sample properties for each time step
I.e. the epoch would be today at noon, and the sample properties would be 1 second intervals for each position of the pedestrian which would be duplicated for both the polyline and the billboard.
But is there a better way, and I assume someone has done a sandcastle with an example, right?
