I believe that I already know the answer to this based on the looking around I've done but I currently have a need to have a time dynamic cylinder within Cesium. Since it's time dynamic, naturally I reached for CZML but I don't see a way to clamp a cylinder to the ground. I see the option in the czml docs for other entity types but not cylinders.
Is this option simply not supported? Only asking because I don't know how up to date the CZML documentation is since it seems to be kinda old.
